Coal is also used in the steel manufacturing process, which utilizes coke, a by-product of burning coal. Some structures and industrial installations still use coal for heating the actual structure, though these are becoming quite rare. Most modern industrial uses for coal, outside of electricity production, involve large coal-fired furnaces.

Mining of coal is still a problem from an aesthetic point of view. Seams near the surface are often strip mined and backfilled, leaving temporary scars on the landscape. Deep coal seams have to be mined through tunnels, which often collapse, catch fire, or explode as a result of ignition of coal dust or methane released from the coal.
