| 摘 要： | 为提高利用地音数据预测预报矿井冲击矿压的水平,从能量释放方式角度深入分析了煤岩体破坏过程中的3种演化可能,提出了基于地音事件加权平均能量值的分析方法,并阐明了分析步骤.利用某矿ARES-5/E地音监测系统实测数据进行验证,结果表明该方法能够准确对微震事件和冲击事件进行预警,且微震事件的超前预警事件相对冲击事件的预警事件...

| Abstract: | In order to improve forecast and prediction level of rock-burst by applying earth acoustic data,this paper analyzed 3 evolvement possibilities in coal and rock damage from energy release view.It put forward analysis method based on weighted average value of earth acoustic matters and introduced analysis process.This method was verified by actual measurement data from ARES-5/E system.Results showed that this method could accurately predict micro-seismic matters and rock-bursts.Prediction time of micro-seismi... |
