摘　　要：根据胜利煤矿3#煤层具体地质条件,通过岩石力学实验得出岩样的物理力学参数,在此基础上采用实验室相似模拟、数值模拟等方法,研究了胜利煤矿3#煤层综采面矿压显现规律,最终确定了综采面合理的液压支架工作阻力为13 000 kN,架间距1.75 m,顶梁长度4.7 m的支架,为胜利煤矿综采面液压支架的设计和安全高效生产提供了依据和保障。Abstract：This thesis gets physical and mechanical parameters through rock mechanics experiments according to the specific geological conditions of 3^# coal seam in S hengli Coal Mine. On this basis,we adopted laboratory simulation, numerical simulation, studied the mine pressure-visualized patterns at the fully mechanized face in 3^#coal seam, and finally regularized the rational hydraulic support working resistance 13 000kN, the spacebetween 1.75 m, the kickstand with the beam length 4.7 m, providing basis and relerences tor the hydraulic support design and high efficiency production at the fully mechanized coal face.
