基于对断层形态、产状要素、力学性质及断层导水性质的认识,分析了断层突水通道形成的影响因素,认为在水压与多次应力的作用下,裂隙的导水性变化与时间存在指数关系;给出了突水量预测的变参数渗流模型,并对赵各庄矿9水平东翼石门突水事故的突水量进行了模拟.计算结果表明:与一般渗流模型相比,变参数渗流模型能够模拟出突水量的变化过程,用于描述滞后突水或涌水具有合理性,更适合于分析突水水源、突水通道及突水量之间的变化关系.
Based on the knowledge of fault shape, element, mechanical property and fault conductivity, the factors affecting the formation of water inrush fault were analyzed. Under the action of water pressure and multiple stress, the change of water conductivity and the existence of time And the relationship between the water inrush and water inrush is also given.A model of variable parameter seepage with water inrush forecast is given and the water inrush from 9 water level in the east gate of Zhaogezhuang Mine is simulated.The calculation results show that compared with the general seepage model, The model can simulate the process of water inrush, which is reasonable to describe the water inrush or gushing water. It is more suitable for analyzing the relationship between water inrush, water inrush and water inrush.
