摘要
为了张家峁煤矿5-2煤工作面安全回采和常家沟水库水资源保护,根据水文地质调查结果,采用水位流量响应法确定了水库水是陈家塔沟泉水的来源;按照水库、烧变岩、泉点的地质关系分析了水库补给泉水的通道,认为4-2煤烧变岩与水库存在水力联系,为开采煤层上覆烧变岩帷幕截流工程提供了重要的依据。烧变岩帷幕截流工程及相应水文地质工作证明了研究成果。
For safe extraction of the coal No.5 -2 working face and the Changjiagou reservoir water resources protection,on the basis of hydrogeological exploration results,through corresponding water level (flow) method has assigned the reservoir water is the source of the springs in Chenjiatagou.According to the geological relationships among reservoir,burnt rock and spring point have analyzed the recharging channel between reservoir and spring point,considered that hydraulic connection is existed between coal No.4 -2 burnt rocks and reservoir,thus provided significant basis for curtain water closure engineering of coal overlying burnt rocks.The succeeding burnt rock curtain water closure engineering and corresponding hydrogeological works have affirmed the studied results.
