Abstract: In order to solve the problem that the existing coal pillar layout method of Shaqu No.2 mine seriously restricts the safe and efficient recovery of the mine, the 4^# and 5^# coal of Shaqu No.2 mine was used as the research object, and the reasonable width of coal pillar was obtained by theoretical analysis and calculation; UDEC numerical simulation was used to determine the layout of 5302 trackway by simulating the roadway associated with different superimposed coal pillar structures in very close coal seams; engineering tests were conducted to The engineering test was used to observe the mine pressure in different test sections. The research results show that: ① The reasonable coal column width of the front section of 5302 trackway is 61.4m, and the reasonable coal column width of the rear section of 5302 trackway is 12.8m; ② The front section of 5302 trackway adopts the small staggered distance internal staggered arrangement, and the internal staggered 4302 trackway is 5m, and the rear section of 5302 trackway is arranged at the position of 12m from the filling body next to the roadway; ③5302 working face back mining roadway top and bottom plate shift up to 286mm, two helpers shift up to 95mm, roadway support pressure in the roadway dug out gradually stabilized, roadway surrounding rock plastic zone range is not large, roadway surrounding rock control effect is good.
