Abstract: Effective, high-quality and steady ventilation of mine workings is one of the main factors that determine safe working conditions in an underground mine. The Juliet deposit is characterized with an irregular shape and varying dips and strikes. In some cases, it consists of isolated and mutually remote deposits with different mining and geological characteristics. These features of the deposit dictate the use of complex schemes for the development and mining of the deep-lying layers, which results in formation of a very extensive and branched network of underground workings. The specific features in the development of the Juliet deposit include the fact that a large number of mining blocks are in operation at the same time, and extraction of these block can be carried out using different mining systems. Intensive removal of dust and gases can be ensured only when a sufficiently large amount of air is supplied to the mine and the individual working faces. In order to overcome the overall air drag in the mine, it is necessary to use high-performance and high-pressure fans that would consume enormous power.

Keywords: ventilation network, ventilation pattern inside the mine working, fan, ventilation of mine workings, ventilation pattern, return ventilation air
