Abstract: In order to solve the mine strata pressure bumping accident frequently occurred in Huafeng Mine, the theoretical analysis, numerical simulation and site observation method were applied to study on the mine strata pressure released measures of the coal mining face .Based on the pressure released advance mining in N 0.6 seam under the floor of No.4 seam, according to the combined pressure released principle of the coal mining in the upper liberated seam and the low liberated sea m, a design study was conducted on the layout method of the coal mining face in No.1 seam above the roof of No.4 seam.The pressure released parameters of the shor twall mining face were obtained with the theoretical analysis and the numerical simulation and the industrial trial and the trial results verification were conducted.The re sults showed that after the pressure released, the deformation value of the mining gateway in the coal mining face was obviously reduced and the shortwall mining in th e up liberated seam could effectively reduce the danger of the mine pressure bumping occurred in the air retuning gateway of the coal mining face in No.4 seam.
