Aiming at the problem of severe mine pressure in retaining roadway during simultaneous mining of close-distance coal seams, taking the 9102 and 10102 working faces of Jiaokou Coal Mine in Shanxi Province as the engineering background, the mechanical model of simultaneous mining of close-distance coal seams and the mechanical model of roof cutting and retaining roadway are established. Through theoretical analysis, numerical simulation, industrial test and other methods, the coupling weakening law of mining distance and roof cutting height on the stress of surrounding rock of retaining roadway is clarified. The reasonable mining staggered distance and roof cutting parameters are determined : the mining staggered distance is 30m, the roof cutting height is 6m ( the layer spacing is 10m ) and 11m ( the layer spacing is 15m ). The field test results show that when the interlayer spacing is 15 m, the roof deformation of the top cutting side of the 10102 transportation gateway is 71.61 mm, which is reduced by 38.2 %, and the hydraulic support pressure at the end of the working face is 25.47 MPa, which is reduced by 25.8 %, indicating that the optimization effect is good. The research results can provide theoretical basis and engineering reference for the roof cutting and roadway retaining technology under similar conditions.
