7.2.1: Open Pit Mining ABC 123: Testing Site / Course

7.2.1: Open Pit Mining. Open pit mining almost always applies to non-coal materials, mostly metal and aggregate mining. However, near-surface steeply dipping coal seams are extracted using open pit mining. Reclamation, i.e., returning the land to an acceptable standard of productive use of the open pit mine is deferred until the mine closes.
