摘要
泊江海子矿目前主要开采3-1号煤层,通过对二盘区含水层特征、隔水层特征、含水层间水力联系及地下水补径排条件分析,确定了矿井进行煤层开采时的充水因素,并预测了矿井涌水量。此次矿井水文地质条件及充水因素分析,为泊江海子矿二盘区矿井水害防治提供了参考依据。
The Pojianghaizi Mine is currently mining the No.3-1 coal seam.By analyzing the characteristics of the aquifer in the second area,the characteristics of the water barrier,the hydraulic connection between the aquifer and the groundwater replenishment and runoff conditions,the water-filling factors of the mine when mining the coal seam were determined and the mine water influx was predicted.This analysis of mine hydrogeological conditions and water-filling factors provided a reference basis for water damage prevention and control in the mine.
