摘　　要：为了准确判别辛置煤矿BT1工作面的突水水源,建立了反向模拟-聚类分析联合突水水源判别模型,研究了来自辛置煤矿4个主要含水层的39组矿井水样。研究结果表明:辛置煤矿BT1工作面的突水水源来自于石炭系K2灰岩岩溶裂隙承压含水层,突水位置位于K2含水层水样采样点附近的其他区域。在传统的聚类分析方法上增加PHREEQC反向模拟模块,旨在判别突水水源发生的具体位置,为突水水源判别提供一种新思路。In order to accurately identify the water inrush source of BT1 working face in Xinzhi coal mine,a inverse analysis-cluster analysis combined water inrush source discrimination model is established,and 39 groups of mine water samples from four main aquifers in Xinzhi coal mine are studied.The results show that the water inrush source of BT1 working face in Xinzhi coal mine comes from the confined aquifer of karst fracture of Carboniferous K2 limestone,and the water inrush location is located in other areas near the sampling point of K2 aquifer water sample.The PHREEQC inverse analysis module is added to the traditional clustering analysis method to determine the specific location of the source of water inrush and provide a new idea for the discrimination of water inrush source.
