METHOD OF MINING STEEPLY DIPPING ORE BODIES AND METHODS OF MINING, PROCESSING AND CONCENTRATION OF COPPER, AND/OR COPPER-ZINC, AND/OR ZINC, AND/OR SULFUR ORES WITH POSSIBLE CONTENT OF GOLD, SILVER AND OTHER PRECIOUS AND RARE-EARTH ELEMENTS FROM STEEPLY DIPPING ORE BODIES

摘要

FIELD: mining industry; underground mineral mining, particular, of complex ores. SUBSTANCE: thickness of deposit and volume occurrence of ore bodies are determined by acoustic sounding and measurement of velocity of propagation of longitudinal waves by apparatuses of pulsed acoustic logging. Levels are divided into sublevels. First, drilled and broken onto slot is lower sublevel of upper level with drawing of broken ore on its haulage horizon. Then, drilled and broken is lower sublevel of lower level with formation of ore pillar at hanging wall and drawing of broken ore. Further on, drilled and broken is upper sublevel of lower level with shrinkage of broken ore for the period of drilling and blasting of upper sublevels of upper level; and drawing of broken ore onto haulage ways of both levels, with bypassing of a part of broken ore of upper level to gob of lower level, is effected after blasting of upper sublevels of upper level, and gob filling is carried out after complete drawing off of broken rock. EFFECT: higher efficiency. 153 cl
