Fractal Character of the Time-Space Change of Microseismicity before Coal Outbursts or Rockbursts

    摘要
  • 摘要: 矿山微震活动隐含着冲击地压趋势的信息.根据分形几何学观点研究了门头沟煤矿冲击地压发生前微震活动的时间分维特征.结果表明,冲击前微震信息的时间分维可以作为冲击地压的预测指标之一。

     

    Abstract: The some information of coal outbursts or rockbursts must be contained in microseismicity before coal outburet or rockburst in mining. In the paper, the feature of time fractal dimension of microseismicity before coal outburst or rockburst in mining is studied by using fractal geometry.It is shown that the time fractal dimension of microseismicity information before coal outburot or rockburst may be used as one of indexes of predicting coal outburst or rockburst.
