Abstract
Production Mining Based on the Results of Seismic Measurements at the "Zvečaj" Quarry Site - A Case Study
Highlights
In order to find out about the existence of mineral deposits, it is necessary to conduct research that boils down to the selection of a geographical area based on empirical data and geological knowledge
Blasting significantly affects the environment, due to the emission of noise and seismic action, which is manifested in the form of oscillations and elastic deformations of the rock, which is an artificial earthquake in which the place of explosion is its epicenter
Seismic waves created by blasting at the "Zvečaj" quarry caused mechanical ground movements that represent non-stationary periodic oscillations
Summary
In order to find out about the existence of mineral deposits, it is necessary to conduct research that boils down to the selection of a geographical area based on empirical data and geological knowledge. It is necessary to perform preliminary research works and precise measurements of the seismic effects of test blasting in order to be able to determine the allowed quantities of explosives as reliably as possible. The degree of damage caused by this directly depends on the speed and frequency of vibrations of the building particles and the foundation soil, on the amount of explosives, the distance from the blasting site and the properties of the geological environment. Measurements were performed during production (trial) blasting at the level of the second floor, i.e. K + 163 to K + 197 m of the quarry, in order to determine the effects of seismic earthquakes on the surrounding settlements (buildings), or to determine the amount of explosive charge by ignition in order to avoid damage to nearby buildings near the quarry, [10]
