Abstract:

Research has been conducted relating to the optimization of explosives and initiation systems for a proposed automatic continuous drill-and- blast tunneling system. Experiments concentrated on the development, characterization and selection of explosives which could be automatically injected in bulk form into a borehole and which have optimized safety, initiation, energy and economic characteristics, and the development of reliable, economical, remote initiation systems. The experiments demonstrated that a variety of explosive systems exist whose detailed formulations can be tailored to minimize toxic fumes, optimize safety and initiation characteristics.
