基于综合判断法的矿山地质环境分区评价

Partition evaluation of mine geological environment based on comprehensive judgment method

为了对矿山地质环境进行分区,采用综合判断法,根据矿山地质环境的选择原则和特点,构建了环境治理率、水环境影响、三废排放、资源损毁、矿山开采状况、地质灾害、地质环境条件7个指标与21个指标层的评价指标体系,利用组合赋权法对指标权重值进行计算,根据矿山地质环境定量评价结果,分析分布位置、不同矿种及主要环境地质问题,将全区矿山进行划分。较轻区包括4个亚区,较严重区包括20个亚区,严重区包括10个亚区。研究对进行矿山地质环境保护及治理提了供科学依据。

In order to partition the geological environment of the mine,the comprehensive judgment method was adopted.According to the selection principle and characteristics of the geological environment of the mine,the environmental treatment rate,water environment impact,three wastes discharge,data damage,mining conditions, geological disasters,geological environment conditions were constructed.The index system and the evaluation index system of21 index layers used the combination weighting method to calculate the index weight value.According to the quantitative evaluation results of the mine geological environment,analyzed the distribution location,different mineral types and major environmental geological problems,and carried out the mines in the whole area.The lighter area included4 sub-areas;the more severe area included20 sub- areas;the severe area included10 sub-areas.The research provided a scientific basis for the environmental protection and management of mine geology.
