【摘要】：隨著我國礦業(yè)的快速發(fā)展,在帶來大量的經(jīng)濟效益的同時,也伴生出了嚴(yán)重的環(huán)境問題。近幾年,礦山環(huán)境問題日益突出,為了協(xié)調(diào)好經(jīng)濟與環(huán)境的可持續(xù)發(fā)展,需要對礦山地質(zhì)環(huán)境做出科學(xué)的評價。攀西地區(qū)是我國重要的成礦帶,該區(qū)礦產(chǎn)資源儲量大、資源類型多樣,由礦產(chǎn)資源取得了大量的社會經(jīng)濟效益,當(dāng)?shù)亟?jīng)濟亦得到了突飛猛進的發(fā)展,而礦山開采帶來的地質(zhì)災(zāi)害和環(huán)境破壞也同時威脅著當(dāng)?shù)氐娜嗣竦纳姝h(huán)境。文章結(jié)合收集到的礦山相關(guān)數(shù)據(jù)和礦山的實際情況對研究區(qū)域內(nèi)礦山地質(zhì)環(huán)境評價指標(biāo)進行篩選與優(yōu)化,分層次建立指標(biāo)體系,通過層次分析法確定指標(biāo)權(quán)重,利用模糊綜合評價法建立礦山地質(zhì)環(huán)境綜合評價的數(shù)學(xué)模型,通過分形對研究區(qū)域進行綜合得分等級劃分,通過結(jié)果分析完成攀西地區(qū)礦山地質(zhì)環(huán)境綜合評價。論文得到以下結(jié)論:(1)在以往綜合評級的工作中,都是人為主觀的進行等級劃分,沒有科學(xué)有效的方法,本文利用多重分形方法對攀西地區(qū)地質(zhì)環(huán)境質(zhì)量進行評價劃分,彌補了以往評價工作中的不足。(2)通過建立攀西地區(qū)礦山地質(zhì)環(huán)境綜合評價指標(biāo)體系和評價方法體系將研究區(qū)劃分為四個等級,即礦山地質(zhì)環(huán)境影響嚴(yán)重區(qū)、礦山地質(zhì)環(huán)境影響較嚴(yán)重區(qū)、礦山地質(zhì)環(huán)境影響一般防治區(qū)和礦山地質(zhì)環(huán)境非防治區(qū),區(qū)域劃分能夠為礦山環(huán)境治理提供依據(jù)。
[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.
