| 摘 要： | 本文提出爆炸地震的能量转换系数计算公式 α=(k·10-2)3/n·10-3和 α=2.03·10-3 multiply from i=1 to 6 （Fi）上式中k、n为爆炸地震效应的统计参数。下式中Fi（i=1,2,…,6）为反映爆炸方式和场地条件的影响因子。 利用爆炸地震的能量转换系数α,还可建立不同爆炸方式的药量等效系数η: η=α/α0和爆炸震级估算公式 M=4.42+0.53logαQ.上式中α0为井下组合（标准）爆破的转换系数。下式中Q为以吨（t）为单位的药量（TNT）。

| 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. |
