摘要
针对塔然高勒煤矿西一盘区3-1煤层顶板含水层涌水危险性问题,利用聚类分析对含水层厚度、岩芯采取率、脆塑性岩厚度比、渗透系数、单位涌水量等关键因素进行涌水分区,并结合模糊综合评判法对各涌水分区进行等级划分,将其划分为“安全”“较安全”“较危险”“危险”4个等级。结果表明,西一盘区可分为6个分区,除F分区为危险区外,其余分区均为安全区,与西一盘区实际水文地质条件相一致。基于聚类分析的模糊综合评判法可作为煤层顶板涌水危险性评价方法。
In view of the risk that roof water inrush from 3-1 coal seam in the west panel of Tarangaole Coal Mine,the key factors such as aquifer thickness,collecting rate of drill core,thickness ratio of brittle-plasticity,permeability coefficient and units-inflow were analyzed by cluster analysis to water inrush partition,by using fuzzy comprehensive evaluation method,it can be divided into four grades of“secure”,“relatively secure”,“relatively dangerous”and“dangerous”.The results show that it is divided into 6 zones,the F zone is“dangerous”and the rest zones are“secure”,which is in accordance with the actual hydrogeology condition.The fuzzy comprehensive evaluation based on cluster analysis can be used to assess the risk of roof water inrush.
