煤矿开采对高速公路影响的评价

从煤矿井田中部穿过的高速公路在建设和运营过程中,必须及时掌握煤矿地下开采对其采动影响情况.根据煤矿地质采矿条件,对煤矿地下开采在高速公路沿线所引起的地表移动和变形进行预计,给出高速公路沿线地表移动变形值.由预计结果评价了煤矿开采对高速公路的损害程度.结果表明,煤矿开采后引起的地表变形值超过了高速公路的允许变形值,它对高速公路的采动损害程度明显.

Analysis of the effects of underground coal mining on expressway

When expressway passes through a coal mine, it is necessary to know the effects of the underground coal mining on expressway. Based on the geologic and mining conditions, the surface movement and deformation along expressway were predicted, values of surface movement and deformation were obtained, and then the mining damages of the expressway due to coal mining were analyzed and evaluated. The results demonstrate that the values of surface movement and deformation are bigger than the critical values of the expressway. The mining damages due to coal mining under expressway are visible and serious.
