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。
Taking the geological conditions of a mine face 4102 as a background, the finite difference software FLAC3D was used to simulate the driving and mining of the roadway driving along gob and the deformation degree of the roadway was effectively reduced after the joint support of bolt and shotcrete was adopted.
