The analysis of the underground coal gasification in experimental equipment
AbstractThis paper describes an experiment of underground coal gasification in experimental equipment. The experiment was done within the range of the project APVV-0582-06, in May 2010. During the period of 63 h there was gasified amount of 214 kg of coal in experimental gasifier with average rate of 3.4 kg/h.

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