STUDY OF FUSHUN LAOHUTAI MINERAL EARTHQUAKE ACTIVITY TREND

According to the record of mineral earthquake provided by Fushun Earthquake Bureau,earthquake study and mathematical statistics are adopted to analyze Mine Laohutai's mineral earthquake ‘b’numerical value time sequence and energy creep curve change trend.The results show that it present mining method is not changed,Fushun mineral earthquake's sacle and intensity have increase tendency for a future period of time.Applying the method of minimum two multiping and regressive,the relation expression formula between Laohutai mineral earthquake's frequency rate and magnitude are got,providing theoritecal evidence for further study of mineral earthquake's activity level.
