煤矿开采地面沉陷变形预测及防治对策

Prediction and countermeasures of prevention and controlof ground subsidence deformation in coal mining

随着煤矿的大面积开采,引发了较多的环境地质问题,其中采煤沉陷是矿区最常见的环境地质问题之一。本文以羊场湾煤矿为例,通过对矿区采空区地表沉陷状况进行调查,对沉陷区范围、影响程度进行现状评估,结合采掘接续计划,对中远期煤矿开采引起的地面沉陷变形进行分析和预测,提出防治对策,对指导矿山地质灾害预防、矿山生态环境恢复、绿色矿山的创建具有一定的指导意义。

With the large-scale mining of coal mines,more environmental geological problems were caused,among which coal mining subsidence was one of the most common environmental geological problems in mining areas.In this paper,taking Yangchangwan Mine as an example,through the investigation of ground subsidence situation in the goaf of the mining area,the scope of the subsidence area and the influence degree were evaluated.Combined with the mining continuation plan,the ground subsidence deformation caused by medium and long-term coal mining was analyzed and predicted,and the prevention and control countermeasures were put forward.The study had certain guiding significance for guiding the prevention of mine geological disasters,the restoration of mine ecological environment and the creation of green mines.
