The article presents the analysis of seismic observations in mine roadways. The recorded seismic signals are connected with dynamic deformation of rock mass under massive blasting. The source of induced seismicity are dynamic movements deformation of rocks with an amplitude of 3–30 µm along fractures 1–15 m long. These events feature low values of reduced energy, probably, due to shallow depth of mining. Distribution of induced seismicity events in time and space agreed with patterns of larger seismic events due to remote earthquakes, which implies weak probability of nasty geodynamic phenomena in the course of mining in the Korobkov Field.

库尔斯克磁异常科罗布科夫铁矿场弱诱发地震

本文介绍了对矿井巷道地震观测的分析。记录的地震信号与大规模爆破作用下岩体的动力变形有关。诱发地震活动的源头是岩石沿 1-15 m 长裂缝的振幅为 3-30 µm 的动态运动变形。这些事件的特点是能量减少值较低，这可能是由于采矿深度较浅。诱发地震事件在时间和空间上的分布与偏远地震引起的较大地震事件的模式一致，这意味着在 Korobkov 油田开采过程中发生恶劣地球动力学现象的可能性很小。
