The purpose of this work is to control the level of the impact of technological explosions on buildings and structures in order to ensure the safety of industrial and civil facilities. The research of the seismic effect is conducted on the historically under-mined territory of factory type. Control of the impact of explosions is carried out using a software and hardware complex created on the basis of geo-physical equipment. The complex registers the parameters of the seismic wave, then their digital processing is performed.
The article provides brief information about the deposit being developed by the mine and the history of its development. The reasons for updating the repeated studies of the impact of drilling and blasting operations on buildings and structures are described. Experimental results obtained during registration of the seismic effect from technological explosions at the "Magnetitovaya" iron ore mine are presented. The calculated values and their comparison with the current tolerances are given. Conclusions are made about the size of the impact on the objects under study. A measurement technique and subsequent processing of the data obtained are described.
