Abstract
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.
Claims21
An explosive device comprising:
- an explosive charge body including an explosive charge and a detonator;
- a housing;
- and a length of non-pyrotechnic firing line having a first end and a second end, one end being operatively connected to the detonator, the majority of which line is stored within the housing so as to permit progressive removal from the housing on pulling one of the ends thereof;
- and in which movement of the no-pyrotechnic firing line is restrained so as to prevent the one end of the non-pyrotechnic firing line being pulled away from and operatively disconnected from the detonator when the non-pyrotechnic firing line is pulled from the housing.
A method of disturbing a snow or ice formation using an explosive device comprising an explosive charge body including an explosive charge and a detonator;
- a housing;
- and a length of non-pyrotechnic firing line having a first end and a second end, one end being operatively connected to the detonator, the majority of which line is stored within the housing so as to permit progressive removal from the housing on pulling one of the ends thereof;
- and in which movement of the non-pyrotechnic firing line is restrained so as to prevent the one end of the non-pyrotechnic firing line being pulled away from and operatively disconnected from the detonator when the non-pyrotechnic firing line is pulled from the housing, said method comprising deploying the explosive charge body at or near a desired location with the non-pyrotechnic firing line extending from the explosive charge to an initiation site and then detonating the explosive charge.
