Scenario 2 Underground mining below existing open pit. Scenario 3 Open pit mining through existing underground working.The truth of the matter is that more often than not, open pit mining and underground mining go hand-in-hand. When open pit mining, the most geomorphic intrusive mining method, is no longer cost effective, underground mining takes over where possible. However, the damage has been done to the surface of the land.
