1. Mining open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

What is Underground Mining? (with pictures)

24-09-2020· The first step in underground mining is development mining, in which shafts are dug into the site to make the ore accessible. During this phase, along with shafts, things like electricity are installed, along with lifts and shoring to support the walls of the mine so that it will not collapse. Once the mine is developed, active production mining can begin, with the ore being extracted by hand

How Underground Mining Works HowStuffWorks

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
