OPEN DEVELOPMENT METHOD OF WATER-BEARING MINERAL DEPOSITS

摘要

FIELD: mining.SUBSTANCE: open-pit field in its water-bearing part is developed alternatively from above-water and under-water faces by an excavating machine installed on the pontoon used earlier during development of open-pit field in its non-watered part. Undeveloped pillar of the open-pit field is left in its water-bearing part.EFFECT: increasing the development efficiency of water-bearing mineral deposits without performing any additional operations.2 cl, 6 dwg
