Abstract

It has been established that ground vibrations generated as a result of detonation of commercial explosives will depend on explosive charge per delay, delay intervals, geology of the transmitting media, geology of the blasting site, direction of initiation and blast design parameters. Keeping all the parameters constant, as stated above a study was designed to assess the effect of total explosive fired in the blasting round on the magnitude of blast vibrations, in three opencast mines. A delay interval of 25 ms was employed to keep the maximum charge per delay constant in all the blasting rounds. The interesting result is that the magnitude of blast vibrations was influenced by the total amount of explosive used in a blasting round at shorter distances, instead of maximum charge per delay. The earlier researcher monitored the vibrations in most of the cases at distances far from the blasting site
