井下开采引发地面塌陷预测方法研究

The Prediction Method Research for Ground Subsidence Induced by Underground Mining

由煤矿井下开采引发的采空区地面塌陷,是普遍存在的工程地质和地质环境问题。开采塌陷是矿山环境地质灾害的直接根源。本文根据陕西省延安市A煤矿的资料,运用概率积分法,对煤矿开采可能引发地面塌陷的范围进行预测。结果表明,该方法可计算得出地面塌陷的位置及面积,为矿山的环境保护和土地复垦提供科学依据。

The ground subsidence induced by the coal mine underground mining is a prevalent problem in the engineering geological and environmental geological. Mining subsidence is the direct cause of mine environmental geological disasters. In this paper, according to A coal mine information of Yanan city of Shaanxi province, the Author forecasted the ground subsidence range prediction of the coal mining using the probability integral method.
