摘　　要：粉尘是煤矿最严重的职业危害因素。随着煤炭开采技术的不断进步,回采工作面粉尘危害的严重性也日益加剧。对粉尘进行日常检测时常会因为采样点的不同而导致检测结果不同,从而影响工作面的粉尘防治。因此明确回采工作面粉尘检测点对于粉尘检测有着重要的作用。通过对同一作业点不同位置呼尘/个体的比率分析找到稳定点,再结合回风巷粉尘浓度趋势图,从而得到了回采工作面粉尘检测点。Dust is the most serious occupational hazard factors in coal mine. With the constant progress of coal mining technology, the seriousness of the working face dust hazard is also growing. The dust routine testing often obtains different test results caused by different sample point, which affects working face dust control. So the specific working face dust testing point plays an important role in dust detection. To find the stable point based on different locations on the same operating point breathe dust/individual ratio analysis, and coupled with return air roadway dust concentration trend diagram, finally working face dust testing point have been obtained.
