Sorry for all the minor edits, I should be using preview more.
Is there a reason "open cast mining" and "underground mining" are in parantheses?
I moved the blasting and prospecting sections to Mining engineering, both because it is correctly titled, and it was created first.
I left this article intact for now.
I also left the first paragraph here, not integrating it with the Mining engineering article at all because they are pretty much the same content.
