Is surface mining is less coast and inexpensive?
Surface mining is MUCH less expensive than underground mining. Usually. In some cases, underground mining is used because the substance being mined is just too deep to have a surface mine. I was just in a silver mine that is more than 5,000 feet deep. If the mine had to remove a mile of rock to get to the silver, it would not be worth mining. In THAT case, underground mining is less costly.

They mine above ground
