Active development of quarries in the Republic of Karelia contributes to the improvement of the control system of the parameters of drilling and blasting operations with the aim of ensuring the safety of buildings and structures near mining facilities.

In the quarries of the Kostomuksha mining and processing plant, to reduce the seismic effect, short-blasting is used. The created monitoring system in Karelia makes it possible to select not only teleseismic earthquakes, but also regional and local scale events on the seismic records. Explosions are recorded by seismic stations of the Karelian network and other regions if the magnitude of the event is more than 1.7.
