摘要
本文在介绍FLAC3D数值模拟软件建模过程的基础上,结合东滩煤矿六采区实际开采条件及实验室煤岩样的物理力学试验研究,建立三维分析数值模型,通过对六采区多煤层开采,上层煤工作面推进时的应力场以及对下层煤应力分布影响的数值模拟,并综合模拟结果进行研究分析,确定应力集中区域,从而判定了冲击危险性。
The numerical simulation on the influence of stress distribution upon multi-seam mining based on FLAC3D,on the basis of dongtan mine exploitation condition and actual six mining coal rock of physics and mechanics laboratory experiments,establishing three-dimensional numerical model,through the analysis of six mining coal mining,the upper coal more working face advances to lower stress and the stress distribution of the influence of coal,and numerical simulation results of simulation analysis,determine the stress concentration region,determine the impact of risk
