Abstract The deformation of deep large section high stress crushing soft rock roadway is a serious obstacle to safe and efficient mining in China's deep mines. By analyzing the deformation law of the surrounding rock in the lower mountain of the 22 mining area of Quandian Mine, optimizing the anchor cable support parameters, analyzing the influence characteristics of the surrounding rock shift and maximum principal stress by using FLAC3D numerical calculation, finding the best length of anchor cable was 8 m, and proposing the anchor cable length matching scheme for economic factors, verifying the reasonableness of the scheme by field measurement, and serving as a reference for similar mines.
