本文阐述了矿井外部漏风对其能量损耗的关系和矿井漏风率与漏风风阻与矿井综合风阻的关系。同时,并用某矿实例说明由于外部漏风而引起的能量损耗情况。因此,严格控制矿井外部漏风,在安全生产及经济方面均有重要意义。 This paper expounds the relationship between air leakage outside the mine and its energy consumption and the relationship between the air leakage rate of the mine and the air leakage resistance of the mine and the comprehensive wind resistance of the mine. At the same time, an example of a mine is used to illustrate the energy loss caused by external air leakage. Therefore, strict control of air leakage outside the mine is of great significance in terms of safety in production and economy.
