水质特征模型在下组煤首采面突水水源判别中的应用

The Application of Water Feature Model for Water-bursting Source Judgment at the First Mining Face of Under-group Coal Seams

摘要: 通过对淄博矿业集团公司岱庄煤矿影响下组煤开采的3个主要含水层以前所做的大量水质化学成分化验结果的资料整理,建立了该矿下组煤主要充水水源的水质特征模型。根据最近突水点水质特征指标与已建立的水质特征模型进行综合对比,准确及时地确定了突水水源。

Abstract: Through processing the large number of water quality chemical composition test results of three main aquifers,which affect the under-group coal mining at Daizhuang coal mine of Zibo mining group,the water feature model of mainly water filling resource in the under-group coal seam is established.According to the comprehensive comparison between the water feature indexes of a recent water bursting point and the established water feature model,the source of bursting water is determined timely and accurately.
