Determination of air losses and calculation of depression in parallel workings
Authors:
Abstract
In order to provide cleaning and preparation faces with sufficient amount of air it is necessary to correctly determine air losses both at operating mines and at their design. In many mines of Donbass, as well as in other coal basins of the country, a significant specific weight (often reaching 50-70%) in the general mine underground leakages falls on air losses in parallel workings.
