The article evaluates the effectiveness of the use of technological shock wave cutting of rocks. A significant reduction in the consumption of explosives and an increase in efficiency in shock-wave cutting are shown. Tasks have been solved in the interests of rescue operations in emergency situations. Characteristics of the degrees of destruction, methods and given. An analysis of the development of critical situations with the mortality of victims is given. Use of bilinear charges that realize Mach wave cutting (extreme modes of shock wave interference). Shock wave cutting of rock is an innovative technology for the mining industry, blasting operations during the demolition of structures and rescue operations in case of debris of rocks, buildings and structures.
