本文报道了全国电力系统1989年尘肺流行病学调查结果。尘肺现患率和累积患病率、病死率分别为2.41％和3.05％。21.64％。电力系统尘肺病例主要集中分布于水电施工企业(71.33％),其次是火电生产企业(27.76％)。电力系统已发生的各种尘肺中,有82.99％为矽肺,8.99％为煤工尘肺。已发生尘肺的24个统计工种中,水电施工凿岩工尘肺病例占总例数的60.25％,火电厂锅炉检修运行工和输煤工分别占8.79％和6.45％。并对电力系统尘肺异常分布的原因、规律及防治重点进行了分析讨论。

EPIDEMIOLOGICAL STUDY ON PNEUMOCONIOSIS IN POWER INDUSTRY

The epidemiological investigation on pneumoconiosis was carried out nation widely power industry in 1989.The result showed that the prevalence,cumulative incidence and mortality from pneumoconiosis were 2.41%, 3.05% and 21.64% respectively. The cases were mainly distributed in hydroelectric construction enterprises (71.33%) , second to thermal power plants (27.76%) . There were 8 categories of pneumoconiosis in the diagnosed cases, of which silicosis was 82.99% and coal workers' pneumocoaiosis was 8.99%. In 24 types of dust exposed jous, 60.25% of the total cases appeared among the rock drillers' pneumoconiosis, the boiler overhaulers and the workers conveying coal occupied 8.79% and 6.45% respectively, The reason of differential distribution, the regularity and the prevention priority in power industry were discussed .
