随着开采深度的不断增加，一些深部的矿井正面临高承压水上采煤的现状，针对这一现状结合对底板突水机理的分析，利用FLAC30软件强大的流固耦合功能，对高承压水上开采工作面进行流固耦合数值模拟，分析和研究煤层底板岩层在采动过程中的位移、应力及孔隙水压力变化规律，并得出了某煤矿9#煤层962工作面底板的破坏深度．结合突水系数法对该工作面带压开采的可行性进行分析，为工作面的正常开采提供理论依据．

With increasing depth of mining, a number of deep mines with high pressure water is facing the current situation of high pressure water mining. Based on the analysis of water inrush mechanism of response to this situation, this paper takes advantage of FLAG3D software, which is a powerful fluid - structure interaction function, and makes a numerical simulation of fluid - structure interaction of high - pressure water mining. It also analyzes and studies the coal seam floor strata in the mining process of displacement, stress and pore water pressure variation, and obtains the depth of the destruction of the 9# coal mine of the working face floor. It makes a feasible analysis of the mining face pressure by using the sudden water coefficient method, and provides a theoretical basis for the normal exploitation of the working face.
