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。
According to the specific geological conditions of seam # 3 in Shengli Coal Mine, the physical and mechanical parameters of the rock specimen are obtained through the rock mechanics experiment. Based on this, laboratory simulation and numerical simulation are used to study the pressure of the fully mechanized coal mining face of seam # 3 in Shengli Coal Mine The law of appearance shows that the reasonable working face of hydraulic powered support is 13 000 kN, the distance between frames is 1.75 m, and the length of top beam is 4.7 m. It provides the basis for the design, safe and efficient production of hydraulic support in Shengli Coal Mine And security.
