Abstract: The appearance of the stope underground pressure can damage surrounding rocks and supports of the mine roadway,which influences the normal mining operation and production safety. Taking 2106 working face of Yonghua No.1 Mine as a engineering case,the theoretical calculation value of the pressure step distance of the mining pressure through comparing the theoretical calculation value of the pressure step distance of the mining pressure with field observation data,which can guide safety production of the stope face,and indirectly bring great economic benefits for coal mine.
