本文对四川省煤炭系统1986年底前诊断的尘肺病例进行了调查分析,结果表明该系统30326例尘肺病例中煤工尘肺占82.19%,矽肺占17.75%。主要分布在重庆、内江、万县、乐山等市地,占总例数的86.17%,工种以纯掘、主掘、纯采、主采、混合为主,平均发病年龄、发病工龄和死亡年龄随年代推移而延长,结核合并率、煤工尘肺晋期率随年代推移而降低,县属企业尘肺检出率、1986年现患率均高于县以上企业(P<0.05)。 In this paper, the investigation and analysis of the pneumoconiosis diagnosed in Sichuan Province before the end of 1986 showed that in the 30,326 cases of pneumoconiosis, coal worker’s pneumoconiosis accounted for 82.19% and silicosis accounted for 17.75%. Mainly distributed in Chongqing, Neijiang, Wanxian, Leshan and other cities, accounting for 86.17% of the total number of cases. The main types of work were excavation, main digging, pure mining, main mining and mixing, and the average age of onset, the length of service and the age of death The rate of tuberculosis consolidation and the rate of pneumoconiosis in coal workers decreased with the passage of time. The detection rate of pneumoconiosis in county-owned enterprises was higher in 1986 than in those above the county level (P <0.05).
