付村煤矿3_下1001材料巷破碎段支护方式优化研究

Optimization research on supporting method of broken section in 3_(lower) 1001 material lane in Fucun Coal Mine

以付村煤矿3_下1001材料巷为研究对象,对该段巷道矿压规律、顶板及巷道帮部围岩结构进行观测,并结合巷道所处的工程地质条件,初步确定该段巷道顶板完整程度受到3_上煤层的开采损伤影响。研究分析了影响3_下1001材料巷稳定的影响因素,提出了3_下1001材料巷的修复支护方案,现场施工取得较好效果,巷道围岩变形得到了有效控制。

Taking the 3（lower）1001 material lane of Fucun Coal Mine as the research object,through observation of the roadway roof structure,and combining the engineering geological conditions of the roadway,the completeness of roadway roof is initially determined,which shows it is affected by the mining damage of the 3（upper）seam.The factors influencing the stability of the roadway are analyzed in detail.The repair and support method of the 3（lower）1001 material roadways is proposed.On-site construction achieves favorable results and the deformation of surrounding rocks is effectively controlled.
