摘　　要：为解决沿空留巷开采技术对工作面围岩控制难度较大的问题,采用顶板切顶卸压开采技术,以3号煤层所属工作面为研究对象,在对其顶底板条件分析及其沿空留巷原支护方案分析的基础上,提出了切顶卸压开采的工艺参数,并对其围岩提出强化支护方案。最后通过对支护方案的实施效果进行监测,取得理想结果。In order to solve the problem of the difficulty of controlling the peripheral rock of the working face by the mining technology of leaving the roadway in the air,we adopt the technology of cutting the roof and unloading the pressure on the top plate,taking the working face belonging to the No.3 coal seam as the object of the research,and based on the analysis of the conditions of the top and bottom plates and the analysis of the original support scheme of the roadway in the air,we put forward the technological parameter of cutting the top and unloading the pressure on the top plate and propose the reinforced support scheme for the peripheral rock,and put forward the reinforced support scheme in the roadway;Finally,by monitoring the implementation effect of the support programme,and achieve ideal results.
