摘要：In recent years, Along with the upper part coal resources dried up gradually in our country, it is most necessary to mine deep coal seam. Deep coal seam mining is threatened by water hazards, study on Fluid-Solid Coupling of Deep Well Rock will provide a theoretical support with Deep Mine Water Disaster. This paper analyzed interaction between Seepage Field and Stress Field in Coal Bed Floor Rock Mass. Set up a numerical model of coal mine upper confined water, and the regularity of the Floor Failure with the mining process is analyzed, Simulated Study on the law of Coal Bed Floor Rock Mass Failure and analysis of Coal Floor Fluid-Solid Coupling are based on Mining Depth and Water Pressure. © 2015 ejge.
