FIELD: mining.
SUBSTANCE: method of mining of mine sections involves main workings, drifting of two belt entries and airways, air conduit, face entry and installation of mining equipment in it, coal extraction from longwall face and turning of longwall bottomhole to 180°. The chambers are developed up to bypass working from the side of upper and lower airways between bypass working and completely near air conduit.
EFFECT: time decrease for reinstallation of mechanical complex, decrease of coal losses and output increase.
