Opencut Mining or Underground Mining Which Is Better?

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. Yet, it’s only viable when the materials are reachable after removing only a small layer from the

Underground mining has a lower ground footprint than open pit mining. The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining
