METHOD FOR DRILL-HOLE HYDRAULIC MINING OF MINERAL DEPOSITS Russian patent published in 1994 - IPC

Abstract RU 2014456 C1

FIELD: mining industry. SUBSTANCE: a generator of elastic vibrations is placed into vertical drill-holes. Mining is intensified by exciting elastic pulsating pressure waves in drill-hole whose power spectra have rock dilution frequencies. Besides, pulsating pressure waves are excited simultaneously in two drill-holes spaced at a distance defined by a mathematical expression. EFFECT: higher efficiency. 2 cl, 2 dwg
