八个煤矿的现场调查分析表明,六十年代以来逐步推行的湿式作业,综合防尘,使我国的煤矿尘肺防制收到一定效果。两类尘肺的发病率都呈下降趋势。但结合各煤矿的粉尘浓度资料说明,有些煤矿的尘肺防制效果还不够理想,至今尘肺的发病仍很严重,近年的尘肺病例数呈一种有增无减的状况。
Field investigation and analysis of eight coal mines shows that the wet operation gradually implemented since the 1960s and integrated dust prevention have made some achievements in the prevention and control of pneumoconiosis in coal mines in China. The incidence of both types of pneumoconiosis showed a downward trend. However, with the dust concentration data of the coal mines, some coal mines have not achieved the desired effect of controlling pneumoconiosis. Up to now, the incidence of pneumoconiosis is still very serious. The number of pneumoconiosis cases in recent years shows an increasing status.
