摘　　要：基于渗流-应力耦合理论,建立流-固耦合数学模型;通过多物理场全耦合分析软件Comsol Multiphysics对某矿3302工作面进行了数值模拟,研究煤层底板应力和底板所承受水压力情况,从而确定底板突水危险性。Based on the theory of seepage-stress coupling, a mathematical model of fluid-solid couplingis established. The multi-physics full-coupling analysis software Comsol Muhiphysics iS used tosimulate the 3302 working face of a mine, and the stress of the bottom of the coal seam and the waterpressure of the bottom plate are studied, determine the risk of floor water inrush.
