摘　　要：针对松软突出煤层瓦斯抽放钻孔施工深度浅、成孔率低等难题,通过优选施工钻具,改进排渣方式和适当的技术参数入手,提高了钻进深度,成孔率大幅度提高,取得了较好的效果。For the problems of shallow depth of the boreholes construction and low hole - making rate of gas drainage boreholes in soft outburst coal seam, through optimizing construction drilling tools, improving slag discharge ways, starting with appropriate technology parameters, the drilling depth is improved, the hole- making rate is greatly enhanced, and good results have been achieved.
