мере отработки одного выемочного столба в коивейерной выработке последнего вслед за проходом очистного забо размещают два р да пне&мобаллонов,.и после отработки этого столба fl стабилизации смещени горных пород извлекают один р д пневмобаллонов , примыкающих к массиву угл смежного выемочного столба, и по .мере отработки смежного столба вслед за проходом его очистного забо из.влекают втopo р д пневмобаллонов из указанной выработки и погашают ее.As one mining column is mined, two rows of amphibian and mobile bulbs are placed after the passage of a clearing slab. to the extent of working out of the adjacent pillar, following the passage of its clearing slab, draws, in the opposite direction, a number of air bellows from the indicated output and extinguishes it.
