层次分析法在煤矿地质环境影响程度预测评估中的应用

Application of AHP in the Assessment about Coal Mine Geological Environment

以禾草沟煤矿地质环境影响程度分级分区预测评估为例,采用层次分析法进行预测评估,首先进行评估因子的确定,然后确定各评价单元的地质环境影响程度指数D,根据该指数进行评估区分区分级,最后确定地质影响严重区、较严重区和较轻区。

This paper takes the hierarchical partition prediction evaluation of geological environment impact degree in Hecaogou coal mine as the example uses analytic hierarchy process to carry out the forecastion and evaluation. First, the evaluation factor is determined, and then, D the geological environment impact degree index of each evaluation unit is determined. According to the index, the zoning and grading of evaluation area are carried out. The most serious area, more serious area and lighter area of the geological influence are determined.
