This document discusses surface mining techniques. It begins by explaining open-pit mining, which involves forming a large hole or pit by extracting minerals. Strip mining extracts long, narrow strips of minerals using excavation equipment. The most common types of surface mining are open-pit mining, strip mining, and quarrying.
