Vibration and air blast noise from blasting were evaluated during a research program sponsored by the Bureau of Mines. Blast variables were studied using small-scale model tests to evaluate specific variables as well as interactive effects, followed by experiments with production blasts at the surface coal mines. Experimental data showed that the primary variables affecting the ground vibration amplitude are the charge weight per delay and the length of the delay interval. Blast variables with a significant affect on the overpressure amplitude include the charge weight per delay, the length of the delay, burden and spacing, stemming amount and type, direction of initiation, charge depth, and amount of detonating cord and cover.
