摘要

Method for preparation and mining of extraction districts according to which at preparation of each district in extraction panel ventilation drift is penetrated with cross section minimal needed or even smaller compared to complex-mechanized development of the district, and at development ventilation drift is increased in width near the face, all the volume of rocks from increase of width that is determined by formula is transported to connection of face and drift with laying there in worked out space of face as a rock pack, and in ceiling and gateside that is increased in width one arranges an additional support-anchor fixation.
