Physical basis mechanism of rock failure

This article describes methods that allows on the basis theory breakdown of an arbitrary estimate parameters shock wave on wall borehole of the explosive cavity, with the polytropic compression of real gas. The methods determining parameters of stress waves, based on consideration phase transitions in the process of static stress unload. Estimation effective use emulsion explosives and watergel explosives at mechanism of rock failure.
