摘要:
应用三维弹性中厚板理论，分析了采动与承压水耦合作用下煤层底板的力学效应及破坏机理。基于Hamilton原理推导了采空区底板在采动和水压耦合作用下的变形和应力表达式，分析了其变形和应力的分布特征。最后，推导了在采动与承压水耦合作用下煤层底板破坏极限载荷PS，讨论了影响煤层底板破坏极限载荷PS的因素。研究成果对揭示回采工作面开采时煤层底板隔水层变形破坏，预防煤层底板突水提供了理论依据。
Abstract:
The theory of three-dimensional elastic plate was applied to analyze the mechanical effect and damage mechanism of coal seam floor under the coupling action of mining and confined water. The expressions of deformation and stress for goaf floor under the coupling action of mining and water pressure were deduced based on the Hamilton theory, and the distribution characteristics of deformation and stress were analyzed. At last, the damage limit load PS of coal seam floor under the coupling action of mining and confined water was deduced, and the factors influencing PS were discussed.The research results provided a theoretical basis for revelation of the deformation and failure of coal seam floor in the mining of mining face and prevention of water inrush from coal seam floor.
