Quizplus · Accepted Answer

Subsurface mining refers to the extraction of minerals and ores below the Earth's surface. Room-and-pillar mining is a method of subsurface mining that involves creating a network of rooms and tunnels in the rock, leaving pillars of untouched material to support the roof of the mine. Strip mining, contour mining, and mountaintop removal are all forms of surface mining, where minerals or ores are extracted from the Earth's surface.
