FIELD: shaft cooling. SUBSTANCE: the shaft cooling construction uses large-block concrete panels and thick-walls cooled pipes, whose length equals the shaft height with a combined coolant inlet and outlets, two sliding supports fixing the arrangement of pipes. The distance between the axes of pipes equals 1.8 to 2.2, and the concrete layer thickness equals 2.5 to 3.5 of the cooling pipe outside diameter. EFFECT: enhanced efficiency. |
