Abstract
The explosive preparation of rock for excavation at the open pit is always accompanied by such negative phenomena as the release of dust and gases, the formation of air and seismic waves, as well as the uncontrolled scattering of separate pieces of exploded rock. In this regard, when carrying out mass explosions at an open pit, it is necessary to limit the on above-mentioned negative effects of an explosion in the field area. A new technology of detonation is proposed to reduce the negative impact of an explosion by reducing the limiting pressure of gaseous products of explosives on the wall of the charging cavity. Using the example of the Aramus open pit, the possibility of regulating the degree of rock crushing and reducing the negative impact of the explosion is considered.
