摘要

FIELD: mining.;SUBSTANCE: method involves drilling of beds with longitudinal working trench along the strike and their development, drilling and preparation of beds with underground mine openings and their development, and reclamation of drilled mine openings. Drilling is performed by means of trench to the outlets of above lying beds and outlet of thick bed for deposits along the strike to the boundary of mining allotment with advance of trench to develop thick bed. After advanced underground development of above lying beds to the depth of its effective development with open method, opening of beds in the edge of trench is performed by drift ways from the worked-out area of the cut and with inclined shaft from the surface. Above lying and thick beds below the trench bottom are drilled with ventilation and conveyor crosscuts, and vertical shafts driven to the lowest point of series of beds.;EFFECT: invention allows increasing the completeness of excavation of mineral product and reducing the scope of stripping works, environmental damage and losses of resources.;2 cl, 3 dwg
