Planning for Reliable Coal Quality Delivery Considering Geological .Jan 9, 2015 . The aim of coal quality control in coal mines is to supply power plants daily with extracted raw material within certain coal quality constraints. On the example of a selected part of a lignite deposit, the problem of quality control for the run-of-mine lignite stream is discussed. The main goal is to understand.quality control coal mining,coal quality control - Energy AssociatesSo while coal quality control is an issue of importance, its means and methodology cannot be separated from its utilization. Combustion technology and fuel quality are coalescent issues. Resource Management. Coal quality control begins at the mine. The mining engineer is responsible for developing the mining plan.
