Understanding Underground Mining Methods
Underground mining is a method of extracting ore, minerals, and other geological materials from beneath the earth's surface. It is utilized when the mineral deposit cannot be recovered efficiently by surface mining, or when the deposit is located at a significant depth, thereby requiring a tunnel-based approach to reach it.
