自1963年国家颁布了矽肺诊断分期标准(以下简称“我国分期”)以来,各地煤矿参照“我国分期”在煤矿尘肺的诊断方面做了不少的工作。鉴于尘肺的诊断涉及到煤矿尘肺防治的各个方面,为使各地区的观察材料具有可比性,就必须对尘肺的诊断标准一致, Since 1963, the state has promulgated the silicosis staging standard (hereinafter referred to as “China’s staging”), various coal mines have done a lot of work in the diagnosis of coal mine pneumoconiosis with reference to “China’s staging.” Since the diagnosis of pneumoconiosis involves all aspects of pneumoconiosis prevention and control in coal mines, in order to make the observational materials of all regions comparable, the diagnostic criteria of pneumoconiosis must be consistent,
