Abstract: With increasing development of digital and communication monitoring techniques, the quantity of obtained information about the damage process of rock mass around large scale mined-out areas is significantly increased. The information includes various figures and vectorgrams in digital form. Data mining and analysis for monitored breakage information from rock mass around mined-out areas using wavelet analysis, non-equilibrium statistics and neural network techniques will be beneficial to correct the understanding of the whole damage process of rock mass around min-out areas.
