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.
