Zambia Assessment of Tuberculosis (TB) and HIV in the Mines (ZATHIM): implications for programs and policies.

BACKGROUND: Mineworkers in Southern Africa have the highest rates of tuberculosis (TB) among working populations in the world (The World Bank, Benefits and costs associated with reducing tuberculosis among Southern Africa's mineworkers, 2014), making mineworkers a key population for TB program efforts. The current evaluation aimed to characterize mineworkers and former (ex-) mineworkers, and assess knowledge, attitudes and practices related to TB and HIV care among mineworkers and healthcare workers (HCWs) in Zambia. METHODS: A mixed-methods evaluation of current and former (ex-) mineworkers and HCWs was conducted in the Copperbelt and North-Western provinces, Zambia. Knowledge, attitudes and practices (KAPs) related to TB care and policies were assessed using a structured survey. Focus Group Discussions (FGDs) were conducted with current and ex-mineworkers to understand perceptions, practices, and barriers related to accessing healthcare for TB. RESULTS: Overall, 2,792 mineworkers and 94 HCWs completed the KAP survey, and 206 (171 current, 71 ex-) mineworkers participated in FGDs. Mineworkers and ex-mineworkers were knowledgeable about TB symptoms (cough; 94%), transmission (81.7%) and treatment (99.2%). Yet, barriers to seeking care were evident with 30% of mineworkers experiencing cough, and 19% reporting 2 or more TB symptoms at the time of the survey. The majority of mineworkers (70.9%) were aware of policies barring persons from working after a diagnosis of TB, and themes from FGDs and HCW comments (n = 32/62; 51.6%) recognized fear of job loss as a critical barrier to providing timely screening and appropriate care for TB among mineworkers. The majority (76.9%) of mineworkers indicated they would not disclose their TB status to their supervisor, but would be willing to share their diagnosis with their spouse (73.8%). CONCLUSION: Fear of job loss, driven by governmental policy and mistrust in mining companies, is a major barrier to healthcare access for TB among mineworkers in Zambia. As a result of these findings, the government policy prohibiting persons from working in the mines following TB disease is being repealed. However, major reforms are urgently needed to mitigate TB among mineworkers, including ensuring the rights of mineworkers and their communities to healthy living and working environments, improved social responsibility of mining companies, and facilitating choice and access to affordable, timely, and high-quality healthcare services.

New approach for reduction of diesel consumption by comparing different mining haulage configurations.

The mining operations of loading and haulage have an energy source that is highly dependent on fossil fuels. In mining companies that select trucks for haulage, this input is the main component of mining costs. How can the impact of the operational aspects on the diesel consumption of haulage operations in surface mines be assessed? There are many studies relating the consumption of fuel trucks to several variables, but a methodology that prioritizes higher-impact variables under each specific condition is not available. Generic models may not apply to all operational settings presented in the mining industry. This study aims to create a method of analysis, identification, and prioritization of variables related to fuel consumption of haul trucks in open pit mines. For this purpose, statistical analysis techniques and mathematical modelling tools using multiple linear regressions will be applied. The model is shown to be suitable because the results generate a good description of the fuel consumption behaviour. In the practical application of the method, the reduction of diesel consumption reached 10%. The implementation requires no large-scale investments or very long deadlines and can be applied to mining haulage operations in other settings.

A comparative life cycle assessment of material handling systems for sustainable mining.

In this comprehensive LCA comparison study, main objectives are to investigate life cycle environmental impacts of off-highway mining trucks and belt conveyors in surface mining. The research methodology essentially entails determination of the functional unit as 20,000 tons/day coal production transported for 5 km distance. After the system boundary was selected as the entire life cycle of material handling systems including pre-manufacturing of steel parts and plastic components, manufacturing, transportation, and utilization data was compiled from equipment manufacturers and the Eco-invent database. Life cycle impact categories for both material-handling systems were identified and the developed model was implemented using SIMAPRO 7.3. Climate change and acidification were selected as major impact categories as they were considered to be major concerns in mining industry. Although manufacturing stage had a significant impact on all of the environmental parameters, utilization stage was the hotspot for the selected impact categories. The results of this study revealed that belt conveyors have a greater environmental burden in climate change impact category when compared to the trucks. On the other hand, trucks have a greater environmental burden in acidification impact category when compared to the belt conveyors. This study implied that technological improvement in fuel combustion and electricity generation is crucial for the improvement of environmental profiles of off-highway trucks and belt conveyors in the mining industry. The main novelty of this study is that it is the first initiative in applying LCA in the Turkish mining industry.

Findings are higher risk of occupationally conditioned (onychomycosis, obesit arterial hypertension and peptic ulcer of duodenum/stomach) and occupational diseases (neurosensory deafness, radiculopathy, vibration disease) in rock handler drivers. Conclusion was made on necessity to improve prophylaxis and treatment of health disorders in these workers.

The Perceived Consequences of Gold Mining in Postwar El Salvador: A Qualitative Study.

OBJECTIVES: We investigated themes related to the health and environmental impacts of gold mining in El Salvador. METHODS: Over a 1-month period in 2013, we conducted focus groups (n = 32 participants in total) and individual semistructured interviews (n = 11) with community leaders until we achieved thematic saturation. Data collection took place in 4 departments throughout the country. We used a combination of criterion-purposive and snowballing sampling techniques to identify participants. RESULTS: Multiple themes emerged: (1) the fallacy of economic development; (2) critique of mining activities; (3) the creation of mining-related violence, with parallels to El Salvador's civil war; and (4) solutions and alternatives to mining activity. Solutions involved the creation of cooperative microenterprises for sustainable economic growth, political empowerment within communities, and development of local participatory democracies. CONCLUSIONS: Gold mining in El Salvador is perceived as a significant environmental and public health threat. Local solutions may be applicable broadly.

Mining communities from a resilience perspective: managing disturbance and vulnerability in Itabira, Brazil.

This paper applies the resilience lens to a social-ecological system characterized by the presence of large-scale mineral extraction operations. The system in question is the Brazilian community of Itabira, Minas Gerais, host to an iron ore operation of Vale, the world's second largest mining corporation. Utilizing a resilience assessment framework, this study describes the various components of the Itabira social-ecological system revealing the challenges brought about by mining's dominance. Data collection included literature reviews and semi-structured interviews with 29 individuals representing different stakeholder groups. Findings revealed that, despite recent efforts by government to regulate the industry, the mine continues to generate press and pulse disturbances that impact the resilience of the community. Operating from the standpoint that resilience depends largely upon the management capacity of stakeholders, the research identifies three ways to improve mining governance in Itabira. First, there is a need for local government to have more power in dealings with the corporation. Concurrent with this power, however, the municipality must demonstrate ownership over its fate, ideally through the creation of a sustainability plan. Finally, all key parties must demonstrate commitment to cooperating to resolve outstanding disturbances, even when these fall outside the regulatory approval process. While Itabira will remain a mining town for the foreseeable future, actions taken now to address challenges will only strengthen community well-being and sustainability moving forward.

The contributions of human factors and ergonomics to a sustainable minerals industry.

This article describes examples of the application of human factors research and development work to a sustainable minerals industry. It begins by outlining human-related aspects of the minerals industry and the key human factors work previously undertaken in this domain. The focus then switches to sustainability in the minerals industry. Sustainability principles are introduced and illustrations provided of how human factors research and development work fits within such a framework. Three case studies of human factors in the minerals industry research are presented and the sustainability implications in each case study are highlighted. Finally, future trends related to human factors work in a sustainable minerals industry are addressed, in particular the opportunities and possible adverse consequences that increasing deployment of mining automation might bring. PRACTITIONER SUMMARY: Minerals industries are a major global activity with significant sustainability implications. Aspects of sustainability in mining are examined using three case studies. These illustrate the contribution of human factors/ergonomics in reducing risks; developing emergency response management systems; and the value of participatory ergonomics in improving the design of mining equipment.

Occupational noise induced hearing loss in the mining sector in South Africa: Perspectives from occupational health practitioners on how mineworkers are trained.

The aim of this study was to explore the perspectives of occupational health practitioners (OHPs) regarding education and training of mineworkers on occupational noise induced hearing loss (ONIHL) and its impact on mineworkers' health. Qualitative, in-depth telephonic and face-to-face interviews were conducted with 16 OHPs. Purposive and snowball sampling was utilized to recruit participants. Data were analysed using inductive thematic analysis. Three themes emerged from the data: seeing is believing, not my department, barriers and facilitators to raising awareness (with two subthemes -blame it on the language and level of education, and compensation pay-outs). Superficially, OHPs believe that mineworkers are aware of the impact of noise health, however, the OHPs are not knowledgeable on how the mineworkers are educated on ONIHL and its latent consequences. Furthermore, language, low levels of education and literacy, as well as financial constraints are factors found to affect education and training of the mineworkers about the risks of ONIHL. If the mining industry is committed in eliminating ONIHL, they should prioritize health literacy, and mines need to have an effective awareness raising plan in place at every mine. This plan should consider diversity of the workforce, including linguistic as well as educational level diversity.

A Comprehensive Review of Work-Related Musculoskeletal Disorders in the Mining Sector and Scope for Ergonomics Design Interventions.

OCCUPATIONAL APPLICATIONS Work-related Musculoskeletal Disorders (WMSDs) are prevalent in many industries worldwide, including the large and labor-intensive mining sector. A systematic review was carried out to understand problems in the mining sector issues from three broad perspectives: 1) the prevalence of WMSDs among miners; 2) the association of occupational, psychosocial, environmental, and other risk factors with WMSDs causation; and 3) ergonomics interventions already proposed or implemented, and scope for design interventions. Our review revealed that automation, job aids, and displays are methods suitable for ergonomic design interventions. Ergonomic intervention strategies at various hierarchical levels, and the successive way forward as proposed in our review, could act as a catalyst in formulating problem-specific solution strategies by the participation of diverse stakeholders to implement a more human-centric workplace.

TECHNICAL ABSTRACT Background Work-related Musculoskeletal Disorders (WMSDs) are prevalent in the mining sector. While there are numerous factors responsible for the occurrence of WMSDs in this labor-intensive sector, research pertaining to ergonomic design interventions that address various causative factors has not been thoroughly addressed. Purpose We aimed to present an overview of WMSDs in the mining sector, along with plausible intervention strategies in diverse task contexts as suggested by earlier researchers. We also sought to identify the prominent research gaps and propose a way forward to formulate context-specific solutions by involving all stakeholders. Methods Relevant research publications were identified from electronic databases (Google Scholar and ScienceDirect) using appropriate search terms applicable to the mining sector and WMSDs. The literature search was restricted to journal papers, conference proceedings, books, reports, and relevant websites in the English language published between 1990 and 2020. Results Information extracted from the literature review was categorized under three broad topics: 1) the prevalence of WMSDs among miners; 2) associations of psychosocial, occupational, environmental, and other risk factors with WMSDs; and 3) ergonomics interventions in the mining sector. Following the systematic literature review, we outline ergonomics intervention strategies at various levels and provide future research directions to assist all stakeholders in implementing appropriate and context-specific ergonomics design interventions to provide a more human-centric workplace. Conclusions Based on our findings, it is evident that there is an urgent need for formulating and applying job-related ergonomics design intervention plans for occupational safety and well-being of miners in the mining sector.

Malaria prevention and care seeking among gold miners in Guyana.

Despite being a priority population in malaria elimination, there is scant literature on malaria-related behavior among gold miners. This study explores the prevalence and factors influencing malaria prevention, care seeking and treatment behaviors in Guyana gold mining camps. A cross sectional survey was conducted among adult gold miners living in mining camps in the hinterland Regions 1 (Barima-Waini), 7 (Cuyuni-Mazaruni), and 8 (Potaro-Siparuni). Multivariable logistic regressions explored factors associated with miners' self-report of mosquito net use, prompt care-seeking; self-medication; and testing for malaria. A third of miners used a mosquito net the night preceding the survey and net use was higher among those who believed that net use was the norm in their camp (aOR: 3.11; 95% CI:1.65, 5.88). Less than half (45%) of miners had a fever in the past 12 months, among whom 36% sought care promptly, 48% tested positive for malaria while 54% self-medicated before seeking care. Prompt care-seeking was higher among miners with high malaria knowledge (aOR: 1.44; 95% CI: 1.01, 2.05). Similarly, testing rates increased with secondary education (aOR: 1.71; 95% CI: (1.16, 2.51), high malaria knowledge (aOR: 1.45; 95% CI: 1.02, 2.05), positive beliefs regarding malaria transmission, threat, self-diagnosis, testing and treatment, and, trust in government services (aOR: 1.59; 95% CI (1.12, 2.27) and experience of a prior malaria episode (aOR: 2.62; 95% CI: 1.71, 4.00). Self-medication was lower among male miners (aOR: 0. 52; 95% CI: 0.32, 0.86). Malaria prevention and care seeking behaviors among miners are somewhat low and influenced by mosquito net usage, perceived norms, malaria knowledge and prior episode of confirmed malaria. Study findings have implications for malaria interventions in the hinterland regions of Guyana such as the mass and continuous distribution of insecticide treated nets as well as community case management initiatives using trained malaria testing and treatment volunteers to curb malaria transmission among remote gold mining populations. These include efforts to identify and address gaps in distributing mosquito nets to miners and address miners' barriers to prompt care seeking, malaria testing and treatment adherence. Targeted social and behavior change messaging is needed on net acquisition, use and care, prompt care-seeking, malaria testing and treatment adherence. Additional efforts to ensure the overall sustainability of the community case management initiative include increased publicity of the community case management initiative among miners, use of incentives to promote retention rates among the community case management volunteer testers and public private partnerships between the Guyana Ministry of Health and relevant mining organizations.

Assessing the evolution of sustainability reporting in the mining sector.

Since the 1990s several large companies have been publishing nonfinancial performance reports. Focusing initially on the physical environment, these reports evolved to consider social relations, as well as data on the firm's economic performance. A few mining companies pioneered this trend, and in the last years some of them incorporated the three dimensions of sustainable development, publishing so-called sustainability reports. This article reviews 31 reports published between 2001 and 2006 by four major mining companies. A set of 62 assessment items organized in six categories (namely context and commitment, management, environmental, social and economic performance, and accessibility and assurance) were selected to guide the review. The items were derived from international literature and recommended best practices, including the Global Reporting Initiative G3 framework. A content analysis was performed using the report as a sampling unit, and using phrases, graphics, or tables containing certain information as data collection units. A basic rating scale (0 or 1) was used for noting the presence or absence of information and a final percentage score was obtained for each report. Results show that there is a clear evolution in report's comprehensiveness and depth. Categories "accessibility and assurance" and "economic performance" featured the lowest scores and do not present a clear evolution trend in the period, whereas categories "context and commitment" and "social performance" presented the best results and regular improvement; the category "environmental performance," despite it not reaching the biggest scores, also featured constant evolution. Description of data measurement techniques, besides more comprehensive third-party verification are the items most in need of improvement.

Those Who Don't Return: Improving Efforts to Address Tuberculosis Among Former Miners in Southern Africa.

Despite increasing awareness regarding the role of oscillating migration in the mining industry as a major driving force in the spread of tuberculosis (TB) throughout southern Africa, very little work has focused on the historical and contextual factors which may contribute to former migrant miners' present-day risk of TB. Most research regarding migration-related and occupational influences on TB has been done on current miners still employed by the mining industry. Through both a historical and contemporary lens, this paper explores and elucidates the need to address the TB epidemic among former migrant mine workers and provides considerations to improve current interventions among this critical population.

Occupational injury burden among gold miners in Ghana.

The mining environment is particularly dangerous in low- and middle-income countries. We sought to better understand the burden, characteristics and risk factors associated with gold mining, through a household survey of 1,029 miners in four districts, in Ghana. We found a high burden of injuries, with 25.5% of workers injured in the past year, giving an incidence of 19.67 injuries per 200,000 hours worked. Notably, an increase in injury risk was associated with work in the informal mining sector (galamsey), with an adjusted injury incidence ratio of 1.57 (95%CI: 1.12, 2.19) compared with miners in the formal sector. Half of gold miners in Ghana work in galamasey, and this sector is a high priority for safety promotion. Improving the safety of the equipment, which accounted for nearly half (46.2%) of galamsey-related injuries, could be a prime target for improving safety.

Using the Framework for Health Promotion Action to address staff perceptions of occupational health and safety at a fly-in/fly-out mine in north-west Queensland.

ISSUE ADDRESSED: An exploratory descriptive study was undertaken to identify staff perceptions of the types and sources of occupational health and safety hazards at a remote fly-in-fly-out minerals extraction and processing plant in northwest Queensland. METHODS: Ongoing focus groups with all sectors of the operation were conducted concurrently with quantitative research studies from 2001 to 2005. Action research processes were used with management and staff to develop responses to identified issues. RESULTS: Staff identified and generated solutions to the core themes of: health and safety policies and procedures; chemical exposures; hydration and fatigue. The Framework for Health Promotion Action was applied to ensure a comprehensive and holistic response to identified issues. CONCLUSIONS: Participatory processes using an action research framework enabled a deep understanding of staff perceptions of occupational health and safety hazards in this setting. The Framework for Health Promotion provided a relevant and useful tool to engage with staff and develop solutions to perceived occupational health and safety issues in the workplace.

Effects of human and organizational deficiencies on workers' safety behavior at a mining site in Iran.

OBJECTIVES: Throughout the world, mines are dangerous workplaces with high accident rates. According to the Statistical Center of Iran, the number of occupational accidents in Iranian mines has increased in recent years. This study investigated and analyzed the human and organizational deficiencies that influenced Iranian mining accidents. METHODS: In this study, the data associated with 305 mining accidents were analyzed using a systems analysis approach to identify critical deficiencies in organizational influences, unsafe supervision, preconditions for unsafe acts, and workers' unsafe acts. Partial least square structural equation modeling (PLS-SEM) was utilized to model the interactions among these deficiencies. RESULTS: Organizational deficiencies had a direct positive effect on workers' violations (path coefficient, 0.16) and workers' errors (path coefficient, 0.23). The effect of unsafe supervision on workers' violations and workers' errors was also significant, with path coefficients of 0.14 and 0.20, respectively. Likewise, preconditions for unsafe acts had a significant effect on both workers' violations (path coefficient, 0.16) and workers' errors (path coefficient, 0.21). Moreover, organizational deficiencies had an indirect positive effect on workers' unsafe acts, mediated by unsafe supervision and preconditions for unsafe acts. Among the variables examined in the current study, organizational influences had the strongest impact on workers' unsafe acts. CONCLUSIONS: Organizational deficiencies were found to be the main cause of accidents in the mining sector, as they affected all other aspects of system safety. In order to prevent occupational accidents, organizational deficiencies should be modified first.

Ending on a positive: Examining the role of safety leadership decisions, behaviours and actions in a safety critical situation.

Safety leadership is an important factor in supporting safe performance in the workplace. The present case study examined the role of safety leadership during the Bingham Canyon Mine high-wall failure, a significant mining incident in which no fatalities or injuries were incurred. The Critical Decision Method (CDM) was used in conjunction with a self-reporting approach to examine safety leadership in terms of decisions, behaviours and actions that contributed to the incidents' safe outcome. Mapping the analysis onto Rasmussen's Risk Management Framework (Rasmussen, 1997), the findings demonstrate clear links between safety leadership decisions, and emergent behaviours and actions across the work system. Communication and engagement based decisions featured most prominently, and were linked to different leadership practices across the work system. Further, a core sub-set of CDM decision elements were linked to the open flow and exchange of information across the work system, which was critical to supporting the safe outcome. The findings provide practical implications for the development of safety leadership capability to support safety within the mining industry.

Reducing non-contact electric arc injuries: an investigation of behavioral and organizational issues.

PROBLEM: It is estimated that 5 to 10 arc flash explosions occur in electric equipment every day in the United States. In the mining industry the largest single injury category of electrical injuries are caused by non-contact electrical arcs. METHOD: This investigation progressed in two phases: (a) 836 Mine Safety and Health Administration (MSHA) reports of electric arcing incidents that occurred over a period of 11 years were reviewed, and (b) personal interviews were conducted with 32 individuals. A theoretical Safe Job Performance Model guided the study. RESULTS: Behavioral dimensions were identified and included the effect of worker experience, judgment and decision-making ability, behavioral and organizational controls, and safety culture. SUMMARY: The National Institute for Occupational Safety and Health (NIOSH) conducted an investigation of behavioral components associated with arc flash incidents and developed recommendations for interventions based on findings. IMPACT ON INDUSTRY: This study fills a vacuum in electrical training with a focus on the organizational and behavioral aspects of arc flash incidents. The research is cross-cutting in its scope, in that the results apply not only to mining and construction, but many other industries employing electricians. Although the majority of mine electrical injuries are the results of burns from electrical arcs, few miners are aware that such a hazard exists. A safety training program, which includes a video and an instructor's discussion guide, was developed for electricians based on this study's findings. "Arc Flash Awareness" was released in 2007 (DHHS NIOSH Publication No.2007-116D) and is available through 1-800 CDC INFO. Phone: 1-800 232-4636 or email cdcinfo@cdc.gov. It is also available from MSHA at MSHADistribution@dol.gov or 304-256-3257 (DVD-576). Private industry is producing Portuguese and Spanish language translations.

Estrategia multimodal para la prevención de COVID-19, en una faena minera / Multimodal strategy for the prevention of COVID 19 in a mining site

INTRODUCCIÓN: Al inicio de la pandemia de COVID-19, las empresas mineras, debieron implementar sistemas de gestión para prevenir transmisión de SARS-CoV-2. OBJETIVO: Describir los resultados iniciales de la estrategia multimodal para la prevención de COVID-19, en una faena minera. MATERIALES Y MÉTODOS: Estudio descriptivo, de corte transversal. Se estructuró un sistema de gestión que consideró medidas administrativas, ambientales, tamizaje de riesgos y gestión de casos de riesgo al interior de la empresa. Análisis de datos con estadística descriptiva. RESULTADOS: Las medidas administrativas se tradujeron en que 8.116 (34%) trabajadores de la faena fueron suspendidos de sus labores habituales. El tamizaje de riesgo antes del ingreso a la faena identificó 450 casos sospechosos que fueron derivados a su domicilio. En el procedimiento de gestión de casos 1.073 personas fueron clasificadas en algunos de los grupos de riesgo. Se detectaron 10 casos de trabajadores con RPC positiva, siendo que 50% fue asintomático; en los sintomáticos, los síntomas más frecuentes fueron: tos (60%) y cefalea (40%). CONCLUSIONES: Estos resultados, dan luces sobre la importancia de implementar una estrategia multimodal, adaptada a la realidad local de una empresa de la gran minería, para prevenir la transmisión de SARS-CoV-2.

BACKGROUND: Mining companies must implement management systems dedicated to health and safety at work to prevent the transmission of SARS-CoV-2 among their workers, however, the literature on this is scarce. AIM: To describe a multimodal strategy for the management of health and safety at work, to address the risk of COVID-19 in large mining. METHODS: Descriptive cross-sectional study, carried out in a large mining company. A management system was structured that considered administrative measures, of an environmental nature, risk screening, and management of risk cases within the company. The data analysis was done using descriptive statistics. RESULTS: The administrative measures resulted in 8,116 (34%) workers at the site being suspended from their usual work. Risk screening before entering the site identified 450 suspected cases that were referred to their home. In the case management procedure, 1,073 people were classified in some of the risk groups. 10 cases of workers with PCR were detected in the follow-up period. Environmental measures were not very sensitive. CONCLUSIONS: These results shed light on the importance of implementing a multimodal strategy, adapted to the local reality, in preventing the spread of SARS-CoV-2 in the period under study, at the mining site intervened.
