METHOD OF MINING OF INCLINED ORE DEPOSITS Russian patent published in 2003 - IPC

FIELD: mining; applicable in underground mining of ore medium deposits. SUBSTANCE: method includes sinking of raises and main haulage drifts in rocks of lying side with drawing holes, ore breaking from drilled workings with broken ore delivery by blast force to drawing holes, drawing and haulage of ore over drifts and block raise. After driving of block and ventilating raises to the dip of ore body, driven on each subhorizon simultaneously with main drifts in ore body are additional scraping drifts which are interconnected by drilled raises. From the latter, ore is broken and hauled over additional scraping drifts to drawing chute, and further over block raise. During second stage, ore is drilled-off from additional scraping drifts. Broken ore is drawn through drawing chute to main scraping drifts and further hauled over block raise. EFFECT: reduced impoverishment of ore with preserved safety in mining. 2 dwg
