摘要
针对火石咀煤矿的重型综放支架回撤问题进行了研究,首创并成功实施了无预留回撤通道快速撤除技术。通过实际应用总结了该技术的工艺流程、前期准备和安全防范措施,并系统分析了其技术安全经济效益,为重型综放面支架回撤提供了经验。
Based on heavy caving bracket retracement conduction study in Huoshiju mine, without reservation retracement channel fast removal technologies were pioneered and successfully implemented. The practical application of the technology process, preparation and safety precautions were was summed up. The system safety analysis of its technical economic benefits provided experience for caving face heavy bracket retracement.
