摘　　要：针对焦家金矿深部巷道现有支护体系无法有效防止巷道局部破坏的问题,结合岩石力学理论与工程实践展开了深入研究。通过现场调查与典型破坏模式分析,采用先进的结构面三维扫描技术,系统掌握了巷道岩体破坏特征及其成因。采用3DEC离散元软件建立了三维巷道开挖数值模型,对不同支护方案的稳定性进行了模拟分析。研究提出了具有创新性的斜交锚杆支护方案,针对巷道围岩复杂应力环境进行优化设计。数值模拟结果表明,优化后的支护体系显著提升了巷道整体和局部稳定性,有效抑制了破坏的发生,为深部巷道的安全运营提供了可靠保障。该方案不仅提升了支护效率,还降低了施工成本,为焦家金矿深部破碎巷道围岩稳定性控制提供了重要的参考和技术支持。To address the inefficiency of existing support systems in preventing localized failures in deep roadways at the Jiaojia Gold Mine,this study integrates rock mechanics theory and engineering practice.Through field investigations and analysis of typical failure patterns,advanced 3D structural plane scanning technology was employed to systematically master roadway rock mass failure characteristics and causes.A 3DEC discrete element software was used to develop a 3D numerical model for roadway excavation that simulates and analyzes the stability of various support schemes.An innovative diagonal bolt support scheme was proposed,specifically optimized for the complex stress environment of the surrounding rock.Numerical simulation results demonstrate that the optimized support system significantly enhances both global and local stability,effectively suppressing failure initiation and ensuring safe opera⁃tions in deep roadways.This solution not only improves support efficiency but also reduces construction costs,providing critical references and technical insights for stability control in fractured surrounding rock under deep mining conditions at the Jiaojia Gold Mine.
