Abstract
Encapsulated shaped charge for efficient initiation of hydrodynamic velocity detonation of explosives column. A water tight capsule with angled sides containing sufficient quantities of explosive and a detonator means where the capsule substantially occupies the cross-section of the bore-hole. The capsule contains up to 30 pounds of explosives. The capsule efficiently and sufficiently initiates a column of explosives whereby the amount of Nitrogen Dioxide is substantially decreased.
Claims31
A shaped charge detonation device with a shaped charge of explosive material used to initiate a column of blasting agent, said shaped charge detonation device comprising:
- a capsule filled with the explosive material, said capsule having a shape to direct an initiation energy towards the column of blasting agent, said capsule shape including a tapered end, a substantially flat end opposite the tapered end and a passage from the flat end to the tapered end through a center of the capsule with a tube located in the passage, said capsule being formed from a plastic material,
- a detonator for initiating the explosive material, and
- a detonation cord to initiate the detonator.
A shaped charge detonation device with a shaped charge of explosive material used to initiate a column of blasting agent, said shaped charge detonation device comprising:
- a capsule filled with the explosive material, said capsule having a shape to direct an initiation energy towards the column of blasting agent, said capsule shape including a tapered end, a substantially flat end opposite the tapered end and a passage from the flat end to the tapered end through a center of the capsule with a tube located in the passage, said capsule being formed from a plastic material,
- a detonator for initiating the explosive material, and
- a detonation cord to initiate the detonator,
- wherein the capsule includes a recess in the tapered end for the detonator.
A shaped charge detonation device with a shaped charge of explosive material used to initiate a column of blasting agent, said shaped charge detonation device comprising:
- a capsule filled with the explosive material, said capsule having a shape to direct an initiation energy towards the column of blasting agent, said capsule shape including a tapered end, a substantially flat end opposite the tapered end and a passage from the flat end to the tapered end through the capsule with a tube located in the passage, said capsule being formed from a plastic material,
- a detonator for initiating the explosive material, and
- a detonation cord to initiate the detonator,
- wherein the capsule includes a recess in the tapered end for the detonator, and
- wherein the plastic material of the capsule above the recess is thinner than other areas of the capsule.
A shaped charge detonation device comprising:
- a shaped charge of an explosive material contained within a capsule which operatively releases an initiation energy upwardly into a column of blasting agent in order to ensure a resultant detonation reaction attains steady state velocity of detonation in the blasting agent column close to the shaped charge device and thereby prevent deflagration of the blasting agent,
- said capsule,
- a detonator for initiating the explosive material, and
- a detonation cord for initiating the detonator,
- wherein the capsule provides a shape of the shaped charge which operatively reduces emissions of Nitrogen Oxides from detonation of the blasting agent column, and
- wherein the capsule has a snap-fit lid for sealing and a tube with open ends through a centerline for a passage for the detonation cord.
