摘　　要：为了确保矿井复合顶板巷道在煤矿开采时的稳定,以潘三矿1692(1)工作面轨道顺槽为研究对象。针对原围岩的赋存状况和原有的支护方案进行分析,原支护方案暂时可以满足安全支护需要,但考虑本巷道为典型深部多次应力扰动下复合顶板沿空掘巷,采用数值模拟分析了锚杆与短锚索预应力承载结构。研究发现短锚索预应力承载结构的应力场范围更大,能够有效控制围岩变形。In order to ensure the stability of mine composite roof roadway in coal mining,the track crossheading of 1692(1)working face in Pansan Mine is taken as the research object.Based on the analysis of the occurrence of the original surrounding rock and the original support scheme,the original support scheme can temporarily meet the needs of safety support.However,considering that the roadway is a typical composite roof gob-side entry driving under multiple stress disturbances in the deep,the prestressed bearing structure of anchor rod and short anchor cable is analyzed by numerical simulation.It is found that the stress field range of short anchor cable prestressed bearing structure is larger,which can effectively control the deformation of surrounding rock.
