摘要
针对东滩煤矿陷落柱柱体剖面揭示的形态学特征,为研究采动压力和渗透水压对陷落柱渗流突水的作用,建立了采场底板陷落柱突水的物理模型,并利用FLAC3D软件模拟分析了采场推进过程中应力场和渗流场的变化特征;通过模拟分析再现了陷落柱周边岩体破坏、损伤、渗流、突水通道形成的全过程,揭示了采场底板陷落柱渗流突水机理。
In order to study the morphological characteristics of the collapse column of Dongtan coal mine, the physical model of the water inrush from the bottom plate of the stope was established by studying the effect of the mining pressure and the infiltration pressure on the seepage and water inrush. The simulation results show that the deformation and damage of seepage passages, seepage and seepage passages in the surrounding rocks are simulated and analyzed. The results show that the seepage water bursting mechanism.
