The grindability of coal is important for entrained-flow gasifiers, which require pulverized coal for dry feeding systems or coal with a wide range of particle size distribution for slurry feeding systems. Because grinding is an inefficient process, choosing coals that are easier to grind can increase the overall efficiency of the process.

When coal is formed, large quantities of gas are stored within it. The gas is held in place by water pressure. To extract it, wells are drilled through the coal seams, reducing water pressure and releasing natural gas from the coal. The gas and water are separated, and the gas is piped to compression plants for transportation.
