METHOD OF BORE-HOLE HYDRAULIC RECOVERY OF MINERALS |
摘要 |
FIELD: mining industry. SUBSTANCE: according to method following operations are performed: opening of productive formation by means of producing well and auxiliary wells, creation of artificial roof at boundary of covering rock and productive formation in the form of arch of natural equilibrium with additional anchoring of roof in covering rock. Hydraulic recovery operations are carried out under natural roof in winning chamber. Bottom of this chamber is made in the form of cone turned upside down.
