Abstract
In order to investigate the supporting effect of the higher side of the trapezoidal roadway, setting three measuring points at a distance of 320m, 350m, 380m from the access adit to observe the surrounding rock deformation caused by the distance change between the measuring point and working face. The observation results show that the deformation of surrounding rock is still larger than the lower side, but the support scheme can effectively control the deformation of roadway surrounding rock, reduce the deformation and deformation rate of surrounding rock, and has economic advantages.关键词
