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。
The mine production in Yongxia Mining Area was seriously threatened by the limestone water in Taiyuan Group and specially the limestone water inrush from the floor cracks were seriously affected to the mine safety production and the economic benefits. According to the water inrush conditions from the cracking floor of the water isolated layer, the water inrush from the floor cracking could be divided in to two types and they were water flow type cracking water inrush and the progressive guided increased type cracking water inrush. The FLAC3D software was applied to the simulation study on the water inrush mechanisms of the two types, which could provide the certain theoretical basis to the prevention and control of the floor cracking water inrush.
