Internal air leakages during operation of partial ventilation fans
Authors:
Abstract
Internal air leakage of partial ventilation fan at individual work. Partial ventilation of dead-end mine workings during sinking is carried out by partial ventilation fans and ventilation pipes. Mine pipelines are mostly leaky and leak a significant amount of air at the joints. The amount of air entering the face through the pipeline Qmine; can be so small that the ventilation will be ineffective even at fan capacity Qv, exceeding several times Qmine. With the increase in the length of excavations, the control of air leakage along the length of the pipeline is of paramount importance.
