In underground mining, information from surface borehole and geophysical methods of investigation can be supplemented by probe or core drilling underground. The resulting vast amount of data may be too much to be assessed manually, but computer software programs are available to deduce the best strategies for mineral deposit exploitation.

How Mining Works Resolution Copper

A look at the underground mining process The Resolution Copper deposit lies more than a mile beneath the surface. The most viable way to recover this ore body is by going underground, using a process called block caving. Block caving is a proven mining method using advanced technologies. Here's how it works. Ore, rock containing Continued

Open Cut and Underground Mining | iMINCO

Underground Mining. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc. Stopes are large openings or rooms connected by tunnels in which miners drill and blast the ore. A pillar or wall is left between each room (stope) to prevent the mine from collapsing.

Digging deeper: Mining methods explained Anglo American

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.
