Abstract: In order to improve the stability of high pumping roadway, the abutment pressure distribution of S1302 high pumping roadway during excavation is analyzed by numerical simulation. the method of subsection driving was used for a total of 3 times. The results show that the distribution characteristics of lateral abutment pressure on the left and right sides of high drainage roadway are different during excavation. On the side near the solid coal, the lateral abutment pressure decreases gradually with the increase of distance. On the side near the return air drift, the lateral abutment pressure decreases rapidly with the increase of distance. When the influence range of S1302 return air drift is exceeded, the lateral abutment pressure gradually increases to the original rock stress and then remains unchanged.
