The high ground stress surrounding rock control is difficulty of deep mine support, FLAC3D software was applied for the study of deep mine semicircle roadway surrounding rock weakening law under high ground stress, is found that the deep mine high ground stress surrounding rock appears discontinuous distribution of plastic zone, with time, the plastic zone increases, that deep mine surrounding rock belongs to nonlinear mechanical system. Meanwhile, the surrounding rock stress and displacement that under different side pressure coefficients were simulated, and got the change of the situation in the roadway on both horizontal and vertical direction, and the different ground stress impact on deep shotcrete rockbolt mesh plus cable support were analyzed. The technology was put forward for high strength, high stiffness and a wide range for deep mine with high stress surrounding rock control, and the supporting effect was monitored under different ground stress situations, and good support effect was obtained.
