Underground mining (hard rock)

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal

The Actual Difference Between Surface and Underground Mining

Surface mining is suitable for large, low grade ore deposits which occur below a thin layer of rock, or alluvial deposits found in sand and riverbeds. Underground mining is used for small, high grade deposits covered with a thick overburden (soil and rock above the ore), or for deep and sloping deposits.

The Mining Process Introduction underground COAL

The Mining Process. Once a mining lease has been awarded to an operator, exploration (i.e. evaluation of the resource) takes place, followed by a planning and development process before excavation or mining begins. The initial task is to gain access to the seam from the surface by some means (shafts, drifts, etc see Access to Seam from surface section for these terms). Once access has been

Tailingsfo Backfill of Tailings to Underground Workings

The tailings are generally mixed with a binder, usually cement, and then pumped underground to fill voids and help support an underground mine. For example a room and pillar mining operation that uses backfill will be able to extract the insitu pillars containing ore. This is possible due to the cemented backfill acting as a support and preventing heading collapse and problems with
