Abstract: The surrounding rock of Gangli Mine is weak and broken,and the ground pressure appears more and more intense with the mining depth extending,which seriously affects the normal mining of Gangli Mine.In this paper,through the study of softbroken wall rock mining in Gangli Mine,the factors and mechanism affecting the normal mining are analyzed, and the mining order is adjusted,so that the difficulty of softbroken Wall rock mining in Gangli Mine is fundamentally reversed,the key problem of ground pressure management is to select the stable surrounding rock,to arrange the slope and the joint roadway in the fully relieved pressure position,and to select the high stress area where the surrounding rock is broken.

Key words: Ground pressure appearance,Soft broken surrounding rock,Mining sequence,High Stress Area
