Analysis on Features of Ground Subsidence Caused by Underground Mining in Mountains

山区地下煤层开采引起的地面沉陷受多种因素的影响和制约。本文在贵州某煤矿二采区地质灾害调查的基础上,分析山区煤矿开采引起的地面沉陷特征及影响因素,得出山区矿山开采引起地面沉陷的一般规律。

There are many factors influencing and controlling the ground subsidence caused by underground min- ing in mountains. In this paper, the features and influencing factors of ground subsidence were analyzed on the basis of geological disaster investigation of No. 2 mining area of a coal mine in Guizhou, and the general laws of ground subsidence caused by mining in mountains were obtained.
