The Bingham Canyon copper mine in Utah is the world's largest human-made excavation. Like most large open-pit mines, Bingham's walls are terraced to reduce landslide risk and enable heavy equipment to reach mineral-bearing rock. Vertical faces are called "batters," horizontal surfaces are "benches."

Evident in the distribution of open-pit and underground mines, excavation type, and to a lesser extent mine depth and fugitive methane, drives variations in emissions intensity for metallurgical coal operations (Exhibit 2). When coal is mined, the surrounding methane that developed as the coal formed over time is released into the atmosphere.

Open-pit mining is an extremely effective surface mining technique for extracting minerals, coal and other useful materials that are covered by relatively thin overburden layers. However, it takes the right equipment to penetrate the surface rock and reach the underlying layer in a timely and efficient manner.
