A method for destruction of rocks includes blasthole drilling, placement of non-explosive destructive compositions increasing their volumes at hydration there, with forced effect on rate of a hydration reaction. To the mouth section of the blast-hole packer is installed, and increase of rate of hydration reaction performed through formation of initial pressure of non-explosive destructive composition in the blast-hole in mechanical way, for instance by means of hydraulic prop, or through placement at the bottom section of the hole of non-explosive destructive composition that has higher rate of hydration reaction, and the rate of hydration reaction is increased through addition to non-explosive composition of chemical substances that have exothermal reaction with it, for instance potassium permanganate. The realization of the method for destruction of rocks makes it possible to increase the rate of increase of pressure on the walls of the blast-hole at self-expansion of non-explosive destructive composition in the process of hydration, this increases the rate of destruction of rocks and effectiveness of action of non-explosive destructive compositions. |
