ABSTRACT:
Rock slabs or pieces are broken from larger rocks or from rock formations with reduced cracking of the broken rock slabs or pieces by drilling bore holes along the desired break lines, placing detonating cord into the bore holes, filling the bore holes with a shock transmitting and moderating composition, and detonating the detonation cord. The shock transmitting and moderating composition is preferably a gel with shock absorbing material such as microspheres or micro gas bubbles suspended therein. Openings in rock can also be formed by drilling at least one bore hole within the desired opening and drilling a plurality of bore holes along the desired periphery of the desired opening. Explosives within the at least one bore hole within the desired opening is detonated to break rock within the opening and detonating cord in the bore holes along the desired periphery of the desired opening which holes are filled with a shock transmitting and moderating composition is detonated to break the rock inwardly of the desired periphery while leaving stable the rock outwardly of the periphery.
