Not sure if coal meets the criteria folks are looking for, but Bluegrass Fish and Wildlife area is near where I grew up. My father worked most of his career there, mining the coal and doing the reclaim work. I'm not aware of any major environmental issues to the local area.

It is a different quality than some other nearby lands that were strip mined much earlier and never reclaimed. I grew up hunting on some of those places and looking back am very grateful for them. They were the only close public accessible lands.
Having grown up a little bit north from you I also have spent many hours on reclaimed mine ground. There is definitely a distinction from the old ground to the freshly reclaimed areas. I have seen seeps from mining where the ground is blood red from the iron and lakes that are green from sulfur. Near my parents property a neighbor lost a corner of their house to a sinkhole. Another neighbor couldn't get water from a well due to a mineshaft. On the other side of the coin I've seen areas where animals and crops flourish. Heck, in a few areas they are actually mining over old ground that was mined once before. I know Peabody will leave those lands better than what they were when they moved in. Like Thedudeabides said when done correctly by the operator it can be just as good as it was before.
