永定庄煤矿地质环境问题分析及治理研究

Analysis and Treatment of Geological Environmental Problems in Yongdingzhuang Coal Mine

矿山生态修复对矿山的安全和发展具有重要作用,永定庄煤矿存在的不稳定斜坡和建筑垃圾堆放引起的地貌景观破坏等地质环境问题已严重影响了矿山的发展和周边人员的生命安全。结合研究区内地形地貌特征和室内试验,采用传递系数法对研究区内的不稳定斜坡进行“天然”、“暴雨”和“地震”三种工况下的稳定性计算,根据稳定性分析结果对该边坡进行了加固处理。对区域内的建筑垃圾根据分布特点进行清运和平整复绿或就地压实、平整复绿。经过一系列治理该矿区的地质环境问题已得到解决,该矿山的修复治理措施可为其他矿山生态修复提供参考。

Ecological restoration of mines plays an important role in the safety and development of mines.The unstable slopes in Yongdingzhuang Coal Mine and the destruction of landforms and landscapes caused by piles of construction waste have seriously affected the development of the mine and the lives of surrounding personnel.Combining the topography and geomorphology characteristics of the study area and laboratory tests,the transfer coefficient method is used to analyze the stability of the unstable slopes in the study area under three working conditions:"natural","heavy rain"and"earthquake".According to the stability analysis result,the slope was reinforced.According to the distribution characteristics,the construction waste in the area shall be cleaned,transported and re-greened or compacted and re-greened on the spot.After a series of treatments on the geological environment of this mining area,the problems have been solved,and the restoration and treatment measures of this mine can provide a reference for ecological restoration of other mines.
