• Description:
  In blasting, an initiation system transmits energy from the shotfirer's location to the charge in the blasthole. Until recently, the blaster could choose from three basic initiation systems: (1) the total electric system, (2) cap and fuse, and (3) detonating cord systems. A fourth system, which is a variation of system 3, is an in-hole assembly consisting of a blasting cap connected to a low-energy (4 grains/ft) detonating cord downline, which in turn is connected to the detonating cord trunkline. Recent inventions will give the blaster two additional choices. One called hercudet uses an explosive gas mixture inside a network of small plastic tubing. The other, called nonel, consists of a tough plastic tube with a thin coating of explosive (0.1 Grain/ft) on the inside surface. [Description provided by NIOSH]
