中文摘要：

由矿层井下采矿工程引发的采空区地面塌陷,是矿层开采普遍存在的环境工程地质问题。开采塌陷是矿区环境地质灾害的直接根源。本文根据矿山的数据资料,运用三角函数数学方法,对矿山开采可能引起的地面塌陷范围进行预测。结果表明,该方法可得出地面塌陷的位置及面积,为矿山的土地复垦及有效管理提供了科学依据,有助于实现“谁受益,谁治理”的目标。

英文摘要：

The empty area ground＇s subsidence which be caused by exploration engineering on mineral layer is the widespread environmental engineering geologic problem . Subsidence is the direct source of geological disaster; this text makes use of the data of mine and mathematic method of trigonometric function to forecast the possible scope of ground subsiding area. The results indicate that this method can get the position and area of subsiding area and it provides scientific according for the reclamation and sufficient management of mine, and it is useful to realize the goal ＂who be subjected to benefits, who manages＂.
