FIELD: mining.
SUBSTANCE: method involves performance of uncovering developments of the main and auxiliary shafts, developments of shaft inset, from which the main bottom and upper gangways are led. Crossentry or slope and two passways near them are taken from gangways. Storeyed upper and haulage gangways are located throughout the length of mine section, connected to each other with face entries and mining equipment complexes are mounted in them. Coal is extracted from long faces simultaneously in crossentry and slope parts of panels. Slope part is bottom-up developed. The last mine sections in panels are developed with pillar extraction near the main gangways.
EFFECT: invention allows decreasing coal losses, increasing concentration of mining operations, stabilising the operation of development faces and improving the quality of extracted coal at bulk mining of mined rock.
