Study on Coupled Medium effects of Complex Slotted Charge Blasting

Abstract

Based on the theory of complex slotted charge water, air coupling medium directional fracture controlled blasting analysis and simulation test of similar, draw the complex slotted charge water coupling charge directional fracture controlled blasting effect is better than that of the air coupling blasting; peak pressure than the air coupled charge under the conditions of quicker acting time, effect of higher value, longer duration; water coupling blasting conditions, unit speed peak value than air coupled charge under the conditions of higher.
