摘　　要：本文在研究桃园煤矿Ⅱ1028工作面地质条件及水文地质特征的基础上,对桃园煤矿Ⅱ1028工作面突水特征、水化学特征、含水层水位动态变化进行分析,并进行突水水源识别。结果表明,突水水质与10煤上下砂岩裂隙含水层、太灰含水层的水质相关,说明突水水源主要是来自于10煤上下砂岩裂隙水,太原组灰岩含水层是主要补给水源。Based on the study of the geological conditions and hydrogeological characteristics of Ⅱ1028 working face in Taoyuan Coal Mine,this paper analyzed the water inrush characteristics,hydrochemical characteristics,and the dynamic change of aquifer water level of Ⅱ1028 working face in Taoyuan Coal Mine,and identifies the water inrush source.The results show that the water quality of the water inrush is related to the water quality of 10 coal upper and lower sandstone fracture aquifer and Taiyuan limestone aquifer,indicating that the water inrush source is mainly from 10 coal upper and lower sandstone fracture water,and the limestone aquifer of Taiyuan formation is the main supply water source.
