From the indigenous

To serve 12 layers in each of the four air heaters in the shift, 7-8 utility workers were enough, instead of 23-30 serving earlier. The number of auxiliary workers on the laying of fireproof houses and air heaters decreased by 328 people. The masonry of fireproofs Domna organized in three tiers. On the first tier — bream, mountains, a buffet zone, pesners — in each shift, 18 stoves were busy with three -shift round -the -clock work. On the second tier — from the motor ring, open, the middle and upper part of the mine, including the armor part — from the indigenous forests on the masonry of these structural elements, 24 stoves per shift were occupied. On the third tier — the cone of the junker, gas outlets and candles — the masonry was also organized around the clock, in three shifts.
