刘店矿太原组1-4灰岩含水层径流强弱模糊综合评判

淮北刘店矿主采煤层10煤层位于太原组灰岩含水层上,岩溶径流强弱的研究对煤矿安全开采而言具有重大意义。文章在分析地下水中常规离子(Ca2+,Mg2+,SO42-,HCO31-等)、岩溶发育情况及单井涌水量(q)和岩溶径流的强弱相互联系的基础上,采用模糊综合评判1]对井田岩溶径流带的强弱进行分区综合评判,为矿区开采规划提供决策依据。

Blurry and Synthetical Estimation of Taiyuan 1-4 Limestone Aquifer Runoff Strength in Liudian Coal Mine

In Liudian Coal Mine of Huaibei,the primary mineable coal bed,10 mineable coal bed,is located on limestone aquafer of the Taiyuan group,so the research on strong or weak of the karst runoff has a great meaning to the coal mine safety mining.Based on the interassociation of analyzing the conventional ions(Ca2 ,Mg2 ,SO2-4,HCO31-and so on) in groundwater,developmental state of karst,single-well water inflow(q) and strong or weak of the karst runoff,using the Fuzzy Comprehensive Evaluation,had a practical comprehensive evaluation to the strong or weak of the karst runoff zones of coal mining fields,which provide decision-making basis for mining in the coal mine district.
