摘　　要：根据采动岩体渗流力学的观点,矿井突水溃沙是液固两相流失稳的体现。基于CFX数值模拟软件建立裂隙水沙两相流数值模型,通过模拟与分析得到裂隙尺寸、沙颗粒直径和液相流速对压力梯度、时均速度分布和湍动能的影响规律。According to the theory of seepage mechanics of the mining rock, the water bursting of the mine is the embodiment of the steady flow of liquid solid. Based on CFX numerical simulation software to establish a fissure water two phase flow numerical model, fracture size is obtained by simulation and analysis, the sand grain diameter and liquid velocity of pressure gradient, the influence law of velocity distribution and turbulent kinetic energy.
