these mining categories are: strip mining, open-pit mining, mountaintop removal, dredging and high wall mining. all methods of surface mining will remove the waste material, or overburden, above the desired resource. surface mining is often preferred to sub-surface by mining companies for several reasons.some examples for surface mining open cast mining open pit mining strip mining quarry mining placer mining some examples for underground mining important terms for surface mining open pit mine bench: is a ledge which forms a single level of operation where ore and waste are excavated.surface mining: main research issues for autonomous operations fig. simpli ed view of a mine operation mining automation 3.1 future of surface mining due to the uncertainty on the state of resources actual surface mining opera-tions needs to operate in a conservative manner to be able to satisfy customer requirements and shareholder prosurface 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 mining is the process by which commercially valuable mineral resources are extracted from earths surface. these resources include ores precious stones building stones and solid fuels
