摘　　要：针对煤层顶板突水模型实验中顶板岩层破坏,建立流固耦合控制方程,结合Comsol Multiphysics与MATLAB对控制方程进行编程模拟,模拟结果得出在不同的应力条件下,顶板岩层出现沉降、离层以垮塌突水的整个过程;并很好的模拟出在突出过程中水流速度场的分布情况。将模拟结果同做过的实验检测数据进行对比,吻合程度较好,表明此模型正确的模拟了矿井突出的整个过程。In view of roof strata destruction in experiment of the coal seam the floor gushing water model,establish fluid-structure coupling control equation.Simulate the control equation of programming in combination with Comsol Multiphysics and MATLAB.The simulation results in roof strata subsidence abscission collapsed in the whole process of water inrush under different stress conditions are obtained.And well simulate the distribution of flow velocity field in the process of outstanding.Compare to the experimental testing data the simulation results done better,which shows that this model is correct simulated the whole process of the floor gushing water.
