Abstract

Internal air leakage of local ventilation fan at individual work. Local ventilation of dead-end mine workings during sinking is carried out by local 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 Qface can be so small that the ventilation will be ineffective even at fan capacity Qfan exceeding several times Qface. With the increase in the length of excavations, the control of air leakage along the length of the pipeline is of paramount importance.
