METHOD FOR UNDERGROUND DEVELOPMENT OF THIN, SLOPING AND INCLINED VEINS WITH COMBINED FILLING Russian patent published in 2016 - IPC E21C41/22 E21F15/00 

FIELD: mining.

SUBSTANCE: invention can be used at underground development of thin, sloping and inclined veins. Method consists in preparation and cutting treatment units, sections of blasting wells with formation rock barrier, parallel breakage face, in construction of stowing connection straps along development workings and in filling gaps between adjacent rock shafts hardening stowing. Construction of stowing connection straps and filling of hardening filling of gaps between adjacent rock shafts is performed during development of block-section, with delay from mining face by width of one section with recess cores in rocks below middle stability or, after complete development unit, series throughout height of core extraction unit inclined in rocks average mean stability.

EFFECT: higher safety of mining operations and wider field of use geotechnology with separate excavation of ore and rock.
