煤尘肺是由于长期吸入含游离二氧化硅煤尘所发生的尘肺。一般常以煤矿采煤工作面的采煤工、装煤工等多见,而城区煤基生产厂的作业工人中的煤工尘肺却往往易被忽视。为此我们开展了这项针对城区煤基生产厂的煤尘肺发病的调查。资料收集1.47例从事煤基生产的工人,其中男性22例,女性25例,年龄为27～65岁。检查资料由拍片体检获得,拍片结果由南京市尘肺病诊断小组提供。2.作业点分别取自拌料点和打煤基点,粉尘浓度为1989年～1991年连续3年监测的平均浓度。
Coal pneumoconiosis is the result of prolonged inhalation of pneumoconiosis occurring with free silica dust. Commonly used coal mining face coal miners, coal miners and other more common, and urban coal-based production plant workers in the coal workers pneumoconiosis is often easily overlooked. To this end, we conducted a survey of the coal-based manufacturing plant in urban areas of the incidence of pneumoconiosis. Data collection 1.47 workers engaged in coal-based production, including 22 males and 25 females, aged 27 to 65 years old. Inspection data obtained by the film examination, filming results from the Nanjing pneumoconiosis diagnosis team. 2. The operating points were taken from the mixing point and coal-based point, the dust concentration for the 1989 to 1991 for 3 consecutive years of monitoring the average concentration.
