广西凤凰山灰岩矿矿山地质环境影响评估及主要治理恢复措施

Geological Environment Impact Assessment and Governance Restoration Countermeasures of Fenghuangshan Limestone Mine in Guangxi Province

在了解矿山基本概况和查清矿山地质环境条件的基础上,结合矿山实际情况,从地质灾害、含水层、地形地貌景观和土地资源等方面进行了矿山地质环境影响现状和预测评估。现状评估表明,该矿山主要发育滑坡和危岩,地质灾害中等发育,对土地资源和地貌景观影响较严重;预测评估表明,该矿山引发和遭受的地质灾害主要为崩塌和滑坡,对地下水影响较轻,土地资源和地貌景观影响严重。根据评估结果,提出了植被恢复工程、挡护工程、排水工程等矿山地质环境治理恢复措施,对消除或减弱矿山地质灾害,全面恢复矿山生态环境具有一定指导意义。

On the basis of knowing present condition and identifing mine geological environment of mine, combining with actual situation of the mine, from the aspects of geological disasters, aquifer, topography, landscape and land resources, present condition and forecast evaluation of geological environment affect to the mine have been carried out. As showed by present condition of the mine, it is regarded that the mine has mainly developed landslides and perrilous rocks. Geological disasters are in the moderate development, which will affect land and landscape seriously. As showed by forecast assessment, it is indicated that col- lapse and landslides are main geological disaters caused by the mine. It has lighter impact to groundwater, while has serious impact to land resources and landscape. Based on the assessment results, some countermeasures have been put foward to restoring geological environmen, such as vegetation restoration, block retaining works and drainage works. It will provide some references for eliminating or weakening geological disasters in the mine.
