METHOD OF DISTANT MINE PLANTING IN MASSIF

摘要

FIELD: mining industry. SUBSTANCE: method includes preliminary making of channel and intruding into the channel of explosive charge in the form of projective with strong metal body. The method is distinguished by provision in massif of channel with diameter equalling 0.70-0.95 projectile caliber and projectile intrusion into the channel at initial velocity of 500-900 m/s. EFFECT: higher efficiency.
