Mining : What is Mining? What are the 4 mining

Sub-surface mining can be classified according to the type of shafts used, the method of extraction or the technique used to reach the deposit. Drift mining uses horizontal access tunnels, diagonally sloping access shafts are used by slope mining, and shaft mining uses vertical access shafts. Mining requires different techniques in hard and soft rock formations. Highwall mining. Highwall mining is another surface mining form that has evolved from auger mining.
