摘要
在研究孙疃煤矿地质条件及水文地质特征的基础上,对1028工作面底板突水特征、水化学特征、含水层水位动态变化,得出1028工作面突水水源主要来源于10煤上下砂岩裂隙水,太原组灰岩上、中含水层段水是主要补给水源,与第四含水层和太原组灰岩下含水层段无关。
On the basis of geological conditions and hydro-geological features in Suntuan Coal Mine, combined with analysis of characteristics of water inrush from the floor of No. 1028 longwall, conventional plasma chemical characteristics of water samples, and dynamic changes of water level in aquifer, it was concluded that inrush water source is mainly from sandstone fracture aquifer above and below No. 10 coal seam. upper-aquifer and middle-aquifer of Taiyuan formation limestone are the main source of water supply, and it is independent of?? the fourth aquifer and lower-aquifer of Taiyuan formation limestone.
