FIELD: mining art; development of rock in underground conditions.
SUBSTANCE: proposed method includes drilling ascent wells, loading these wells, tamping and explosion. Novelty of invention consists in tamping the wells with monolithic rods made from viscous material and provided with taper plugs at the ends which are located between explosive charges and stop of drilling room.
EFFECT: enhanced efficiency; increased useful work of explosion due to increased length of explosion pulse.
