Abstract: The article presents the results of research, which consist in studying the features of the spatio-temporal propagation of seismic waves from technological blasts, according to the data obtained by seismic recorders installed on the earth's surface, to increase the level of safety of protected facilities, the stability of slopes and more rational use reserves of mineral deposits in the near-edge zone developed by the open method. To achieve this goal, the main objectives of the study were solved, i.e. the seismic effect of technological blasts on protected facilities and the near-edge rock masses in various mining and geological conditions of complex-structured deposits of the Urals, Siberia, Karelia and Kazakhstan was studied using direct field measurements; the analysis of the deviations of the actual rock mass vibrations from the calculated values at different coefficients of soil conditions was carried out, and clarifying dependences for calculating the permissible vibration rates of the rock mass based on the physical and mechanical properties of rocks with their different structural weakening were obtained; on the basis of data on the properties of rocks and the propagation of seismic vibrations in them during large-scale blasts, an express method has been developed that allows determining the earthquake-safe parameters of drilling and blasting operations in the near-edge zone of the quarry, to ensure the stability of slopes, as well as to predict the seismic impact of the blasting operations on protected facilities.

Keywords: oscillation rate of the rock mass, seismic impact, seismic, blasting, structural weakening of the rock mass, strength characteristics of rocks, slope stability in quarries
