If the smoke of the heat of the boron is required to be lowered below the surface of the earth, then the base of the chimney and Borov are placed in the reinforced concrete goglell, surrounded outside with a layer of sand mixed with peat or moss, while the gallery should be launched into a layer of permafrost at least 1.5 — 2 m. In this case, both the smoke pipe and the borov should be based on wooden piles. The specified design gives strings during distortions due to the possible uneven precipitation of their foundation when thawing eternal permafrost.
