摘　　要：针对盛泰煤矿15203工作面回采期间因粉尘浓度高严重制约着工作面安全高效回采的情况,提出对工作面采取长孔低压以及短孔中压联合注水工艺技术措施。通过实际应用效果来看,采取联合注水工艺后,实现了煤层减尘的目的,工作面后期回采期间粉尘质量浓度降低至23 mg/m^(3),取得了显著应用成效。During the mining period of the 15203 working face,the high dust concentration seriously restricts the safe and efficient mining of the working face.Based on this,the 15203 working face of Shengtai Coal Mine is taken as the research object,and a combination of long hole low pressure and short hole medium pressure water injection process is adopted for the working face.From the actual application results,it can be seen that after adopting the combined water injection process,the goal of reducing coal seam dust has been achieved.During the later mining period of the working face,the dust concentration has been reduced to 23 mg/m^(3),achieving significant application results.
