The strata movement and the ground surface subsidence caused by underground mining are serious underground engineering problems.
地下开采引起的岩层移动和地表沉陷是一个非常严重的地下工程问题。
With the difference of lithological characters considered, the generalized subsidence formula for strata and surface movement is derived. Some applied fields and an example are given.
在考虑岩性差异的条件下，推导出了岩层与地表移动的广义下沉公式，最后列举了其应用意义和实例。
The laws on the rock strata and surface movement that have known is basically based on the rock strength, not considering exist and the effect on the subsidence laws of the fissure and the weak face.
已有的岩层与地表移动规律基本上以岩石强度为基础，很少顾及岩体中裂隙弱面的存在，及其对岩层与地表移动规律的影响。
