【摘要】：云南省是矿业大省,蕴藏着丰富的矿产资源,为云南省的国民经济发展做出了巨大的贡献。但是在开发利用矿产资源促进经济发展的同时,也诱发了一系列地质环境问题。这些地质环境问题不仅给矿区的地质环境造成严重危害,也间接导致当地人民生产生活受到严重威胁。因此,对矿山地质环境质量进行评价以及合理开发矿产资源成为保护矿山地质环境的当务之急。论文以云南省宾川县继磊页岩矿为研究对象,通过收集项目区相关资料,分析矿山的地质环境现状。然后结合项目的开发利用方案,对项目区矿山地质环境进行综合评价和环境影响预测,并根据评价结果提出相应的生态治理恢复措施。通过对矿山地质环境进行综合评价,得出以下结论：(1)宾川县继磊页岩矿山地质环境条件复杂程度为中等,矿山地质环境影响评估级别为二级,地质灾害危险性级别为三级。矿山地质环境影响程度现状评估分级为较轻区。矿山地质环境影响程度预测评估划分为较严重区和一般区二个。(2)针对宾川县继磊页岩矿山存在矿石及废渣易引发崩塌、泥石流等地质灾害,压占土地,破坏生态环境等地质环境问题,矿山闭坑后,工程部署以降低地质灾害发育程度,恢复生态环境的生态治理恢复措施。具体保护与治理工程为截排水措施、浆砌石挡墙及恢复生态工程。(3)通过效益分析,本工程具有较好的社会效益、经济效益和环境效益。
[Abstract]:Yunnan Province is a big mining province with rich mineral resources, which has made a great contribution to the development of the national economy of Yunnan Province. However, the exploitation and utilization of mineral resources to promote economic development at the same time. These geological environmental problems not only cause serious harm to the geological environment of the mining area, but also indirectly lead to the serious threat to the production and life of the local people. It is urgent to evaluate the quality of mine geological environment and to develop mineral resources reasonably. This paper takes Jilei Shale Mine of Binchuan County Yunnan Province as the research object. Through collecting the relevant information of the project area and analyzing the present situation of the geological environment of the mine, combined with the development and utilization of the project, the comprehensive evaluation and environmental impact prediction of the geological environment of the mine in the project area are carried out. According to the evaluation results, the corresponding measures of ecological restoration are put forward. Through the comprehensive evaluation of the geological environment of the mine, the following conclusions are drawn: 1) the geological environment conditions of the Jilei Shale mine in Binchuan County are of moderate complexity. The grade of mine geological environmental impact assessment is two. The grade of geological hazard risk is three levels. The assessment of the present situation of mine geological environment impact is classified as light area. The prediction and evaluation of mine geological environment influence degree is divided into two areas, I. e., more serious area and general area. In view of the existence of ore and waste slag in Jilei Shale Mine, Binchuan County, it is easy to cause collapse. Geological hazards, such as debris flow, occupy the land, destroy the ecological environment and other geological environmental problems. After the mine closes the pit, the project is deployed to reduce the degree of geological hazard development. The concrete protection and treatment project is the interception and drainage measure, the slurry stone retaining wall and the restoration ecological project. Through the benefit analysis, this project has the better social benefit. Economic and environmental benefits.
