摘　　要：奥陶系灰岩突水是威胁华北矿区煤矿安全生产最严重的水害,奥陶系灰岩一般富水性强、水压高,一旦发生突水往往会对矿井造成灾难性后果.采用水文地质条件分析、水地球化学分析及数据统计分析等方法,对东坡煤矿主要充水水源水质进行了研究.结果表明,各充水水源水质差异明显,主要判识指标是Ca2+,SO24-和总硬度,并根据这些指标判断922材料巷道16号钻窝及掘进面水质与奥陶系灰岩水一致.此为东坡矿及朔州矿区首次发现奥灰出水,对矿井今后综合防治水决策及奥陶系灰岩水防治具有重要意义.Ordovician limestone water inrush is the most serious mine water accident in North China coal mine.Generally,water-abundance of Ordovician limestone is better and its water pressure is high.Once water inrush occurs,it leads to disastrous consequences in mines.This paper studied the water quality of water source of water filling in Dongpo Coal Mine by the hydrogeological condition analysis,hydrogeochemistry analysis and statistic analysis of a data method.The results show that each source of water filling has obvious differences.The main identifying indexes are Ca2 ＋,SO24-and total hardness.Besides,based on those indicators,the water quality of 922 Lane 16# drilling and innermost working face are judged to be the same with Ordovician limestone’s.The water from Ordovician limestone is the first found in Dongpo Coal Mine and Shuozhou Mining Area,which has great significance for comprehensive prevention and control of water from Ordovician limestone in future.
