辽宁鞍山地区基于层次分析法的矿山地质环境评价

摘要

鞍山地区矿山开发程度高,矿山地质环境问题严重,管护工作难度大.利用层次分析法,构建以鞍山地区矿山地质环境评价为目标的三级评价指标体系,确定评价指标权重,分析各指标相对于目标的影响强度,获得鞍山地区矿山地质环境综合指数分布特点,将鞍山地区矿山地质环境划分为较差区、一般区、较好区3个级别.结果表明层次分析法应用于矿山地质环境评价是比较合理、有效的,其评价分区的划分为矿山地质环境管护工作提供了可靠的基础数据依据.%Due to intensive mining operation in Anshan iron deposit area,it results in seriously mine geological environment problem,thus it is very difficult to carry out mine management and geological environmental protection work.Using analytical hierarchy process (AHP),taking mine geological environment evaluation as target layer,constructing three-level evaluation index system,determining the weight of each index layer and analyzing the effect intensity on the target layer.According to the characteristics of index distribution,the mine geological environment quality of Anshan area is divided into three levels,i.e.,poor area,general area and good area.The result shows that AHP in mine geological environment evaluation is reasonable and effective,and it cau provide reliable base data for mine geological environment management and protection work.
