A development program was conducted to provide special equipment for use in a planned rapid drilling, lightweight, high capacity, explosive drilling system. Development services were provided for a unique multi-jet, all plastic, shaped charge capsule used as the drilling tool, and an automatic feeder mechanism to feed the capsules to the borehole. This feeder equipment was adapted to a small commercial drilling unit to create an explosive drilling capability. Safety, capsule producibility, and explosive loading of the capsule were prime considerations during design and development.
