摘要
建立陷落柱流固耦合模型和对应的数值模拟计算模型及陷落柱充填物孔隙率的随机分布,通过有限元多物理场耦合软件COMSOL Multiphysics对力学模型进行模拟计算,然后分析不同时间点上的陷落柱压力分布云图和不同时刻的剪切力的分布云图及其对应曲线,分析发生突水事故的各种因素,对矿井预防突水事故发生有一定的作用。
In the establishment of simulation model and the random distribution of collapse collapse column filling porosity numerical column fluid solid coupling model and the corresponding, mechanics model of simulation by finite element multiphysics coupling software COMSOL Multiphysics, and then analyze the distribution of column pressure distribution and different moment shear force and the corresponding curves fall at different time points the analysis of various factors of water inrush accidents, water inrush accident has a certain effect on the prevention of coal mine.
