FIELD: mining industry.
SUBSTANCE: method includes upward excavation by horizontal layers, cutting of ore mainly by horizontal blast-holes, distribution of cut ore and filling of excavated space by non-ore filling of empty rock, and excavation of next shafts in current layer is performed from filling surface. With ore cutting in excavated layer partial distribution of it is performed. Remaining ore is stored within the chamber until the layer is fully excavated and chamber is filled. After that ore is distributed and concurrently chamber is filled by non-ore filling, from surface of which next layer is excavated.
EFFECT: lower costs of extraction and processing of ore due to better use of equipment, lower losses of cut ore and lesser pollution of it.
