基于模糊综合评判法的煤层顶板灰岩含水层富水性评价

摘要

煤层顶板含水层富水性受多因素影响，选取含水层厚度、含水层出露面积、单位涌水量、渗透系数、漏水孔率和断裂构造复杂程度等6个评价指标，建立定量与定性评价指标为一体的评价等级标准，构建基于层次分析—模糊综合评判法的煤层顶板含水层富水性多因素评价模型，并利用评价模型对贵州省黔西某矿顶板含水层富水性进行总体评价，其效果较好，可为相关研究提供借鉴。%In this paper,according to the aquifer water abundance of coal seam roof affected by many factors,the authors select the thickness of aquifer,the aquifer outcropped area,unit water inflow,permeability coefficient,water porosity, and structural complexity as evaluation indexes,and establish the evaluation grade standard combining quantitative evaluation indexes with qualitative evaluation indexes, fmailly establishes the hierarchical analysis-fuzzy comprehensive evaluation multi-factor evaluation model of the aquifer water abundance of coal seam roof,evaluate the aquifer water abundance of coal seam roof of a mine in Qianxi,Guizhou province on the overall by using the evaluation model,the effect is good,it can provide reference for future related research.
