FIELD: mining industry. SUBSTANCE: when developing nose-type folds during opening of seam transportation heading is driven in addition in symmetry relative to wings of nose-type folds. Rings of raise production wells are drilled from transportation heading. Artificial roofing of plastic hardening material is formed in advance with the aid of auxiliary wells drilled from surface. EFFECT: improved efficiency of process. 1 dwg
