摘　　要：为了增加二1煤层透气性,提高抽放效果,对不具备保护层开采的地点,采用底板穿层钻孔深孔聚能爆破增透试验方法,对增加二1煤层透气性、提高抽放效率进行了应用研究。试验结果表明:采用底板穿层钻孔深孔聚能爆破增透技术可行,抽放效果明显。对不具备保护层开采的地点进行二1煤层消突工作具有重要的指导意义。In order to increase the permeability of Ⅱ1 coal seam,enhance the gas drainage effects,Cuimiao Coal Mine made deep-hole cumulative blasting permeability-increased experiments in bores through rock and coal seam at Ⅱ1 coal seam without protective seam, application research also was made on the inprovement of permeability of Ⅱ1 coal seam and drainage efficiency. Through the experiment, the method shows to be feasible, significant for eliminating coal and gas outburst accident of Ⅱ1 coal seam. All this have important gnilding value for outburst prevention of Ⅱ1 coal seam without protective seam.
