I don't know of how any that are restricted. Or rather I don't know of any that aren't. To my knowledge they restrict them all because Quarries and Mines are dangerous to people. At night it's especially hard to get around because it's dark and you might fall. That doesn't stop people though. You always hear stories about how they dump bodies into them. There's a little gravel quarry about 2.5 miles up from where I live. It's closed at night. During the day they don't like people around there unless they have business. To much running machinery that can harm people.
