Abstract
In order to reveal the rock pressure behavior of high water filling along goaf retaining roadway in fully mechanized mining face with large burial depth,No.182605 lower working face of Wutongzhuang Mine was taken as the engineering background.theoretical analysis,scheme design and on-site monitoring were used to carry out research.According to the observation and analysis of the surrounding rock deformation and rate change law of the field roadway,it was known that the accumulative deformation and deformation rate increased slowly and then increased significantly,and then remained stable,after a set of technologies of"advance roof cutting.pressure relief and high water filling combined support".The deformation rate was in the shape of Chinese word"几".The surrounding rock deformation of the roadway was divided into three areas,namely the slow deformation area,the significant deformation area and the stable deformation area.The working face cycle pressure step distance was 35～40 m,which plaied an effective role in the control of the roadway surrounding rock.关键词
