Assessment of effective parameters on dilution using approximate reasoning methods in longwall mining method, Iran coal mines [PDF]

arXiv, 2008
Approximately more than 90% of all coal production in Iranian underground mines is derived directly longwall mining method. Out of seam dilution is one of the essential problems in these mines. Therefore the dilution can impose the additional cost of mining and milling.
