摘要

本文介绍了古布金铁矿爆破破碎过程中大块爆破对古布金市地震影响的监测结果。得到了地震爆炸波的最大振荡速度与减小的震源距离(基于延迟阶段炸药的质量)的关系。对于其中一次大爆炸，绘制了等震图，显示了地震对城市居民区的影响强度。考虑到规范性文件的要求以及地震和爆炸振动的持续时间，对人口的地震振动的允许速度和最大允许速度进行了估计。

Seismic Impact of Bulk Blasts during Underground Mining of the Korobkovsky Iron Ore Deposit on Buildings and Population of the City of Gubkin

The article presents the results of monitoring the seismic impact of bulk blasts during explosive breaking of iron ore in the Gubkin mine on the city of Gubkin. The dependence of the maximum oscillation velocity in a seismic explosion wave on the reduced (based on the mass of the explosive in the delay stage) hypocentral distance to the explosive chamber is obtained. For one bulk blast, an isoseist map was constructed, demonstrating the intensity of seismic impact on residential areas of the city. Taking into account the requirements of regulatory documents and duration of seismic and explosion vibrations, estimates of the permissible and maximum permissible velocities of seismic vibrations for the population have been obtained.

期刊介绍： Seismic Instruments is a journal devoted to the description of geophysical instruments used in seismic research. In addition to covering the actual instruments for registering seismic waves, substantial room is devoted to solving instrumental-methodological problems of geophysical monitoring, applying various methods that are used to search for earthquake precursors, to studying earthquake nucleation processes and to monitoring natural and technogenous processes. The description of the construction, working elements, and technical characteristics of the instruments, as well as some results of implementation of the instruments and interpretation of the results are given. Attention is paid to seismic monitoring data and earthquake catalog quality Analysis.
