| Abstract: | By analysis of the stability of roof surrounding rock in track roadway at 29106 working face under close-distance mining condition in Xiqu Colliery,the author proposes the combined bolt-mesh-cable support,which has been proved to keep the roadway surrounding rock relatively stable and meet the requirements of safety mining of working face by tracking the support effect daily through two monitoring stations. |
