目的探讨煤矿企业尘肺病未来发病趋势。方法以铁法煤业集团所属8个煤矿所有接尘时间>1 a的矿工为调查对象,根据接尘矿工尘肺病年平均发病率和同地区男性居民年龄别预期寿命,预测迄今未患尘肺病矿工在预期寿命内可能发病的人数。结果共调查尘肺患者236人,未患尘肺矿工15 918人,迄今仍存活的未患煤工尘肺矿工有15 390人,预测将有77人罹患尘肺;其中1958—1968年开始接尘的煤矿工人占多数,约41人,发病率为4.9%。按工种计,掘进工可能有66人罹患尘肺病,占总发病人数的85.1%;未来20年内煤矿工人尘肺病新发病例约67人。结论铁法煤业集团接尘矿工未来仍有人罹患尘肺病,但随时间推移有逐年下降趋势。
Objective To explore the future trend of pneumoconiosis in coal mining enterprises. Methods According to the average annual incidence of pneumoconiosis in dust miners and the age-specific life expectancy of male inhabitants in the same coal mine in Tiefa Coal Industry Group, The number of miners who may have an illness during their life expectancy. Results A total of 236 pneumoconiosis patients, 15 918 non-pneumoconiosis miners and 15 390 survivors without coal workers were surveyed. A total of 77 pneumoconiosis patients were estimated to have pneumoconiosis. Among them, mine workers who started to dust in 1958-1968 Accounting for the majority, about 41 people, the incidence was 4.9%. In terms of types of work, there may be 66 people suffering from pneumoconiosis, accounting for 85.1% of the total number of tunneling workers. In the next 20 years, there are about 67 new cases of pneumoconiosis among coal miners. Conclusion Tiefei Coal Industry dust miner in the future still have pneumoconiosis, but over time declined year by year.
