Strip mining: The targeted removal of surface layers to reveal the useful seams underneath. By contrast, subsurface mining requires mining a vertical shaft into the ground, from which lateral tunnels are excavated at different depths to reach the ore body. Vehicles move the ore from the mining face onto conveyors which carry the ore to the shaft.
