摘要
以某矿4102工作面的地质条件为背景,利用有限差分软件FLAC3D模拟沿空掘巷的掘进与回采阶段,在采用锚索与喷浆联合支护后,巷道变形程度得到有效降低。
Based on the geological conditions of 4102 working face of a mine as the background, the finite difference software FLAC^3D was applied to simulate the driving stage and mining stage of driving roadway along goaf, deformation of the roadway has been effectively reduced when used the combined support pattern of bolt-cable and shotcrete.
