The Application of the Magnitude Formula for Fitting Duration Time in Muchengjian Mine
Mine earthquake belongs to mine microseismic,its magnitude measurement method is the result of all kinds of calculation methods of earthquake magnitude.Based on the definition,type and classification of earthquake magnitude,in combination with mine earthquake monitoring and orientation system of Muchengjian mine,calculating mine earthquake magnitude by vibration wave duration.In order to get the duration magnitude formula which is suitable for the mine area,adopting near earthquake magnitude calculation results to fit the magnitude calculation formula.Meanwhile analyse and compare the results between the duration of the magnitude after fitting and near earthquake magnitude.The results indicate that the fitting duration magnitude formula is appropriate for mine earthquake magnitude calculation of the mine,which is of great guiding significance to Muchengjian mine of magnitude determination.
