Study on Stress Field Distribution Regularity of Primary Mining Face Based on Numerical Simulation

依据米箩煤矿开采工艺、煤岩物理力学参数试验等基础资料,采用FLAC^(3D)软件建立数值模型,通过选取不同阶段的垂直应力云图可以对比研究分析得出厚基岩浅埋煤层首采工作面的应力场分布规律。此外,FLAC^(3D)软件能够更好地模拟出煤岩应力场,可以为矿井安全生产提供理论指导。

According to the basic data on the mining technologies of Miluo coal mine,coal and rock physical mechanics parameter test data,then FLAC3D software is adopted to establish the numerical model. By choosing vertical stress nephogram for different stages can research contrastively and then analyze the stress distribution rule for a initial mining working face of thick bedrock shallow and buried coal seam.Besides,FLAC3D software can better simulate the coal and rock stress field, and provide theoretical guidance for mine safety production.
