民营及国营煤矿工人职业病及危害因素分析

Analysis of the occupational diseases and risk factor of the workers in state--owned and private coal mine

目的：调查本地区国营及民营煤矿工人的健康状况,为进一步职业健康监护工作提供依据.方法：选择本市及邻市具有代表性的14家煤矿,分别国营7家,民营7家,比较2类煤矿的工作环境有害因素、工人职业健康状况.结果：民营煤矿尘肺检出率明显高于国营煤矿,差异具有统计学意义,P〈0.05;民营煤矿工作环境平均粉尘浓度明显高于国营煤矿,差异具有统计学意义,P〈0.05;国营煤矿与民营煤矿的游离SiO2浓度的差异没有统计学意义,P〉0.05.国营煤矿工作环境明显比民营煤矿条件好.结论：尘肺是威胁煤矿工人健康的主要职业病,尤其民营煤矿.

Objective：To investigate the healthy state of the workers in the state--owned and private coal mines in order to further provide the basis for the surveillance of occupational health. Methods：We choosed 14 representative coal in the city and the neighboring city. 7 cases were state-- owned. 7 cases were private. To compare the risk factors in the working environment and the healthy state of the workers in the 2 types of coal mines. Results,The detection rate of pneumoconiosis in the private coal mine was higher than the state--owned coal mines. The difference was statistically significant,P〈0. 05. The The average concentration of coal dust in the working environment of private coal mines was higher than the state--owned coal mines. The difference was statistically significant, P〈0.05. The concentration of free SiO2 in the state--owned and private coal mine was not statistically difference, P〉0.05. The working environment of the state--owned coal mines was better than private coal mine. Conclusion ： Pneumoconiosis was a major occupational diseases that threated the workers of coal mine. It was in the private coal mines especially.
