FIELD: mining.
SUBSTANCE: method includes development of beds with longwalls along the strike using mechanised complexes. For this purpose during development of each underlying bed a longwall is arranged so that the remaining coal sight pillars near ventilation and conveyor drifts of the overlying bed are above the middle part of the extraction column, and extraction of coal beds is carried out in descending order.
EFFECT: higher safety of development of contiguous beds and lower labour inputs for roof management.
