Surface Mining Underground Steep

2020-7-14Surface mining. Surface mining techniques are used when a vein of coal or other substance lies so close to the surface that it can be mined with bulldozers, power shovels, and trucks instead of using deep shaft mines, explosive devices, or coal gasification techniques. Surface mining is especially useful when the rock contains so little of the ore being mined that conventional techniques, such.
