【摘要】：随着我国矿业的快速发展,在带来大量的经济效益的同时,也伴生出了严重的环境问题。近几年,矿山环境问题日益突出,为了协调好经济与环境的可持续发展,需要对矿山地质环境做出科学的评价。攀西地区是我国重要的成矿带,该区矿产资源储量大、资源类型多样,由矿产资源取得了大量的社会经济效益,当地经济亦得到了突飞猛进的发展,而矿山开采带来的地质灾害和环境破坏也同时威胁着当地的人民的生存环境。文章结合收集到的矿山相关数据和矿山的实际情况对研究区域内矿山地质环境评价指标进行筛选与优化,分层次建立指标体系,通过层次分析法确定指标权重,利用模糊综合评价法建立矿山地质环境综合评价的数学模型,通过分形对研究区域进行综合得分等级划分,通过结果分析完成攀西地区矿山地质环境综合评价。论文得到以下结论:(1)在以往综合评级的工作中,都是人为主观的进行等级划分,没有科学有效的方法,本文利用多重分形方法对攀西地区地质环境质量进行评价划分,弥补了以往评价工作中的不足。(2)通过建立攀西地区矿山地质环境综合评价指标体系和评价方法体系将研究区划分为四个等级,即矿山地质环境影响严重区、矿山地质环境影响较严重区、矿山地质环境影响一般防治区和矿山地质环境非防治区,区域划分能够为矿山环境治理提供依据。
[Abstract]:With the rapid development of mining industry in China, it brings a lot of economic benefits, but also brings serious environmental problems. In recent years, mine environmental problems have become increasingly prominent. In order to coordinate the sustainable development of economy and environment, it is necessary to make a scientific evaluation of mine geological environment. Panxi region is an important metallogenic belt in China. The mineral resources in Panxi region have large reserves and various types of resources. The mineral resources have made a great deal of social and economic benefits, and the local economy has also developed by leaps and bounds. The geological hazards and environmental damage caused by mining also threaten the survival environment of local people. Combined with the mine data collected and the actual situation of the mine, the paper selects and optimizes the evaluation indexes of mine geological environment in the study area, establishes the index system at different levels, and determines the index weight through the analytic hierarchy process (AHP). The mathematical model of comprehensive evaluation of mine geological environment is established by using fuzzy comprehensive evaluation method. The comprehensive score grade of the studied area is divided by fractal, and the comprehensive evaluation of mine geological environment in Panxi area is completed by the result analysis. This paper draws the following conclusion: 1) in the past work of comprehensive rating, it is artificial and subjective to grade, and there is no scientific and effective method. In this paper, multi-fractal method is used to evaluate the quality of geological environment in Panxi area. By establishing the comprehensive evaluation index system and evaluation method system of mine geological environment in Panxi area, the research regionalization is divided into four grades, that is, the serious impact area of mine geological environment. The mine geological environment influence is serious, the mine geological environment influence the general prevention area and the mine geological environment is not the prevention area, the regional division can provide the basis for the mine environment treatment.
