Optimization Design and Research of Roadway Support Scheme for No.2605 Working Face in Lu'an Mine
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.
