【摘要】：目的分析山东省某煤矿工作场所职业病危害现况和作业人员健康检查状况,为其职业病防治工作提供依据。方法 2011-2014年连续4年对该矿进行职业卫生现场调查,并对工作场所职业危害因素检测结果及2011年和2013年工人健康体检结果进行分析。结果该矿118个定点采样和139个个体采样检测显示煤尘定点采样最大超限倍数为7.7倍,个体检测时间加权平均浓度(Concentration-Time Weighted Average,CTWA)最大值达5.11 mg/m3,均超于国家标准限值;噪声作业岗位定点采样检测显示,达标率为52.9%,而超标最严重的是打眼工岗位。手传振动检测结果是打眼工接振强度(8.2 m/s2)均超过职业接触限值5 m/s2。毒物检测结果均符合职业接触限值要求,合格率为100%。2011年和2013年健康体检结果显示,工人电测听异常率有升高。结论粉尘和噪声是该煤矿主要的职业病危害因素,煤矿采取的职业病危害防护设施及措施基本可行,但职业病危害仍然存在。
[Abstract]:Objective to analyze the present situation of occupational disease hazards and health examination of workers in a coal mine in Shandong Province, and to provide evidence for the prevention and treatment of occupational diseases. Methods the occupational health survey was carried out in the mine for 4 consecutive years from 2011 to 2014, and the results of occupational hazard factors in the workplace and the health examination results of workers in 2011 and 2013 were analyzed. Results 118 fixed-point sampling and 139 individual sampling in this mine showed that the maximum excess multiple of coal dust sampling at fixed point was 7.7 times, and the maximum value of Concentration-Time weighted average CTWAs was 5.11 mg / m ~ (3), which was higher than the national standard limit. The fixed point sampling and detection of noise job shows that the rate of reaching the standard is 52.9, and the most serious problem is the position of eye striking. The results showed that the vibration intensity was 8.2 m / s ~ (2), which exceeded the occupational exposure limit of 5 m / s ~ (2). The results of health examination showed that the abnormal rate of electrical audiometry of workers was increased. Conclusion Dust and noise are the main occupational hazard factors in this coal mine. The protective facilities and measures adopted in the coal mine are basically feasible, but the occupational hazards still exist.
