宁夏红柳煤矿直罗组下段含水层富水性评价

             

摘要

宁夏红柳煤矿自2009年9月份开始回采以来,矿井首采工作面2#煤顶板多次发生较大规模涌水,造成了较大的经济损失。在综合分析井田水文地质条件基础上,研究影响含水层富水性的多个地学信息,确定了含水层厚度、单位涌水量、渗透系数、脆塑性岩厚度比、岩心采取率、冲洗液消耗量等6个主控因素;应用基于GIS的层次分析法(AHP),确定了各主控因素对富水性影响的权重,计算出了富水性指数,最后建立了富水性分区图,对矿井安全生产具有指导作用。%Since the winning from September 2009, several larger water inflows in the Hongliu coalmine first coal face coal No.2 roof have been happened, and caused superior economic losses. Based on the comprehensive minefield hydrogeological condition analysis, studied several geoinformation impacting aquifer water yield property, determined 6 main control factors of aquifer thickness, specific capacity, permeability coefficient, brittle rock thickness ratio, core recovery, flush fluid consumption. Using GIS based AHP deter⁃mined weight of each control factor impacting on water yield property, computed water yield property indices, finally worked out water yield property partition map. The study has guiding function in coalmine safety in production.
