Designing blast patterns by calculation of fracture zones and ore zoning by physical and mechanical properties

Influence of the nature of the outflow of explosion products from blast holes and boreholes on the efficiency of rock destruction

“…-maximum release of potential energy [3,4,5], prevention of energy loss during detonation and its completeness; -higher initial gas pressure, as well as bigger effective length of the blast wave, which determines the value of the line of least resistance (LLR) according to the theory of rock destruction by a reflected wave [6]; -greater piston action of the explosion products (EP) on the walls of the explosive cavity and length of the radial cracks formed during the explosion.…”
