【Abstract】 The formula for the calculation of the coupling facter a, i.e. the ratio of seismic energy to total explosion energy, from the statistic field parameters n and k (or n, k and m) :α=(k·10-2)3/n·10-3is presented in this paper. Using the formula, we have calculated α for about 70 events. And we have found that α depends on six factors and they are the nature of the adjacent medium, the number of wells, the depths of the wells, the filling material of the well, the direction of the obsevation and the differential exciation. Finally, in order to estimate the magnitude of the explosion, we have given the following equation:M=4.42+0.53logαQwhere Q is the yield expressed in tons of TNT and a is the coupling factor calculated in this paper.更多还原
