Effectiveness of measures to reduce mine air leaks

Abstract

In the process of operation of mines there is a need for depression surveys and survey of ventilation, as a result of which are measured: the total flow rate of fans, the amount of air entering the mine, leakage, the amount of air reaching the cleaning and preparation faces, depression of individual jets, sections and the mine as a whole and other ventilation parameters. As a result of the survey should be outlined measures to improve the ventilation of the mine, including reducing air leakage.
