2. Mining Methods
2. 2. Mining Methods. Left: Open Pit Mining. Right: Underground Mining. In each of these mining methods, various earth-moving equipment including shovels, dozers, hauling trucks, and loaders are used to remove and transport the ore. However, the first step is to loosen the rock in the ore body so that it can be moved and processed.
The Main Types of Mining and their Differences
The main difference between surface mining today and mining carried out in ancient times is the types of equipment used. As some minerals exist at the surface or just below ground, surface mining is still the most appropriate method for extracting them. Surface mining is also referred to as open-pit mining.
