because it has minerals
Yes. Coal is a common source of the heat needed to make cement.
High grade coal can be treated in a special furnace to produce coke, which is needed to produce steel. Coal is a natural form of Carbon. Most coal goes straight to power generators to make electricity.
Coke, often made from bituminous coal refuse, is formed from burning off volatile components. That leaves solid fuel that burns longer and hotter than coal.Anthracite (hard) coal burns the hottest and cleanest, but this coal is in shorter supply because it takes longest to form.Bituminous (soft) coal has variable amounts of volatile components (low, medium, high) and burns 'dirty'. But it provides long, fairly even burning.Factories could and did use bituminous coal. But burning coal refuse to make coal rescued the coal while getting rid of gunk and impurities. Steel mills, which needed high, even, and longer-lasting burns for steel production, required coke.For coal companies, mining and processing of "coal and coke" increased revenues from all grades of coal. At one point, Fayette County and Washington County both in SW Pennsylvania were dotted with "beehive" coke ovens used to burn off coal's impurities.

The Coal Handling Plant is needed in the coal handling process.

The miners would dig a hole and put any mining tools they needed to get the coal out. but no not all the coal was removed.

Oxygen.
How many people are needed to work at a coal power plant depends on the size and age of the plant, among other things.
Raw Materials were what the peoples depended on. To make product, they needed cotton/coal/etc, and they needed to make product to sell and trade. Raw Materials were a basic need.
