| 摘 要： | 根据淮南矿区大量的资料分析,作者认为该地区岩溶地表塌陷的形成,必须具备三个基本条件:①地下水活动的通道;②一定厚度的覆盖层;③地下水的活动。具备上述条件的地段,在触发因素的作用下,即产生地表塌陷,但蹋陷的规模、数量、速度等,受一系列因素的制约。对于这些问题,在文中均做了详细的讨论。

| Abstract: | Conclusions are drawn after analyzing large quantities of data available concerning Huainan mining area that karstic surface collapses in this area will not occur without the presence of (1) a groundwater activity passage, (2) covering strata of a certain thickness and (3) groundwater activities, as well as of some off-triggering factor. Detailed discussions are made about karstic surface collapses as to their size, amout, velocity, etc. and to the responsible factors |
