在岩溶矿区由于疏干排水的原因,引起地面不同程度的塌陷现象,国内外有关的科研工作者,多数都认为是地下水潜蚀的结果,从而提出用回填法进行治理。但实践证明,回填法并不能治服塌陷的重演,有的地区回填后又继续不断地发生塌陷。例如苏联的北乌拉尔铝土矿用混凝土回填河床塌陷,过后又多次发生塌陷。可见塌陷的形成实质很值得进一步研究和探讨。我们通过野外观察、资料分析和室内模拟实验结果认为,塌陷主要是由于赋存 In the karst mining area, due to drainage and drainage, causing different degrees of collapse on the ground, the majority of researchers at home and abroad think it is the result of underground water erosion and propose to use the backfill method for treatment. However, practice has proved that the backfill method can not cope with the recurrence of collapse, and some areas continue to collapse after backfilling. For example, the Northern Ural bauxite in the Soviet Union collapses with a concrete backfill riverbed and collapses many times thereafter. Visible collapse of the formation is indeed worth further study and discussion. Through field observations, data analysis and laboratory simulation results, we believe that the collapse is mainly due to occurrence
