Chebenko Y. Control methods development for the rock crushing by means of specific explosive energy management

Object - the processes of destruction of solid media under dynamic loads; the purpose - development of methods for control of the specific energy of the explosion, that is transmitted to array of rocks, in order to reduce the dynamic effect of the charges of high-brisant explosives on contact "charge of explosion-rocks"; innovation - there was experimentally established that at constant specific consumption of explosives and destroying volume, the increase in contact area of the explosive with the environment by reducing the diameter of the explosive cavity leads to an increase in the intensity of the explosive fragmentation of the environment and increase of hidh-crushed fractions, and the results - the first time, found that while reducing the area of direct contact with the explosive rock there is a change in specific energy of the explosion, transferred to the breed, and decreases the volume of high-crushed fractions; industry - mining.
