Abstract: For the roadway driven along next gob and heading adjacent advancing coal face in close distance coal seams, the excavation process is subject to the multi-perturbation of the coal pillar left by the upper coal seam, the leading support pressure of the upper section working face, the hysteresis support pressure and the lateral support pressure of the goaf. The resulting maintenance problems are analyzed by theoretical analysis and numerical calculation methods, and corresponding support schemes are developed. Through the underground industrial test and the whole process of mine pressure monitoring, the rationality of support scheme is verified, the specific range of disturbances at each stage and the plastic damage range of coal pillars are determined. Thereby providing a basis for the next working face roadway layout.
