Abstract—The spatial distribution of the triggered seismic events in mining conditions in the tectonically loaded rock masses is studied using the example of seismicity in the Khibiny Mountains. It is shown that the distribution of distances from the triggering to triggered events, on average, obeys the power-law with a parameter independent of the magnitude of the triggering event. The model of the maximum distances from a triggering event’s hypocenter to the triggered shocks expected with a given probability is derived. It is shown that the model is consistent with the real data. Based on the error diagram analysis, the guidelines are proposed for the practical use of the model.

摘要——以 Khibiny 山脉的地震活动为例，研究了在构造加载的岩体中采矿条件下触发地震事件的空间分布。结果表明，从触发事件到触发事件的平均距离分布服从幂律，其参数与触发事件的幅度无关。推导出从触发事件的震源到以给定概率预期的触发冲击的最大距离模型。表明模型与真实数据一致。在误差图分析的基础上，为模型的实际应用提出了指导方针。
