Underground mining generally results in relatively small waste rock disposal areas ranging from a few acres in size to tens of acres (0.1 km2). These areas are typically located near the openings of the underground workings. Open pit mining disturbs larger areas than underground mining, and thus has larger visual and physical impacts.
