According to the elastic wave theory combined with the propagation law of shock waves in rock or rock-like media. a slotted pipe wall is assumed to be elastic. irrespective of the attenuation process of detonation and shock waves in the coupling medium. The reflection of detonation and shock waves at the slotted pipe and blasthole walls is also assumed to be positive reflections. https://jalyttlers.shop/product-category/rugs/
