Partition Prediction Model for Hidden Danger of Roof Fall and Its Application Practice

  • 摘要: 为解决井下大断面巷道的支护安全问题,参考行业内学者对巷道冒顶机理和顶板稳定性影响因素研究理论,将数学分析和实测考察相结合,通过层次分析法、加权平均法处理不同因素对顶板稳定影响权重;建立指标量化准确、考察简便、层次清晰的顶板稳定性评价体系和冒顶隐患分区预测模型;经过锦界矿开切眼应用实践,该方法预测分级准确,可对薄弱危险区域支护进行针对性的补强完善。
    Abstract: To solve the problem of supporting safety of underground tunnels with large sections, referring to the research theories of the influencing factors of roof fall mechanism and roof stability by scholars in the industry, combining mathematical analysis with actual observations, analytic hierarchy process and weighted average method are used to deal with different factors affecting the stability of the roof stability, a roof stability evaluation system with accurate quantification, simple inspection, and clear hierarchy of indicators is established, and a partition prediction model is designed. After the opening practice of Jinjie Mine, this roof stability prediction method is accurate, it can reinforce the targeted support measures for the existing dangerous areas with weak roadway.
