分析了开采扰动对贯穿陷落柱不稳定渗流所引发突水的影响效果。利用应力和渗流耦合方程来模拟渗流规律,运用FLAC3D模型进行数值模拟从而确定剪切应力、损伤区、渗流矢量对渗流场的影响效果。
Analyzes the effect of mining disturbance on the water inrush caused by the unsteady seepage through the penetrated karst collapse pillar. The coupling equations of pressure and seepage flow are used to simulate the seepage flow. Numerical simulation is carried out using FLAC-(3D) model to determine the effect of shear stress, damage zone, seepage vector on the seepage field.
