尘肺病是煤矿开采中一个十分重要的问题.在五十年代初,一般认为煤矿工人所得的尘肺,是由于长期吸入含矽量高的粉尘所致.但后来国内外一些学者通过对某些地区煤矿的研究,发现粉尘中有的含矽量非常低,而尘肺发病率却很高,与传统的理论有很大的差异.例如青山煤矿的煤尘中虽然含矽量比较低,但尘肺发病率却很高,远远超过了接触矽尘作业工人的发病率、平均发病期也比高坑、安源两矿的岩巷掘进工人短3～5年,这就是一个很好的证明.为了弄清这个问题,最近,我们根据青山矿在含无烟
Pneumoconiosis is a very important issue in coal mining. In the early 1950s, it was generally considered that pneumoconiosis derived from coal miners was due to the long-term inhalation of dust containing high amounts of silicon. However, some scholars at home and abroad later passed the investigation on some areas In coal mines, it is found that there is a very low content of silicon in dust and a very high incidence of pneumoconiosis, which is quite different from the traditional theory. For example, although coal dust in Qingshan Coal Mine is relatively low, the incidence of pneumoconiosis The rate is very high, far exceeding the incidence of workers exposed to silica dust, the average duration of disease is also shorter than the high pit, Anyuan two mine tunneling workers short 3 to 5 years, this is a good proof. Clearly understand this issue, recently, we are based on the Castle Peak mine containing smoke-free
