Underground mining methods are used when the mineral deposit is too deep underground to be practical and economical to mine from the surface. As with surface mining, different methods exist for extracting an underground resource, depending on the size, shape and grade of the ore body, such as: cut and fill, stope mining, block cave mining, longwall mining.
In each of these mining methods, various earthmoving 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. Blasting and grinding equipment are used to accomplish this task.
