摘要
本研究对8个煤矿、两个选煤厂和一个煤炭装卸作业区进行劳动卫生、流行病学调查.煤尘浓度为10.2～200.0mg/m^3,煤尘中游离SiO_2为2.4～7.3％.检查了6,373名煤尘作业工人,煤肺患病率为0.26～15.2％,慢性支气管炎患病率为21.9～36.9％,肺气肿为11.8％.18例煤尘作业的尸检病例中,17例有慢性支气管炎改变,16例有肺气肿.结果提示,在防治煤尘危害时,除应注意煤肺外,还应对煤工的慢支和肺气肿给予足够的重视.
Environmental and epidemiological investigations were conducted in 8 coal mines, 2 coal-dressing plants and a coal loading area. The concentrations of coal dust were 10.2-200.0mg/m3.The contents of free silica were 2.4-7.3%. Among 6373 coal workers, the prevalences of anthracosis, chronic bronchitis and emphysema amounted to 0.26-15.2%, 21.9-36.9% and 11.8% respectively. Among 18 dead cases on whom autopsy was performed, 17 cases presented pathological changes of chronic broachitis, 16 cases emphsema. The results suggest that more attention should be paid to coal workers' chronic bronchitis and emphysema as well as anthracosis.
