DEVELOPMENT METHOD OF THIN STEEP FIELDS OF ROCK TYPE Russian patent published in 2010 - IPC E21C41/26 

FIELD: mining.

SUBSTANCE: invention can be used during development of mineral deposits of rock type, which are represented with thin flat mineral bodies, of steep and semi-steep fall, for example with ore veins and lenses. Development method of minefield is performed without people's presence in automated mode, from day surface with minimum number of daylighting works. Mineral bodies are divided into blocks as per their spread with their subsequent processing with mobile bottomhole technical complex by means of which drilling-and-blasting destruction of rocks is performed under local shelter. Conditioned mineral mass is removed and loaded with the excavation device to mineral treatment unit by means of which conditioned mineral mass is prepared for processing and enrichment in the dressing unit. Concentrate and mineral waste is unloaded in lifting devices to the surface, and non-conditioned mineral mass and processes waste of conditioned mineral mass is moved to the chosen area.

EFFECT: increasing development efficiency of solid mineral deposit mines of rock type.
