摘要
以红岭煤矿近断层煤柱巷道为研究背景,采用理论分析、数值模拟和现场试验等手段,分析了采动影响下断层破碎带围岩应力分布规律,揭示了近断层煤柱巷道围岩应力分布演化规律及变形机理,开发了相应的巷道围岩控制技术。
Based on the background of the coal pillar roadway near fault in Hongling mine, combined with numerical simulation and field test, the stress distribution of surrounding rock fractured zone near fault under the influence of mining was analysed, the stress evolution and deformation mechanism of coal pillar roadway surrounding rock near fault was revealed, the corresponding control technology was developed.
