Abstract
To regulate the impact of explosion in the directional destruction of rocks, it is necessary to use industrial explosives (IE) with a sufficiently wide range of energy, technological and physical-mechanical properties. In some cases, it is even necessary to reduce the volumetric energy density and create controlled systems for energy transfer and extraction. When developing the explosives for the mining industry it should be taken into account that the efficiency of the use of explosives is determined not only by the degree of useful use of the potential energy of the charge, but also by the possibility to control the mechanism of destruction of rocks. The creation of methods of controlling the explosion energy is based on a qualitative change in the mechanism of its action by introducing additives to the PVB composition, improving the technology of preparation, modifying the surface of the energy-intensive metal combustibles.
