Surface mining - strip, open pit, mountaintop removal, dredging
Surface mining is a form of mining in which the soil and the rock covering the mineral deposits are removed. It is the other way of underground mining, in which the overlying rock is left behind, and the required mineral deposits are removed through shafts or tunnels.. Surface mining is basically employed when deposits of commercially viable minerals or rock are found closer to the surface ...

Underground Mining in Australia & Primary Methods
Longwall Mining: Large coal blocks are identified underneath the earth's surface and usually fit in the dimensions of 100-300m in width by 1000m to 3000m in length. This block of coal is then extracted in slices by undercutting, where it is then blasted and drilled. The remnants are placed on conveyor belts until the entire block is extracted.

How Underground Mining Works | HowStuffWorks
The least common method in hard-rock mining, block caving, is typically saved for low-grade ore. It involves drilling a section of ore at the very bottom of the deposit and then blasting to make the roof collapse. Gravity then takes over, as the ore above the blast site fractures and collapses in succession as support is withdrawn.
