本文通过对广西统配煤矿井下粉尘卫生学调查发现,矿井因生产煤种不同尘肺患病程度有很大差异。烟煤矿井的患病率高于褐煤矿井的患病率。 In this paper, we investigate the underground dust hygiene survey of coal mines in Guangxi. It is found that there are great differences in the degree of pneumoconiosis due to different types of coal dust in coal mines. The prevalence of bituminous coal mines is higher than that of lignite mines.
