Open Cut Mining

When operating in an open-cut mine environment, the monitoring of the site for slope or rock movements is vital to ensure the safety of employees and equipment, as well as operational efficiency. As an open cut mine gets larger and steeper, slope design becomes more complex. This means ensuring the right monitoring solutions are in place to ...

Open-cut mining. Opencut mining gets its name because that's exactly what this type of mining looks like, a big open pit. This type of mining allows for the extraction of minerals that aren't very far under the surface. The process keeps the activity from going deep underground. This has many advantages.

The Mechanics of Open-Pit Mining. Open-pit mining involves the removal of large quantities of overburden (the soil and rock overlying a mineral deposit) to access the ore body. The process begins with the excavation of a large pit, which grows progressively wider and deeper until the mineral resource is depleted.
