FIELD: mining. SUBSTANCE: method includes segregating excavating section into breasts oriented along slope, providing undercutting space and ore receiving workings of layer-by-layer ore breaking by fan-shaped well sets in lower part of the breast. The well sets are drilled in ore massif from riser. Ore is delivered by explosive force to ore receiving workings. Magnetic field is formed in worked off space of breast adjacent to roof. Vector of magnetic induction is arranged horizontally and in the direction of ore delivery. Besides magnetic field is formed for the time of explosion in the breast. Electric magnets are used to form magnetic fields. The magnets are placed in joint points of horizontal connectors and worked off breast space. In so doing connectors are driven from subsidiary crosscuts adjoining ore receiving workings of the breasts. EFFECT: higher productivity. 3 cl, 2 dwg
