FIELD: mining.
SUBSTANCE: method of shaped charge drilling includes creation of a well with the help of cumulative action, in process of which explosive charges are fed by turns into the well and exploded, at the same time explosive charges are arranged with charge hollows. Previously on the axis of the charge hollow with a hollow behind the charge they install either a projectile, or a missile, or a torpedo, containing explosives, then in direction in front of the hollow along the hollow axis they feed a charge with a hollow, and the charge with the hollow is exploded, and then in the same direction they either feed a projectile, or a missile, or a torpedo, and explode it further from the place of explosion of the charge with the hollow, at the same time the projectile, the missile or the torpedo contains an explosive. The device comprises split warheads, and at the same time shaped charges are arranged in head parts of warheads, and in tail parts of warheads there are either projectiles, or missiles or torpedos.
EFFECT: increased speed of drilling.
