在历年死亡的496例尘肺中(矽肺120例,煤矽376例),以金属矿山和煤矿井下作业的尘肺死亡者居多。矽肺和煤矽肺全死因死亡构成比,肺心病死亡占首位,肺癌死亡占第二位,其次是咯血、肺性脑病、肺结核。矽肺和煤矽肺的肺心病死亡分别为44.2％和55.6％,且随病期进展合并肺心病死亡率递增。肺癌死亡者中,矽肺占15.0％,煤矽肺占
Among the 496 cases of pneumoconiosis (120 cases of silicosis and 376 cases of coal and silicon) who died in the past years, the majority of pneumoconiosis workers who worked in metal mines and coal mines were the majority. Silicosis and coal-silicosis all-cause mortality ratio, pulmonary heart disease deaths accounted for the first place, lung cancer deaths accounted for second, followed by hemoptysis, pulmonary encephalopathy, tuberculosis. The death rates of pulmonary heart disease in silicosis and coal silicosis were 44.2% and 55.6% respectively, and the mortality rate of pulmonary heart disease was increased with the progression of disease. Among lung cancer deaths, silicosis accounted for 15.0% and coal silicosis accounted for
