在对基岩破坏状态的移动形式进行分析的基础上,基于材料力学和开采沉陷学等相关理论分别建立不同的沉陷模型并推导了开采影响下岩体的移动和变形计算公式,再通过相关耦合2种介质模型,形成了双重介质下沉空间逐层传递的开采沉陷模型,同时编制了相应的计算及可视化程序。该模型不仅能够计算岩层及地表移动变形,而且能够分析计算岩层的破坏状态和断裂高度。经实测资料证明了模型的正确性和可靠性。
Based on the analysis of the mobile form of bedrock failure state, different subsidence models are established based on the relevant theories of material mechanics and mining subsidence, and the formulas for calculating the movement and deformation of rock mass under the influence of mining are deduced. Two kinds of media models form a mining subsidence model of double media sinking space layer by layer, and corresponding calculation and visualization programs are compiled. The model can not only calculate rock deformation and ground movement, but also analyze and calculate rock failure status and fracture height. The measured data prove the correctness and reliability of the model.
