煤田地质与煤矿尘肺的流行病学研究

Epidemiological Study of Geology of Coal Field and Coalworkers' Pneumoconiosis,

通过对八个煤矿煤田地质劳动卫生学调查及煤矿尘肺的流行病学分析,利用煤田地质因素有关指标,设计出围岩地质因素危害指数和煤层地质因素危害指数。应用这些指数有利于对不同性质的粉尘,按其危害性强度或其实际危害的程度进行分级管理,以提高防治工作水平和经济效益。对新开煤田尘肺流行预测也有实际意义。

Field epidemiological survey was carried out in eight coalmines scatteringall over the country.By use of indicies related to geological factors,harmful indicies of rock and coal seam geology were designed.Classfy controls can be employed according to the degree of harmfulness and guantities of dusts given by such indicies,so that better financial and preven-tive effects can be reached.
