Abstract : Much theoretical and experimental material on the underground explosion in sandy ground has been recently published. Works give experimental values for the mass velocities of soil during the explosion of PETN and 50/50 trotyl and hexogen charges and with an electric fusing. This article examines the effect of air-filled cavities surrounding the charge upon the mass velocity of soil particles in the compression wave and upon the parameters of craters during an ejection explosion.
