Abstract
In view of the problem of long service period and support strength reduction of the underburden concentrated belt downhill main roadway in the 13upper18 working face of Daizhuang Coal Industry,the surrounding rock characteristics and deformation mechanism under the original support scheme are studied through a combination method of on-site measurement and numerical simulation.The control and migration characteristics of anchor rods(cables)on the roadway surrounding rock under different support parameters are analyzed,and the existing shortcomings of the original support scheme are found.The research results show that the strength of the shallow surrounding rock of the concentrated belt downhill is relatively low,and plastic damage is severe.There is a severe stress reduction area occures in the deep surrounding rock,with separation layer and cracks.Based on the original support scheme,the concentrated belt downhill can reduce the damage degree of the shallow surrounding rock of the roadway,improve the internal stress state of the surrounding rock,and increase the service life of the roadway through the method of reducing the length and row spacing of the anchor cables,optimizing the support plate components,and combining them with arched support plates and spherical washers.关键词
