| 摘 要： | 永夏矿区矿井生产受到太原组灰岩水的严重威胁,特别是底板裂隙引起的灰岩突水更是严重影响矿井安全生产和经济效益。根据裂隙切割底板隔水层引发突水的情况,把底板裂隙突水分为导通式裂隙突水和递进导升式裂隙突水两种类型,并利用Flac3d软件对这两种类型的突水机理进行了模拟研究,为底板裂隙突水的防治提供了一定的理论依据.

| Abstract: | Carboniferous limestone water has threatened the mine production in Yongxia mining area, especially water inrush from limestone floor caused by coal floor fissure seriously affected the mine safety production and economic benefits. Base on the condition of water inrush caused by fissure which has cut the coal floor aquiclude, water inrush from coal floor fissure has been classified into two types: through leading fissure and through growing fissure。 Numerical simulation has been carried on to study the mechanism of the two types water inrush by Flac3D. The research can provide the certain basis for the prevention of water inrush from coal floor fissure. |
