Coal dust is a finepowdered form of coal which is created by the crushing, grinding, or pulverization of coal rock. Because of the brittle nature of coal, coal dust can be created by mining, transporting, or mechanically handling it.. Grinding or pulverizing coal to a dust form before combusting it improves the speed and efficiency of burning, which makes the coal easier to handle.

The Powder River Basin coalbed methane boom in the early 2000s stirred controversies over land rights, mineral rights, environmental stewardship, the disposal of water and—at every turn—politics. Now, few of the 29,000 wells drilled produce much gas and around 3,000 wells are abandoned and left to the state to clean up.

Start adding coal. This raises the 'heat' indicator on the right. If it is below the green region, add more coal. If it is above, do not add coal until it gets lower. If the heat reading reaches the dark orange portion, you have spoiled your compound and must start again; although the coal is wasted, it can be redone with the same barrel of tar.

The coal is ground into a fine powder. This makes it easier to ignite and burn in the boiler. How coal is pulverized? Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or "races." The raw coal is then fed into the pulverizer along with air heated to about 650 °F (340 °C) from the boiler.
