摘　　要：为解决N101工作面粉尘浓度高,严重污染作业环境的问题,根据煤层注水减尘机理和工作面实际地质条件,通过理论计算和现场试验,设计煤层动压注水参数,对煤层采取深孔动压注水措施,并对注水前后粉尘浓度进行对比,在工作面采取动压注水措施后粉尘的平均浓度下降75.2%,呼吸性粉尘的平均浓度下降70.9%,工作面作业环境得到改善。To solve the problems of high dust concentration and serious pollution of working environment at N101 face,according to the coal seam water injection and dust reduction mechanism and the actual geological conditions of the working face,through theoretical calculations and field tests,the article designs coal seam dynamic pressure water injection parameters,adopts deep-hole dynamic pressure water injection measures to the coal seam,and compares the dust concentration before and after water injection.After adopting dynamic pressure water injection measures at the working face,the average dust concentration drops by 75.2%,the average concentration of respirable dust has dropped by 70.9%,which improves the working environment of the working face.
