布沼坝露天矿新邓耳排土场泉眼出水处理措施

Spring yielding water treatment measures at Xindenger dump in Buzhaoba open-pit mine

新邓耳排土场为小龙潭矿务局布沼坝露天矿五期扩建后新增的外排土场,自2009年开工建设以来使用状况良好,目前遇到的主要问题是雨季S3泉眼点涌水量突增,泉水突出地表造成大面积积水,严重威胁到排土场整体稳定。为了能排除这一安全隐患,结合新邓耳排土场的水文地质条件,泉点分布及测流成果,进行泉水来源及处理分析,经多方面的技术经济比选,最终提出针对新邓耳S3泉眼点出水状况的处理措施。

Xindenger dump is an additional external dump after Buzhaoba open-pit mine extending. The dump has been in good condition since 2009, at present, and its main problems are $3 spring water inflow increasing in rainy season. Spring overflow caused a large area of stagnant water and seriously threatened the whole stability of dump. In order to exclude the potential safety hazard, the article analyzes spring source and treatment combining hydrogeological conditions, spring distribution and test flow results. Through many aspects technical and economic selection, the article finally presents treatment measures aiming at $3 spring yielding water condition in Xindenger.
