近几年来煤矿矽肺发病有增快趋势。为摸清县办小煤矿接尘人员煤矽肺的发病情况,我们对某县四个小煤矿进行了煤矽肺发病的调查。现报告如下: 我们对1981年底以前参加工作的接尘者和接尘三年调离者(包括退休职工)以及现有0-Ⅰ和各期煤矽肺者,检查内科、五官科,拍摄X线胸片和进行卫生学调查。四个矿为国营县办煤矿,职工1225人,接尘人员992人,应检911人,实检866人,受检率95.01％。
In recent years, the incidence of silicosis in coal mines has been accelerating. In order to find out the incidence of coal silicosis among dust collectors of small coal mines in the county, we investigated the incidence of coal silicosis in four small coal mines in a county. We report the following: We conducted a survey of internal medicine, ENT and X-ray imaging of persons who took part in the work before the end of 1981 and those who had been demobilized for three years (including retired staff) and the existing 0-I and various stages of coal- Chest radiograph and hygiene survey. The four mines are coal mines operated by state-owned counties and have 1,225 workers and 992 persons receiving dust. 911 people should be inspected, 866 people should be inspected, and the rate of detection should be 95.01%.
