BlastPED System
The BlastPED is a remote 'radio' based blast initiation system, i.e. a remote firing unit. BlastPED was developed to provide a safe, remote blast initiation system for mines by eliminating the high cost of installing and maintaining large firing cable networks, and hence reduce the safety concerns (e.g. induction) with these cable based systems.
Underground Mines
BlastPED PED Version, this system uses the PED Transmission System to communicate with remotely installed receiver/exploders to remotely initiate electric detonators (blasting caps). The system is one way, i.e. remote unit is a receiver only, as the close proximity of this receiver/exploder to electric detonators precludes the use of a transmitting radio for safety reasons.

BlastPED LF Version use's a mine's leaky feeder radio system to communicate with remotely installed receiver/exploders to remotely initiate electric detonators (blasting caps). Again, the system is one way, i.e. remote unit is a receiver only, as the close proximity of this receiver/exploder to electric detonators precludes the use of a transmitting radio for safety reasons.

Open Cut Surface Mines and Quarries
The BlastPED EXEL (also known as BlastPED ST) version was developed for use in surface applications and uses more typical surface radio systems to communicate between a Master Control Unit and a Remote Receiver/Exploder. A key difference to the other two types of BlastPED is this version initiates signal tube (shock tube) directly, rather than initiating an electric detonator. The elimination of electric detonators enables this unit to be two way (i.e. the remote unit can provide feed back on its status), since a transmitter can be used within close proximity to the signal tube.
