    Characteristics Research Of Micro-seismic Activity On Filling body Collapsing For A Lead-zinc Mine

      摘要
    • 摘要: 对某铅锌矿充填体顶板垮落事件的微震波形特征与垮落前的微震活动时空规律进行分析研究,发现充填体顶板垮落事件的震级小于-2,事件主频在300Hz左右,波形延时小于0.1s,且在垮落发生前,有48小时的地压活动孕育期与84小时的微震事件持续增长期的规律,该规律可作为未来进路开采下充填体顶板地压灾害风险评与预警的参考依据。

       

      Abstract: By researching waveform characteristics and spatiotemporal law of micro-seismic activity before filling body was collapsing, it found that the event magnitude was less than -2, dominant frequency was about 300Hz, time delay of waveform was less than 0.1s, and also found that there were 48 hours incubationSperiod and 84 hours growth period, it provided references to ground pressure risk assessment and warningSsigns for filling roof.
