Theory and Practice of Air Deck Blasting in Mines

· The mechanism by which the explosive energy is transferred to the surrounding rock mass is changed in air deck blasting It allows the explosive energy to act repeatedly in pulses on the surrounding rock mass rather than instantly as in the case of concentrated charge blasting The air deck acts as a regulator which first stores energy and then releases it in separate pulses
