铜坑矿破碎矿柱锚注加固数值模拟研究

摘要

为了验证铜坑矿破碎矿柱锚注加固的效果,采用FLAC3D数值分析软件建立三维模型,对锚注加固的过程进行了数值模拟分析.研究结果表明,锚注加固后围岩塑性区范围及位移明显减小,锚注加固能显著提高矿柱的稳定性.%In order to verify the effect of anchoring and grouting reinforcement to broken pillars in Tongkeng mine, the reinforcement process is analyzed by numerical simulation with FLAC3D numerical analysis software. It was shown that the plastic region and displacement of surrounding rock obviously decreased after anchoring and grouting. Pillars stability can be significantly improved by the reinforcement of anchoring and grouting.
