MECHANISMS OF DESTRUCTION OF ROCKS UNDER DRILLING

Efficiency of drilling remains at catastrophic deterioration of arms roller bits. This phenomenon is not entered in existing theories of destruction which reject possibility of formation of the main crack in parallel a semispace plane. Presumably it is formed at high-speed unloading of the rock load...
