摘要
通过对某矿2302综采面的矩形回采巷道的围岩的变形量进行设点观测,并借助于FLAC3D软件模拟计算随工作面推进回采巷道超前支承压力,研究分析现场实测及FLAC3D软件的模拟结果,得出了2302综采面的巷道围岩变形规律,为工作面的顶板管理和回采工作提供了相应的科学依据。
By setting points in rectangular mining roadway of 2302 fully mechanized face, the surrounding rock deformation is observed, and the advanced abutment pressure is simulated by FLAC^3D, then the measured and simulation result is researched and analyzed, the deformation law of 2302 mechanized face roadway surrounding rock is derived, the corresponding scientific basis is provided to roof management and recovery.
