摘　　要：矿井水害是影响煤矿安全生产和建设的重要因素,本文从慈林山煤矿水文地质条件、补给条件、充水条件等入手,分析了突水危险性,提出防治措施。结果表明:矿井充水水源主要为大气降水、第四系松散岩类孔隙含水层、石炭系上统太原组岩溶裂隙含水层水、采空积水等;构造(断层、陷落柱)和导水裂隙带为导水通道,15号煤层庄头断层以西(上盘)部分区域低于奥灰水的煤层存在带压开采,带压地段存在奥灰水突水可能性,划为禁采区。Mine water disaster is an important factor affecting coal mine safety production and construction.This paper analyzes the risk of water inrush from the hydrogeological conditions,recharge conditions and water filling conditions of Cilinshan Coal Mine,and puts forward prevention and control measures.The results show that the mine water filling sources are mainly atmospheric precipitation,Quaternary loose rock pore aquifer,Carboniferous Taiyuan Formation karst fissure aquifer water,goaf water and so on.The structure(fault,collapse column)and water-conducting fracture zone are water-conducting channels.The coal seams in the west of Zhuangtou fault(upper side)of No.15 coal seam are lower than Ordovician limestone water,and there is a possibility of water inrush from Ordovician limestone water in the pressure section,which is classified as area.
