徐州潘安湖二期工程地质稳定性研究

The Geological Stability Research of the Second Engineering in Xuzhou Pan’an Lake

摘要: 随着国民经济和城市建设的快速发展，城市建设用地日益紧张，把煤矿采空区作为建设用地已经成为缓解用地紧张的一种有效手段。本文通过分析徐州矿物集团旗山煤矿和权台煤矿的采空区分布特征，开采时间、开采面积及其已引发的地面变形破坏情况，运用概率积分法预测采空区地面塌陷的残余变形量，将评价区分为不稳定、相对稳定和稳定三个区，并对采空地面塌陷提出防治措施及建议，以期对工程建设提供地质依据。

Abstract: As the rapid development of national economy and urban construction, the land of urban construction is scarce increasingly. So the coal mine goaf as construction land has become a kind of effective way to relieve the strain on land. In this article, through analyzing the distribution characteristics, mining time, mining area and the ground deformation damage in Qishan coal mine goaf and Quantai coal mine goaf of the Xuzhou mineral group, predicting residual deformation of surface collapse of the goaf with the probability integral method. The evaluation is divided into not stable, relatively stable and stable, and puts forward prevention measures and suggestions to the goaf ground so that the geological basis is provided for engineering construction.
