Aw, c'mon, Mac. the method employed in digging up coal is irrelevant. What is relevant is what the coal is used for.
Coal is an essential source for various chemical constituents extracted for other industries as well as used for wasteful burning to provide energy. The latter obviously produces GHG but does anyone know how much GHG the chemical by-product extraction processes produce?
Can the chemical by-products extracted be obtained from other sources?
