The mine run coal is crushed to a size for coking coal requirements. The entire production is treated over a coal jig which removes as waste primarily the coarse refuse. The coarse clean coal passes over the jig along with the fines and is elevated to a wedge bar stationary screen with 1 millimeter openings for dewatering.
The state of the mine ventilation needs to be monitored to ensure that the quantity of air is maintained consistently and that emitted gas levels are maintained below safe threshold levels. Monitoring is done both manually and by the use of continuously operating monitors that may indicate remotely often to the surface. Ventilation Coal Transport
