"In an attempt to determine the influence of charge length upon cratering, a series of small scale model blasting experiments were conducted in Plexiglas, Hydrostone, mortar and dolomite, using mild detonating fuse as the explosive charge. Single hole blasts were simulated, with the blasthole being drilled normal to one free face and parallel to a second. The resultant craters were photographed and closely studied. Particular attention was paid to effects of variation of charge length and burden upon cratering.
The investigation showed the importance of radial fracturing and the dominance of gas pressure in explosive crater formation from elongated cylindrical charges. It also demonstrated that charge length and placement geometry exert a major control upon cratering and fragmentation"--Abstract, page ii.
