Objective@#To investigate the prevalence and influencing factors of lower respiratory tract disease.@*Methods@#The health physical examination data of 4000 coal dust exposed workers who had physical examination in the Institute of Occupational Disease Prevention and Treatment in 2016 were collected and analyzed with SPSS 20.0 software.@*Results@#Out of the 4000 coal workers, the Prevalence rate of pulmonary tuberculosis, chronic bronchitis, CWP were 1.00% (40/4000) , 0.63% (25/4000) , 0.43% (17/4000) . 17 coal workers suffered from coal workers. The prevalence of workers both exposed to silicon and coal dust was 1.15% (2/174) , which was higher than that of other the job type. The prevalence of CWP among age groups, length of service and occupational category were found significant difference (P<0.05) , raising with the increase of duration of dust exposure and age increasing (χ2trend=17.171, 5.344, P<0.05) . The prevalence of emphysema and chronic bronchitis between different working years and different ages are all statistically significant (P<0.05) , increasing with duration of dust exposure (χ2trend=9.906, 10.118, P<0.05) .@*Conclusion@#The prevalence rate of CWP is not high, and closely related with duration of dust exposure and dust species. The prevalence of lower respiratory tract disease is higher in the tunneling and mining workers and raising with the duration of dust exposure.
