The drill and blast method in mining involves drilling holes into rock, filling them with explosives, and initiating controlled detonations. An integral aspect of this process is the strategic use of detonation delay, where intentional pauses between explosive charges in different holes enhance the effectiveness of fragmentation. This technique ensures improved rock breakage, minimised ground vibrations, reduced flyrock, and optimised energy distribution. The calculation of delay times considers
