大采高沿空巷道围岩稳定性数值模拟

Numerical Simulation on Surrounding Rock Stability of Gob-side Entry in Large Height Mining Face

  • 摘要: 为研究影响大采高工作面沿空巷道围岩稳定性的主导因素,以羊场湾矿130205沿空巷道为工程背景,运用FLAC3D数值模拟软件,探究煤柱宽度、工作面采高及采动剧烈程度对沿空巷道围岩稳定性的影响规律。研究表明:煤柱宽度、采动剧烈程度对围岩稳定性影响较显著,采高的影响程度相对较小,且沿空巷道围岩应力和变形分布呈明显不对称性,并随煤柱宽度的减小、采动强度的递增愈加显著。
    Abstract: In order to study the leading factors affecting the stability of surrounding rock in gob-side entry at large height mining working face, taking 130205 gob-side entry in Yangchangwan Mine as an example, based on FLAC3D numerical simulation software, the influence laws of the coal pillar width, the height of the working face and mining strength on the stability of the surrounding rock are explored. Research shows that the influential intensity of the coal pillar width and mining strength are stronger than the height of the working face, and the stress and deformation distribution of surrounding rock is obvious asymmetry. The asymmetry is more obvious when the width of the coal pillar is smaller and the mining strength is stronger.
