摘要
Abstract
In order to achieve self formed roadway mining without coal pillars,using the 8106 fully mechanized mining face of WaJinwan Mine as the experimental face,numerical simulation and surrounding rock displacement monitoring were used,and technical measures such as roof cutting pressure relief,roadway reinforcement,and goaf sealing were adopted.The main parameters were studied,and the reasonable depth of the cutting seam was determined to be 7 m and the angle was 15°.Constant resistance and large deformation anchor cables were used for reinforcement and support.Mine pressure monitoring shows that the deformation of the surrounding rock in the retained roadway is small,and the support effect is good.关键词
