摘　　要：岱河矿区地下水系统包含三个主要子系统:第四系全新统孔隙含水层、煤系砂岩裂隙含水层组及煤系下伏灰岩岩溶裂隙含水层组。通过对矿区三个子系统地下水化学特征分析,确定各子系统涌出水来源判别依据的水溶组分并建立各子系统所特有的水质模型,进而提出矿井涌水水源判别模式。实际应用表明,该判别模式具有快速准确的特点,可以为了解矿井涌水来源,预测矿井涌水量,防治矿井突水提供理论依据。The groundwater system in the Daihe coalmine consists of three main subsystems： Quaternary Holocene porous aquifer, coal measures sandstone fissure aquifer group and coal measures underlying limestone karstic fissure aquifer group. Through three subsystems groundwater hydrochemical characteristics analyses have determined water soluble aonstituents as criteria to identify water inrush source from which subsystem and establish each subsystem particular water quality model, and then provide coalmine water inrush source discrimination model. Practical application has demonstrated that the discrimination model has characteristics of highspeed and accurate, can provide theoretical bases to know mine water inrush source, predict mine inflow and control mine water bursting.
