Best mining method?

Jul 29, 2019Manual mining is much faster when it comes to getting specific resources. Setup consists of digging down to the level where your target is and then swinging away at things - or simply running through a cave system that happens to be at the right level. Caving's probably best but unfortunately nearby caves are a bit of a limited resource.

Palabora Mine

Palabora had been in operation since 1956, where it was initially mined through open-pit methods, then later in its life by underground block caving. In order to extend the mine-life of the project, a second block cave production lift was required. Byrnecut was awarded the contract to develop the parallel declines required to exploit the second

How Underground Mining Works

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.
