摘要
通过剖析因地下采动造成阜新矿区自然村民井断水现象,对地下开采条件下水资源流失与恶化机理进行了分析研究。结果表明,即使采空区和受影响区处于不同的水文地质单元,因采动对隔水构造的破坏而形成地下水径流通道-空巷和裂隙,从而为水的流失创造了水文地质条件;地下水经过长时间聚集和物化作用发生水质恶化,失去使用价值。废弃关闭矿井水的资源化与利用问题,对水资源缺乏和煤炭资源枯竭、经济转型矿区具有现实的经济与社会意义。应该研究因抽取矿井水而引起的相关环境影响与灾害问题,防止出现二次破坏。
Through analyzing of waterbreak phenomeana in some residential wells in Fuxin mining areas, the article studied the mechanism of water resource running off and deterioration and concluded that although the goaf area and influenced area was in different hydrogeologic element, the groundwater runoff avenuecracks and hollow spaces those were resulted by mining to membrane brarrier structure damage become one of the convenient hydrogeological condition for water runoff; The deterioration of groundwater quality and the lost of use value that was resulted by aggregation effect, physics and chemical effect becomes one of the factors of soil degradation.The abandon and shutin coal mine water resource recovery and utilization have made economical and social effect to coal mining area where water resource is deficient, coal resources is depleted and economical type is transforming. It is necessary to research on environmental and disastrous problems resulted by draining mine water in order to prevent induced deepper and double damage.
