FIELD: mining industry.
SUBSTANCE: invention relates to mining industry and can be used in extraction and processing of ore raw materials of steeply dipping ore deposits by underground method. Method of development of steeply falling ore deposits with longlines includes working out lower tier from below upwards with systems with embedding of worked-out area, upper tier downwards by systems with ore caving and enclosing rocks, with enrichment of ore on underground concentration plant and production of concentrate, while mine refuses are used as packing material. For bypass of all mined ore to underground concentration plant, gravity is used. Complex is located at maximum approach to ore body. Mine refuses are used to embed worked-out chambers only in lower tier.
EFFECT: invention makes it possible to increase safety and efficiency of extraction technology and processing of ore raw materials.
