Coal drying at the mine rather than the power plant

When coal drying is done at the mine the coal fines can be gainfully employed to generate steam which in turn can be used to dry the high moisture coal This means the fuel cost for coal drying at the mine becomes practically zero or negligible and eliminates the biggest economic hurdle for coal drying
