Continuous mining is associated with another common method of extracting coal from underground, the "room-and- pillar" method. A continuous mining machine breaks coal from the face of the seam with tungsten bits on a revolving cylinder then moves the coal onto a conveyor belt for transport to the surface.

The U.S. Department of Energy (DOE) Office of Fossil Energy supports activities to advance coal-to-hydrogen technologies, specifically through the process of coal gasification with carbon capture, utilization, and storage. DOE anticipates that coal gasification for hydrogen production with carbon capture, utilization, and storage could be deployed in the mid-term time frame.

The conversion of coal begins in pulverized coal combustion systems, which start the process by steaming coal, which then turns into powder. In its powder form, coal is added to boiler combustion chambers, which heat the substance to high temperatures. This reaction produces hot gases and heat energy, which combine with water to form steam.

Many U.S. coal beds are very near the ground's surface, and about two-thirds of coal production comes from surface mines. Modern mining methods allow us to easily reach most of our coal reserves. Due to growth in surface mining and improved mining technology, the amount of coal produced by one miner in one hour has more than tripled since 1978.

The method used to estimate carbon emissions from energy consumption was revised for the 2016 edition of the Statistical Review. The previous method for calculating CO 2 emissions was constructed by applying a single emission factor to each of oil, gas and coal, as reported in the footnote of the table 'Carbon Dioxide Emissions'.
