An explosive device (10) comprising: and explosive charge body (12) including an explosive charge and detonator (21); a housing (22) attached to the explosive charge body (12); and a length of electrical or non-electrical non-pyrotechnic firing line (26) having a first (28) and second end (32) the m

An explosive device (10) comprising: and explosive charge body (12) including an explosive charge and detonator (21); a housing (22) attached to the explosive charge body (12); and a length of electrical or non-electrical non-pyrotechnic firing line (26) having a first (28) and second end (32) the majority of which is stored within the housing so as to permit progressive removal from the housing on pulling the first end (28) thereof, and which is attached at the second end (32) to the detonator (21). The explosive device (10) can be used in a versatile manner for avalanche control, can allow a degree of positioning after initial deployment and provide safe operation yet is easily handleable, readily deployed and compact, and negates the hazards associated with the use of pyrotechnic delay fuze.

Apparatus according to claim 17 wherein the control unit includes a bar code scanner for obtaining identity data from a readable bar code. 19. Apparatus according to claim 17 which includes means for interrogating a passive transponder which contains the identity number of a detonator and which is carried by or fixed to the detonator. 20. A control unit according to claim 15 wherein the stored time intervals are adjustable to correspond to the time delay between detonators of adjacent blast holes or to correspond to the time delay between adjacent branch lines.
