Abstract
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.关键词
