EXPLODING DEVICE FOR FORMING HORIZONTAL UNDERGROUND HOLLOWS AND METHOD FOR PERFORMING EXPLODING OPERATIONS WITH USE OF SAID DEVICE Russian patent published in 2005 - IPC

FIELD: mining industry.

SUBSTANCE: device has metallic body with loading chamber in central portion and coaxial to this chamber. Into loading chamber slow detonator and cumulative charge are put. Into each ring-shaped hollow slow detonator, breach charge and isolating pipe for isolating explosion from environment after detonation of breach charges are put. According to method detonator wire, slow detonator and cumulative charge are put in loading chamber made in metallic body of device. Slow detonator, breach charge and isolating pipe are put in each of two ring-shaped hollows, made around loading chamber. Exploding device is lowered into vertical well to productive bed. Slow detonators and breach charges are exploded for putting isolating pipes in contact with wall of vertical well. Cumulative charge is then detonated.

EFFECT: long and concentrated distribution of explosive energy.
