Bituminous coal is described as:Diaphaneity (Transparency): OpaqueColour: BlackStreak: BlackCleavage: None ObservedSee PicturesIts texture is smooth, mostly glossy to somewhat dull, a soft coal. Once mined, it can easily break apart.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.
The coal dusts have large surface area thus it can easily absorb the heat and reach its ignition temperature and thus can burn easily... Remember a wood fillings can be easily burned in seconds but a wood block cannot be burnt easily as it takes time to transfer heat to all its body and thus reach the ignition temperature...
The advantage of coal is that it is easily mined. Other then that it runs out fast, it burns to C02, there is very little of it, takes really long time to produce and it is hard to convert to energy.

Coal miners use a pick axe to break up the coal seams and remove the coal from the earth. The pick axe allows them to chip away at the coal and break it into manageable pieces for extraction.
