FIELD: mining industry, particularly to form venting system, which controls thermal mine conditions during combined mining.
SUBSTANCE: method involves forming overburden haulage inclined out of the pit extending across the strike up to interface between exposed and underground mines; extracting mineral from the haulage; constructing venting means and mounting support in approach mine; erecting heat-exchanging mines during opened mining.
EFFECT: elimination of time intervals during venting system construction and mining performing, simplified people evacuation in emergency and possibility to use heat-exchanging mines for other purposes.
