| Abstract: | According to earthquake data of Fushun earthquake administration，the seismic analysis and statistical methods are utilized in order to analyze earthquake frequency，“b”-value timing and energy creep trends in Laohutai coal mine． By using least squares linear regression method，the relational expression between frequency and magnitude of mine earthquake in Laohutai coal mine is given． And the possible largest magnitude mine earthquake inferred has also been calculated． And this paper also provides a theoretical basis for further study of mine earthquake activity． |
