通过对某煤矿２９５名综采工与同期１８４名普采工、８４名炮采工１８年对照观察，煤工尘肺累积患病率分别为５５‰、４９．２‰、２８４．６‰，三者比较差别不显著（Ｐ＞０．０５），但都已超过国内连续工作３０年患病率控制在１０‰以下的目标。综采工中的采煤司机、放顶煤工、支架工、清理工、进回风巷支护工是重点保护人群，采煤机、放顶煤、支架是重点防降尘作业。采取下列三项措施可有效控制综采工煤工尘肺患病：①采煤前先行浅壁煤层注水，采煤时抑尘器喷雾。②工人佩戴防尘口罩。③定期互换工作面内和进风巷内工人作业岗位
Through the observation of 295 full-mechanized mining and 184 general mining and 84 artillery mining in a certain coal mine for 18 years, the cumulative prevalence of pneumoconiosis in coal mines was 55 ‰, 49.2 ‰ and 284.6 ‰, respectively The difference was not significant (P> 0.05), but all exceeded the 30-year prevalence rate of continuous work in China below 10%. Comprehensive mining in the coal drivers, caving workers, scaffolding workers, cleaning workers, airbags back into the airway protection is a key protection of the crowd, shearer, caving, stents is the focus of anti-dust operations. Take the following three measures can effectively control the comprehensive mining coal workers pneumoconiosis: ① mining before the shallow-wall coal water injection, coal dust suppression spray. ② workers wear dust masks. ③ regular exchange of work surface and airway workers inside the work position
