摘　　要：针对倾斜薄煤层切顶卸压无煤柱沿空留巷围岩控制的问题,运用理论分析和现场实测相结合的方法,介绍了0457(K24)回采工作面和巷道的概况,分析了切顶卸压爆破技术的基本原理。根据现场0457(K24)工作面机巷的实际情况,提出了采用切顶卸压爆破沿空留巷技术,确定了切顶卸压爆破的技术参数。Based on the problem of surrounding rock control of gob-side entry retaining of cut the top and pressure relief without coal pillar of inclined thin coal seam, No. 0457 （K24） working-face and roadway was analyzed, and the basic principle of roof breaking and pressure releasing blasting by adopted the method of combining the theory analysis and the test of practice. Departures from the practice of the conveyor roadway of the No. 0457（K24） working-face, then the technology of roof breaking and pressure releasing blasting at god-side entry retaining was introduced, and the parameters of this technology is established.

关 键 词：薄煤层 预裂爆破 巷道变形
