  • Open Cut and Underground Mining iMINCO

    Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc.

  • Underground mining (hard rock) - Wikipedia

    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 ...

  • United Wambo open cut coal mine project - About

    Whilst open cut coal mining has previously been undertaken at United, over the last two decades the focus has been on underground mining. Underground longwall mining operations were approved to provide up to 2.95 million tonnes per annum (Mtpa) of saleable coal. Operations were suspended at United in March 2010 with the mine entering a period of care and maintenance. At that time,

  • Underground versus Open Pit Mining - Firwin

    If an area’s open pit mines are exhausted or impossible to build due to the inaccessibility of the desired resources, the mining process goes underground. There are several different ways to mine underground. You can build spiral tunnels that circle the deposit, sink vertical shafts adjacent to the ore, or create adits, which are horizontal excavations into the side of a hill or mountain ...

    10/10/2016  Strip mining is done on the surface; underground mining is done below the surface. In strip mining, the ore is extracted from the surface in layers resulting in a deepening artificial valley. This is done when the ore is relatively near the surface. In underground mining, mine shafts are bored or dug from the surface to the underground layers where the ore is located, and ore extraction takes ...
