摘　　要：随着煤矿开采深度的增加,煤矿生产对工作面布置、回采方式及支护强度的要求也越加严格。以大阳煤矿3307运输顺槽工作面为研究对象,采取数值模拟分析方式研究巷道围岩支承应力分布规律与异形煤柱变形破坏特征。基于此,对新掘巷道围岩进行加固施工,以解决新掘双煤巷的加固支护问题。针对性的高强护表锚杆(索)支护,保证了围岩的稳定性,取得了良好的支护效果,可以为同类型矿井工程提供借鉴。With the increase of coal mining depth,the requirements of coal mining on the layout of working face,mining methods and support strength were becoming stricter.Taking 3307 transportation channeling face of Dayang Coal Mine as the research object,the distribution law of supporting stress in surrounding rock and deformation and failure characteristics of irregular coal pillar in the roadway were studied by numerical simulation.Based on this,the surrounding rock of the new excavation roadway was reinforced to solve the reinforcement and support problem of the new excavation double coal roadways.The stability of surrounding rock was ensured by the targeted high-strength rock bolt(cable)support,and good support effect was obtained,which can provide reference for the same type of mine engineering.
