金属矿山顶板冒落安全机理及预警系统研究

Research on Security Mechanism and Early Warming System of Roof Fall in Metallic Mines

运用故障树分析法,找出了金属矿山顶板冒落事故中最重要的基本事件,同时又利用GM(1,1)以及声发射技术建立了顶板冒落事故预测模型,并根据上述理论,对矿山顶板冒落的安全评价以及预测信息系统进行了开发研究。

The most main basic events for the roof fall accident are found by mean of fault tree analysis（FTA） technique. Moreover,a prediction model of roof fall accident is established using GM （ 1,1 ） model and acoustic emission. Finally, based on these theoretic studies, a safety assessment and prediction information system of roof fall for mine is studied and developed.
