Although underground tunnel footage production is commonly looked at in “tonnage” or “footage” per day, mining top-quality mineral specimens and gem material is a completely different form of tunneling. The smallest fracture or imperfection can reduce the value of the product.
Mineral Extraction - The Environmental Literacy Council
The three most common types of surface mining are open-pit mining, strip mining, and quarrying. Whether the surface is broken up by explosives, as is common in quarrying, strip and mountaintop mining, or by large pieces of equipment, common in open-pit mining, the principle remains the same—the overburden is excavated and moved elsewhere so ...
What is Underground Mining? (with pictures) - wisegeek.com
May 29, 2019· Underground mining is a technique used to access ores and valuable minerals in the ground by digging into the ground to extract them. This is in contrast with techniques like open pit mining, in which the surface layers of ground are scooped away to access deposits, or mountaintop removal, in which the top of a mountain is simply shaved off to access the ore inside.

Environmental Risks of Mining
Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
