Abstract
The influence of natural fractures and blocks of different categories and orders on the parameters of explosive fracture of rocks is considered. The results of calculations of the size of fracture zones during explosion in monolithic and fractured rocks, as well as the influence of natural fracturing and the thickness of spalling layers on the granulometric composition in the spalling zone are presented.
