Abstract: The concentrated main roadway in Wangjialing mining area is prone to occur deformation and instability caused by the stoping influence of the two wing fully mechanized caving face, which seriously affects the safe and orderly production of the mine. Therefore, it is proposed to adopt pressure relief roadway method for governance. Adopting theoretical analysis calculation, numerical simulation and other means, analysis is carried out around the reasonable layout location and support scheme of the pressure relief roadway. Through theoretical calculation, the minimum safe dimensions of the load-bearing coal pillar and yielding coal pillar are determined to be 9 m and 10 m, respectively. The reasonable layout location of the pressure relief roadway should be determined at a distance of 25 m from the stop mining line based on the simulation results analysis. The specific layout location of the pressure relief roadway is determined combined with the actual situation of the 22104 working face, and an anchor net cable joint support scheme is designed and adopted. The on-site engineering application shows that after the implementation of the pressure relief roadway in the 22104 working face, the maximum roof subsidence amount of the north auxiliary transportation main roadway is 68 mm (77% decrease compared to 300 mm without pressure relief), and the displacement amount of the two sides is 157 mm (72% decrease compared to 500 mm without pressure relief), the pressure relief effect is significant.
