本文应用寿命表法分析采煤工煤肺发病情况,工龄29年者发病率高达37.4%,且随着工龄的延续,接尘量的增加,煤肺发病还将逐年递增。推算同龄同代同时入矿接尘的健康工人,在当前粉尘等条件下可望工作25年左右。井下接尘工人平均发病工龄为9.9年。提出采煤工每3~5年检查一次的间隔年限。为煤矿轮换工制提出每5年轮换一次是可行的。
In this paper, the life table method was used to analyze the incidence of coal-mining lung in coal miners. The incidence of 29 years of service was as high as 37.4%. With the extension of working life and the increase of dust-holding capacity, the incidence of coal-lung disease will also increase year by year. It is estimated that under the current conditions of dust and other health workers expected to work at the same age with dust in the same age is expected to work for about 25 years. Underground workers exposed to dust the average age of 9.9 years. Proposed coal workers every 3 to 5 years to check the interval of years. It is feasible for the coal rotation system to rotate once every five years.
