摘　　要：以店坪煤矿9#煤层9-100工作面开采为工程实例,为提高采出率,拟在该工作面回风巷应用切顶卸压无煤柱护巷技术;通过理论计算与实践分析,确定了切顶卸压技术的关键参数;实践表明,护巷达到预期效果,经济效益增收显著。Taking the mining of 9-100 working face of 9#coal seam in Dianping Colliery as an engineering example,in order to improve the recovery rate,it is planned to apply the roof-cutting pressure relief and no pillar roadway protection technology in the return airway of this working face.The key parameters of roof-cutting pressure relief technology are determined through theoretical calculation and practical analysis,which achieves the expected results of the roadway protection and has significant economic benefits.

关 键 词：无煤柱开采 护巷技术 切顶卸压 沿空留巷
