运用数值模拟软件FLAC3D建立几何模型,对极近距离煤层的采场矿压显现规律进行模拟研究。为矿区相类似的超前支护范围的确定及回采巷道补强支护参数的选取具有一定的指导意义。
The numerical simulation software FLAC3D is used to establish the geometric model to simulate the occurrence of underground pressure in stope of coal seam with very close distance. It is instructive for the mining area to determine the similar advanced support range and the selection of reinforcement support parameters for mining gateway.
