Underground mining. Underground or "deep" mining consist mostly of two methods - room-and-pillar and longwall mining. In room-and-pillar, coal deposits are mined by cutting a network of "rooms" into the coal seam and leaving behind "pillars" of coal to support the roof of the mine. ... Open-pit mining utilizes blasting and mineral ...

Open – Cut Mining Monitoring solutions have a great impact in an open-cut mining environment where slope failures are of great risk.

When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited.

In 2014, Peabody agreed to establish an unincorporated joint venture project with Glencore to combine the existing operations of the Wambo Open-Cut Mine with the adjacent coal reserves of Glencore's United Mine. The main customers for Wambo coal are in Japan, Korea and China.
