摘　　要：本文通过对霍西、沁水煤田的成煤环境,水文地质条件,以及矿井生产过程中防治水的实例研究,综合运用工作经验及理论知识,客观分析了煤矿生产特别是开采下组煤时所面临的主要水害、各水患的涌水通道以及充水条件,针对上组煤采(古)空积水、下伏奥灰含水层的带压开采等水害,提出了相应的防治措施,为避免煤层开采时可能受到的水患影响,探索其存在及变化规律,进而为提出合理化建议提供参考。Based the coal forming environment,hydrogeologic condition and water control case of Huoxi and Qinshui coalfield,this paper analyses the main water disaster,water inflow channel and water filling condition in coal mining,especially lower group coal mining.Then the corresponding prevention and control measures are put forw ard for water accumulating in upper mine gob and underlying Ordovician aquifer.It explores the law of water disaster in coal mining,which can provide references for water disaster prevention and control.
