煤矿井下粉尘作业工人脱离粉尘(简称脱尘)后,经检查被确诊为煤矽肺新发病例者,称晚发性煤矽肺(简称晚发煤矽肺)。在坊子煤矿煤矽肺动态观察中,发现1981年比1972年晚发煤矽肺病人增加了4.64倍。为进一步了解其发生、发展的特点和规律,为修改尘肺医疗预防措施,加强医学观察和防治提供依据,我们于1982年对该矿晚发煤矽肺进行了流行病学调查分析,现报告如下:
Coal mine dust workers from the dust (referred to as dust), the examination was diagnosed as new cases of coal silicosis, said late onset of coal silicosis (referred to as late coal silicosis). During the dynamic observation of coal silicosis in Fangzi Coal Mine, it was found that the number of patients with coal silicosis increased by 4.64 times in 1981 than in 1972. In order to further understand the characteristics and laws of their occurrence and development, and to provide evidences for the revision of pneumoconiosis preventive measures and strengthening medical observation and prevention, we conducted an epidemiological investigation and analysis of the late-onset coal silicosis in 1982 and are reported as follows:
