Open-pit is one of the most common mining methods used and starts from the earth's surface, maintaining exposure to the surface throughout the extraction period. The excavation usually has stepped sides to ensure the safety of the miners and a wide ramp where equipment can travel, allowing the product to be removed efficiently from the site.

2021-6-18 There are five basic types of surface mining, including open-pit mining, strip mining, dredging, mountaintop removal, and high wall mining. All of these methods remove the waste material or the overburden, which is above the desired resource. Often, surface mining is preferred over underground mining, or subsurface mining, for numerous reasons.
