作者等对苏联煤矿5年来93例矿工尘肺发病率进行了分析研究。发现矿工尘肺发病率与煤尘形成的过程和煤尘的比重、湿度,煤尘发生的成熟程度密切相关,特别是后者对矿工尘肺发病率的影响尤为显著。无烟煤矿矿工尘肺发病率高于其它煤矿2～6 The authors analyzed the incidence of pneumoconiosis among 93 miners in Soviet coal mines over the past five years. Found that the incidence of pneumoconiosis miners and coal dust formation process and the proportion of coal dust, humidity, the degree of maturity of coal dust are closely related, especially the latter on the incidence of pneumoconiosis miner particularly significant. Anthracite miner pneumoconiosis incidence rate higher than other coal mines 2 ~ 6
