Bituminous coal was known about and mined as far back as Native American Indians. Bituminous Coal exists in the geological area known as The Pittsburgh Coal Seam-- an area extending from Western Pennsylvania, Western West Virginia, Ohio, Kentucky, and Indiana. Though mined since the days of Native American Indians, and heavily mined since 1800, it is estimated there is still enough coal in this large seam to last millions of years. Two differences about bituminous coal are:
The main types of coal are anthracite, bituminous, and lignite. Anthracite is the highest rank of coal and has high carbon content, making it the cleanest burning coal. Bituminous coal has a lower carbon content and is commonly used for electricity generation. Lignite is the lowest rank of coal, with the highest moisture content and lowest carbon content, making it less energy-dense than anthracite and bituminous coal.

No it is not but bituminous coal is
Anthracite.
One difference is their carbon content: peat and lignite have lower carbon content compared to bituminous and anthracite coal. Another difference is their formation process: peat is not fully coal yet, as it is the earliest stage of coal formation, while anthracite coal is the highest grade and the result of further coalification processes.
Anthracite is harder than bituminous coal. Anthracite has a higher carbon content and lower moisture content, making it a more dense and harder coal type.
Other names for coal include anthracite, bituminous coal, lignite, and thermal coal.
yes, there are: Anthracite Bituminous sub-bituminous lignite
The protolith of schist is typically shale or slate, which undergoes metamorphism to form schist. The protolith of anthracite coal is primarily bituminous coal, which is subjected to higher temperature and pressure conditions during metamorphism to convert into anthracite coal.
bituminous is less hard,and its dull.whereas anthracite is very hard.
