FIELD: mining industry. ^ SUBSTANCE: method includes driving main ventilation, level backup and ventilation drifts, connecting shafts and extractive block is extracted fully with following backfill. Prior to start of extraction of resources of extractive blocks at cleaning portion closed space is formed by mounting gate and isolating walls, wherein air is forced via ventilation pipeline from high-pressure ventilator. Relation of shaft pressure of air pressure Ps to air pressure Pp at processed portion during process of extraction of extractive block is set and maintained by inequality 1<Pp/Ps<=3. ^ EFFECT: higher safety of processing of fire-threatening beds to decreased possibility of coal self-ignition. ^ 1 dwg |
