Open Pit Mining Used to get stuff that’s still close to the surface, but may reach deeper into Earth 1. Overburden removed 2. Holes are drilled 10 -15 meters deep and filled with explosives. Rocks blown up. 3. Ore loaded into huge trucks and processed.

Underground Mining Used to find ores deep inside the Earth. 1. Miners take an elevator down to the working area. 2. Holes are drilled in the rock, filled with explosives 3. Rock is blasted apart. 4. After blast, area is inspected, and weak parts are supported. 5. Rock is brought to an underground crusher, which separates ore, then lifted up to surface.

Mining towns depend on mines for existence When a mine closes, the effect on jobs can be terrible. Often, entire towns shut down, because the mine that supported the economy shut down.
