FIELD: mining.
SUBSTANCE: tubing block is exposed over height in two levels. Top level is vent-and-waste floor to release all air from tubing block and to feed stowing mix in breakage heading. Bottom level is haulage level and serves to feed fresh air for mining operations and haulage of all rocks from tubing block to shafts. Spiral descent is made for entire height of tubing block with entries to layer drifts, ore and delivery entries. Divided layer is developed by cul-de-suc miner with pillar width equal to that of cut. Attachment and formation of stowing bulk are made. Breakage cutting is performed by miner transversely to direction of strata and pillars are installed. Heading is vented by local blowers.
EFFECT: higher efficiency and safety.
