METHOD TO MINE INCLINED ORE DEPOSITS Russian patent published in 2012 - IPC E21C41/22 

FIELD: mining.

SUBSTANCE: in process of ore deposits mining at first driving is carried out in a foot wall of a block or a ventilating risers, scraping drifts. In an ore body there are additional scraping drifts, which are knocked together with drilling risers. Then drilling risers are cut into access chambers by means of ore cutting and scraping to ore chutes, cutting of ore chutes into outlet craters and excavation of ore massif above scraping drifts. Afterwards driving of horizontal ore mines is started, which cut drilling risers with access chambers, and a part of ore massif is mined with cutting of a drill riser with an access chamber with blasting delivery of ore into access chambers jointly with extraction of panel reserves. Prior to extraction of ore massif above additional scraping drifts the worked space is filled in an above panel with injection of a binding material of a lower part of a filled massif.

EFFECT: prevention of damage and degradation of earth surface above mining works with preservation of minimum ore losses.
