【摘要】 准格尔矿区位于内蒙古自治区鄂尔多斯市,地处黄土高原边缘区,是全国重要煤炭生产基地之一。由于矿业开发与利用,给矿区的环境带来了多方面的、不同程度的破坏,一系列地质环境问题亟待解决。论文通过遥感技术及野外调查等手段,结合对研究区矿山地质环境现状数据统计,对矿区矿业活动引发的环境地质问题进行分析。确定了矿区水环境、土地资源占用、边坡失稳、水土流失、土壤侵蚀等方面的环境问题,对该类问题进行了评价,分析各类地质环境问题的诱发机制、影响因素及危害性。论文根据评价分析结果,结合较为成熟地区的环境治理办法,针对各种不同的地质环境问题,分析矿区环境问题的差异性,提出相应的治理对策,总结了适合该研究区域的矿山环境综合治理办法。通过研究论文得到如下结论:(1)矿区最主要环境地质问题为土地资源占用,其次为地表水污染、水土流失、边坡失稳。(2)根据评价结果将矿区分为环境影响严重区和较轻区,分别占比24.6%和75.4%。(3)矿区根据污染程度的不同,分为重点保护治理区和一般保护治理区,并有针对性合理布置防治工程。论文研究结果为今后在矿区推广环境地质动态管理系统奠定基础,为总体规划决策和矿区开采规划、环境保护治理重建等规划的制定和实施提供环境地质科学依据。该论文有图11幅,表25个,参考文献102篇。更多还原

【Abstract】 Zhun Geer Mine Area is located in Ordos City,Inner Mongolia Autonomous Region,located in the edge of the Loess Plateau,is one of the important coal production bases in China.Due to the exploitation and utilization of the mining industry,the environment of the mining area has been damaged in many ways and in different degrees,and a series of geological environment problems need to be solved urgently.In this paper,by means of remote sensing technology and field investigation,combined with the data statistics of the mining geological environment in the study area,the environmental geological problems caused by mining activities in the mining area are analyzed.Determine the mining area water environment,land resources occupation,slope instability,soil erosion,soil erosion and other environmental problems,such as the evaluation of these problems,analysis of all kinds of geological environment problems induced mechanism,influence factors and harm.Based on the results of evaluation and analysis,combined with the environmental control methods of relatively mature areas,the paper analyzes the differences of environmental problems in mining areas in view of various geological environment problems,puts forward the corresponding control countermeasures,and summarizes the comprehensive control methods of mine environment suitable for the study area.Through the research paper,the following conclusions are drawn :(1)the most important environmental geological problems in the mining area are the occupation of land resources,followed by surface water pollution,soil erosion,slope instability.(2)According to the evaluation results,the mining area is divided into serious area and light area,accounting for 24.6% and 75.4%,respectively.(3)According to the pollution degree,the mining area is divided into key protection and control area and general protection and control area,and the prevention and control projects are reasonably arranged accordingly.The research results of this paper lay a foundation for popularizing the dynamic management system of environmental geology in the mining area in the future,and provide a scientific basis for environmental geology for the overall planning decision-making,mining planning,environmental protection,governance and reconstruction and other planning.更多还原
