Abstract

The drilling and blasting method of rock destruction is the most effective and the only possible method for the destruction of strong ores and rocks. The efficiency of the explosive preparation of the mineral resource and the surrounding rocks for excavation determines the technical and economic indicators of the drilling and blasting complex, the productivity and safety of the following mining processes and the entire enterprise. The main method of explosive preparation of the rock mass for excavation is the production of mass explosions of well charges. Total mass of explosives The explosive capacity is 50-300 tons, and in some cases reaches 700 tons. Such a weight The blasting headquarters refers to both the open mining method and the underground one. Recently , concentrated charges in rising workings with a mass of have become widely used in underground mining 20 – 30 t and in beam well charges 2 – 3 t per charge. Seismic vibrations are one of the harmful manifestations of m
