Abstract
A system for transferring bulk explosive materials comprises at least one bulk explosive material storage tank and a transfer hose connected to this tank. The hose is used to fill a receptacle, typically a borehole in a mine, with explosive material, at least in part. A detonation arrestor device comprises a central channel in the hose adapted to have the explosive materials pass along its outside and fumes to pass along its inside in the event of an unintentional explosion.
