Comparison of the seismic loading of points on the surface of the Earth during a massive explosion in a mine

Abstract Geomechanical studies are performed at almost all large mining enterprises in the world. As a result of industrial activity, the Kryvyi Rih region has developed serious environmental problems. The mining of ore in Kryvyi Rih region led to the formation of numerous underground cavities. Hundreds of square kilometers of the Earth’s surface were in zones of mass collapse. Therefore, diagnosis and control of the stress state of the massif of rocks are relevant. Along with the processes of movement of underground cavities to the Earth’s surface, there is a constant threat of destruction or damage to residential buildings, violation of the integrity of the massif due to mass explosions in quarries and mines. These explosions also affect the rate at which voids emerge. This leads not only to unpredictable exits of funnels and the development of landslides, but also to the threat of rock strikes in mines. The article considers the method of measuring the vector velocity of soil particle oscillations from one source in different directions at the same time. The purpose of this article is to compare the seismic load of points on the Earth’s surface during an explosion in a mine with their orthogonal location along the directions under the conditions of destruction of the rock body in a separate area. The main task of the research was to determine the intensity of seismic explosion vibrations near the foundations of residential buildings and industrial buildings in the area of the industrial site of the mine, which were located in opposite directions. The main result of the work is obtaining a set of data related to the amplitude and frequency characteristics of seismic waves that have passed through a half-kilometer layer of rock.
