Presentation Transcript. Explanation: Openpit mining, also known as opencut mining, and strip mining, refers to a method of extracting rock or minerals from the earth by their removal from an open pit. Most of the time, when the mining company is done with it, the pit is used as a landfill. A landfill is used as a dump to get rid of our garbage.
