摘　　要：近年来,矿井突水事故频发,高水压灰岩含水体对煤层的安全开采带来极大的威胁.本文以袁店煤矿10煤层底板太原组灰岩上段含水层为例,在收集钻孔和抽水试验等相关资料基础上,从充水水源、充水通道及涌(突)水量预计三个方面,进行充水条件分析.研究结果表明该含水层段存在突水的可能,对进一步防治水设计提供参考依据.In recent years,the mine water inrush accidents occur frequently.Limestone aquifer with high pressure has a great threat to safe mining of coal seam.Taken upper limestone aquifer under No.10 coal seam of YuanDian coal mine as an example and based on the collection of drilling and pump test data,water-filled conditions was analyzed from water filled source,channel and estimation of water discharge.The research results show that the water inrush in the aquifer is likely to provide a reference for the further prevention and control of water design.
