In order to study the mismatch problem of the strike of the working face in the cooperative mining of the upper and lower coal seams, taking the joint arrangement of the No.12 and No.13 coal seams of a coal mine as the engineering background, the theory of stable pressure zone is used to study the movement law of the overburden when the working face of the upper and lower coal seams is mined simultaneously, and the mechanical structure model of the overburden of the stope when the close coal seams are mined simultaneously is established. the wrong distance of mining in No.12 coal seam and No.13 coal seam at the same time is chosen reasonably and verified by field practice. the results show that the co-mining misdistance of No.12 coal seam and No.13 coal seam should be controlled in the range of 40 m～50 m, at this time, the mutual disturbance influence of the two coal seams is minimal. when the No.13 working face is arranged in the No.12 mined-out area, the overlying rock above the mined-out area is gradually stable. the influence of No.12 coal mining on the No.13 coal working face disturbance is small, and the change of mine pressure is not obvious. when the upper and lower coal seams are cooperatively mined, the working face support form of no.13 coal seam is large mining height support, and the fully mechanized mining adopts the all-height and all-caving mining technology in one mining. the misspacing scheme in the same mining direction of close coal seam is applied to the field practice, and the production condition of the upper and lower coal seam working face is good, which indicates that the selected safe misspacing can meet the safety production.
