卫辉市米山洞灰岩矿历史遗留采场矿山地质环境问题分析及防治

Analysis and prevention of geological environment problems of Mishandong limestone mine in Weihui City

卫辉市米山洞灰岩矿为资源整合矿山,经过以往长期开采,现已形成了大规模的历史遗留露天采场,导致了一系列地质环境问题。通过对米山洞灰岩矿历史遗留露天采场开展矿山地质环境调查发现,主要地质环境问题为崩塌、地形地貌景观破坏、土地损毁等,含水层破坏影响较轻。充分考虑矿山地质环境现状特征及防治措施,将历史遗留露天采场划分为重点治理区。针对不同的矿山地质环境问题,采用危岩体清除、防护及警示工程、场地平整、废渣回填及覆土、土壤改良、植被恢复及修筑排水沟等工程措施,消除地质灾害隐患,修复地形地貌及土地资源,不仅提高了土地资源利用率,而且改善了人居生态环境。

Mishandong limestone mine in Weihui City is a resource integration mine.After long-term mining in the past,a large-scale historical open-pit has been formed,resulting in a series of geological and environmental problems.Through the investigation of the geological environment of the mine in the historical open pit of mishandong limestone mine,it is found that the main geological environment problems are collapse,destruction of landform and landscape,land damage,etc.,and the impact of aquifer damage is relatively small.In full consideration of the current geological environment characteristics of the mine and the prevention and control measures,the historical open pit is divided into key treatment areas.Aiming at different mine geological environment problems,engineering measures such as dangerous rock body removal,protection and warning works,site leveling,waste residue backfilling and soil covering,soil improvement,vegetation restoration and drainage ditch construction are adopted to eliminate geological hazards,restore topography and land resources,not only improve the utilization rate of land resources,but also improve the ecological environment of human settlements.
