摘要(Abstract)：

针对乌海能源路天煤矿四采区南翼火点治理区存在的高温自燃、高陡边坡及复杂空巷群等极端地质条件，研究基于热-力耦合理论，开展了非常温环境下地质灾害治理的施工管理与技术机理研究。通过现场试验、数值模拟与理论分析，形成了“温度分区-热力耦合分析-差异化设计”的爆破设计方法，采用了“注水降温-凝胶隔热-PVC套管隔离”的组合防护措施与数码电子雷管精准起爆技术，揭示了温度场对岩体力学特性及爆破作用机理的影响规律，建立了考虑温度效应的岩体动态本构模型。研究提出了“温度分区-热力耦合分析-差异化设计-协同控制”的系统治理方法，构建了基于数码电子雷管的多危害效应控制体系。现场应用表明:爆破振动速度控制在0.38 cm·s~(-1)以内，飞石最大散落距离<50 m，高温孔降温治理率达100%，实现了“零伤害、零事故、零污染”目标。研究成果为非常温环境矿山地质灾害治理提供了理论依据和技术支撑。
