A Fundamental Study on the Prevention of Occurrence of Channel Effect

摘要：

The precursor air shock wave (PAS) in air channel, which is propagating ahead of the detonation front, precompresses and desensitizes the unreacted explosive charges. This dead-pressing phenomenon is commonly known as the channel effect. To investigate the prevention of occurrence of channel effect in emulsion explosives in the case of smooth blasting, experimental works have been carried out in laboratory.
