华东地区矿山地质环境定量评价研究
|
摘要
根据华东地区各省矿山地质环境调查资料,从矿山区域条件、矿山开采对矿山地质环境的影响程度、矿山地质环境问题的发育程度、矿产资源开发规划、矿山生态环境恢复治理的难易程度等5个方面确定了影响矿山地质环境的指标体系,建立了矿山地质环境定量评价模型。该模型有16个评价指标,涵盖了影响矿山地质环境的各种因素。在GIS软件辅助与专家干预下,对16个评价指标逐一开展了评价工作,并在专家打分的基础上,运用层次分析法确定了各评价指标的权重值。根据各指标的评价结果及相应的权重值,计算得出总体评价的分值。在专家干预下利用MAPGIS软件编制了华东地区矿山地质环境评价图。经野外验证,评价结果与实际情况较为吻合。
This paper has determined the index system that produced influence on mining geo-environment,and has established the quantity evaluation model from the following aspects:mining area conditions,the extent of mining geo-environmental impact of mining,the degree of development of geological problems,exploration planning of mineral resources,and how easy it is to recover and rehabilitate mine environment.This model has 16 evaluation indexes,covering the influence of various factors of mine geological environment.Under the assistant of GIS software and expert intervention,the 16 evaluation index is evaluated one by one;and based on the expert scoring,using the AHP to fix on the authority of indexes.According to this,the overall evaluation score is calculated.With the expert intervention,by using MAPGIS software,the graph of mine geological environment assessment for eastern China is prepared.Being verified by the field investigation,evaluation result is coincident with the reality.
