Anthracite coal, mined from the planet's oldest geological formations, has spent the longest time underground. The coal has been subjected to the most pressure and heat, making it the most compressed and hardest coal available. Hard coal contains greater potential to produce heat energy than softer, geologically "newer" coal.

By the 1990s coal use became the norm. Typically coal preparation involves drying and grinding coal to tiny particles of less than 1mm for injection. The coal particles are separated from released gases in a cyclone. The waste gas, and sometimes natural gas, can be used for drying additional coal, which is generally kept below 6% moisture content.
