摘要
根据矿山的实际情况,通过FLAC^(3D)软件建立矿山采空区模型,以分析原始采空区上覆岩层受力以及位移。在最危险位置施加等效于矿用卡车重量的垂直载荷,而且不断增加载荷的大小,使其达到上覆岩层所能承载的极限载荷,从而确定出矿山能够通过的最大矿用卡车。
According to the actual situation of the mine, the model of mined out area of mine is established by FLAC3D software,by analyzing the force and displacement of the upper strata in the original mined out area. In the most dangerous position, the vertical load is applied to the weight of the mine truck, and the size of the load is increasing, so that the ultimate load of the bearing stratum can be reached. So as to determine the position can be changed through the largest mining trucks.
