中央轨道大巷出煤巷支护技术研究

Study on Central Railway Roadway Out of Coal Roadway Support Technology

针对五阳矿井7805运输巷南部的扩区中央轨道大巷出煤巷所处区域的断层、陷落柱及含水层的复杂地质条件,根据锚杆支护理论和岩石力学理论对巷道围岩稳定性进行理论分析,结合巷道围岩现有控制理论,确定出有效合理的支护方式和参数。通过现场监测数据的反馈,对围岩的支护方式和参数进行优化,从而使该区域巷道的支护参数进一步完善,保证该区域巷道的安全使用。

Based on fault and collapse column and the complex geological conditions of the aquifer in Wuyang Mine 7805 transportation roadway south central roadway coal area, according to bolt support theory and rock mechanics theory analysis on the stability of surrounding rock of roadway, combined with the existing control theory of roadway surrounding rock, effective and reasonable supporting methods and parameters were settled. Through the field monitoring data of the feedback, supporting method and parameters of surrounding rock were optimized to perfect roadway supporting parameters, which ensured safe use of the roadway.
