Realistic Coal Seam Generation

[xX_Coal888Min3r_Xx]

A pet peeve of mine is the fact that as a IRL coal miner the coal generation in these survival games is never realistic. Coal forms in wide seams that vary in thickness. The fact of the matter is that coal "ore" doesn't exist IRL. If there was world generation that put Bituminous and Anthracite coal in a seam generation, perhaps even a system for middling shale binders that reduce coal output from the block that you mine. This would be a very cool and appreciated addition. Also It would create the opportunity for specialized coal mines. Perhaps Lignite can still spawn more haphazardly in hilly regions, but it would be very interesting to have the Bituminous and Anthracite coal fields be rare enough, but also large enough, to develop a designated mining outpost for the coal
