- Abstract
The estimation of the energy efficiency of selecting the optimum ventilation conditions of mine workings with variable air flow rate during the winter period was performed. As an efficiency criterion the degree of energy costs reduction when facility ventilating with variable and constant air flow was used. In a specific example it was shown that a simple change in the air volume during the winter period allows you to halve the energy costs required to maintain the frozen state of the rock masses and ensure the stability of the mine workings of the underground facilities.
