Summary
"Blasting phenomena are affected by many factors. Previous investigators have studied many of these factors, however, the influence of charge length and explosive detonation velocity have apparently not been thoroughly examined. It was found by this investigation that the detonation pressure of a commercial explosive is closely controlled by the detonation velocity. The detonation velocity, in turn, will largely determine the necessary blast geometry that can be successfully employed. Relationships were derived between the detonation velocity, in relation to the rock energy propagation velocity, and blast geometry for both bottom and collar primed blasts. The resultant force magnitude and direction at a point in the medium was found to be influenced by the charge length and the velocity ratio. A graphical analysis of the forces in the medium indicated that the direction of the resultant forces along the reflected pulse front is not perpendicular to this wave front. Observed blasting phenomena appear to substantiate the theoretical investigation "--Abstract, page i
