河南灵宝市灵金一矿矿山地质环境问题及恢复治理研究

Mine geological environment problems and restoration treatment of Lingjin No.1 Mine,Lingbao City,Henan Province

本文对位于河南灵宝市的灵金一矿矿山进行了研究,分析了矿山地质概况和主要地质环境问题,并提出了针对性的治理措施。结果表明:矿区内水文地质条件简单,大气降水是唯一的补给来源,地形有利于地表水的排水;矿渣堆在水托浮力作用下极易产生泥石流灾害,强烈的地表径流为泥石流的产生提供了强大动力条件;提出修建“排水渠+挡土墙”的治理措施,验算结果表明该方案在3种工况条件下均能够满足50年一遇的治理需求。

In this paper,the mine of Lingjin No.1 Mine located in Lingbao City,Henan Province was studied.The geologic aspects and the main geological environment problems were analyzed,and corresponding treatment measures were put forward.The results showed that the hydrogeological conditions in the mining area were simple.Atmosphere precipitation was the only supply source,and the terrain was conducive to drainage of surface water.The slag pile was easy to produce debris flow under the action of water buoyancy,and the strong surface runoff provided a strong dynamic condition for the generation of debris flow.The treatment measures of“drainage channel+retaining wall”were proposed.The checking results showed that the scheme can meet the once-in-50-year needs in all three working conditions.
