摘要
现场调研、数值模拟、理论分析相结合的方法,结合现场工程实践,对潞安漳村2605工作面巷道稳定性进行研究.选取2605工作面运巷、中风巷和进风巷为研究对象,根据相关地质资料,设计支护方案;对区域巷道变形破坏进行数值模拟分析,包括顶板下沉量、巷道两帮收敛及锚杆锚索工作载荷等.得到各支护方案的巷道变形破坏结果,并结合数值模拟结果确定2605工作面巷道的合理支护方案.
Abstract
The roadway stability of the No.2605 working face in Zhangcun Mine was studied using field investigation,numerical simulation,theoretical analysis,and on-site engineering prac-tice.Selecting the transportation roadway,mid-wind roadway,and air inlet roadway as research objects,we designed supporting plans based on relevant geological data to do the numerical simu-lation on the deformation and damage of the regional roadway,including the roof subsidence,the convergence of the two sides,and the working load of the anchor bolts and cables.Then,based on the deformation and damage results from the numerical simulation,a reasonable supporting plan for the No.2605 working face roadway was determined.
