I think this diagram should help, it doesn't have all the stages you list but anthracite coal is very dense and is the last stage of coal formation

Lignite is formed slightly after peat

Answer 10

Drilling I would assume would not be labeled as the first step of refining because you are simply just moving it from one place to another.

They heat it distil it into its many parts, then they do a thing called thermal cracking which essentially changes large molecules that aren't of value into the smaller desired molecules.

Cooling is probably the final step

You should check your notes though, I wish I had mine on me I have a really good chapter from a previous course on this material.
