煤炭开采引起的地表土地沉陷,不仅使部分农田被毀,生态失衡,而且对地面的建筑物、道路、铁路、桥梁和输电线造成不同程度的破坏,易诱发山体滑坡、崩塌和泥石流等自然灾害,严重破坏矿区的土地资源和生态环境。因此,对采煤沉陷区采取防治,使其恢复到可利用的状态刻不容缓。 The subsidence of surface land caused by coal mining not only destroyed part of the farmland and caused ecological imbalances, but also destroyed buildings, roads, railways, bridges and transmission lines to varying degrees and caused natural disasters such as landslides, collapses and debris flows. , Seriously destroying the land resources and ecological environment in the mining area. Therefore, the coal mining subsidence zone to take prevention and control, make it back to the available state without delay.
