Abstract
Blasting operations for mining frequently involve a large number of detonators for a single blasting event. An important step in the execution of a blast is to perform a roll-call to check that all detonator assemblies placed at the blast site are in communication with a blasting machine, and forming operative components of the blasting apparatus. Disclosed herein are blasting apparatuses and methods of blasting that streamline this roll-call step, thereby reducing time consumed in the blasting process.
