摘要：
A dead-pressing phenomenon by the precursor air shock wave (PAS) going in an air channel, is commonly known as the channel effect. We have been investigated the mechanism of the channel effect in emulsion explosives in the case of smooth blasting, some experimental work has been carried out in laboratory. Hence, it is concluded that decreasing PAS velocity would be effective for the prevention of occurrence of channel effect. In this study, the obstacles in an air channel were applied to inhibit the PAS progression. Some experimental works have been made to investigate the influence of obstacles. It is found that an insertion of obstacles into an air channel is one of the effective methods for the inhibition of the PAS progression.
