江西武宁县东坪矿区地质环境问题及防治对策

Geo-environmental Problems and Control Countermeasures of Dongping Mining District in Wuning,Jiangxi Province

通过对武宁东坪矿区地质环境背景和现状调查,分析矿区可能产生的地质环境问题,发现主要矿山地质环境问题为:滑坡型泥石流,地裂缝、地面塌陷以及地下水均衡系统破坏以及对土地的侵占和破坏。提出主要防治对策有:修筑拦挡坝和截水沟等防治滑坡型泥石流;加强采场和采空区地压控制和管理,防治地裂缝、地面塌陷以及地下水均衡系统破坏;利用土地复垦的手段恢复被破土地的原始功能。

By investigating the geo-environmental background and current situation of Dongping mining district in Wuning,Jiangxi province, the potential problems are analyzed, and the major geo-environmental problems such as landslide type debris flow, ground crack, ground collapse, the destruction of the water balance system, the occupation and destruction of the land are discovered. Three major controlling countermeasures are proposed. First, the dykes and intercepting ditches are built to control the landslide-type debris flow. Then, the management and control of lithostatic pressure of the stope and the gob area are strengthened to prevent and control the occurrence of the ground crack, ground collapse and the destruction of the water balance system. Finally, the initial functions of the destroyed land are recovered through land reclamation.
