Static pressure and efficiency of mine suction fan

Abstract

Characteristics of fans are widely used in the design and operation of ventilation systems of mines and mines. Different interpretations of certain aspects of this issue have not been given much importance until now. However, now, during the transition of industrial enterprises to new principles of economic management and economic incentives, engineers have to find reserves for saving material resources and reducing production costs. At the enterprises more and more importance is attached to the issues of testing of mine fans, at the same time, and there are contradictions in the theory and interpretation of certain issues related to the evaluation of the economic efficiency of mine suction fans of main ventilation.
