Mar 15, 2019· Sub-bituminous coal is considered black coal, even though its appearance varies from bright black to dull dark brown. Its consistency ranges from hard and strong to soft and brittle due to its intermediate stage—between bituminous and brown coal (lignite). The coal is widely used for generating steam power and industrial purposes.
