Abstract

In order to solve the serious problem of roadway deformation and failure in the advance section of large mining face under deep high stress conditions, taking the mining roadway of 2112 working face as the research background, the stress distribution law of surrounding rock in the mining roadway of high stress and large mining face is analyzed by numerical simulation, and different sections in advance are divided. The control scheme of roadway surrounding rock is put forward and applied in the field. The results show that the deformation of roadway surrounding rock is controllable and the supporting effect of surrounding rock is good after adopting the new supporting scheme, which provides a case reference for the control of surrounding rock of the same type of roadway.
