Wirtgen Surface Miner Technology Maximizes Output at Indian Coal Mine. in Industry News Issue 02_2020 8. May 2020. Indian company uses highly productive and extremely reliable Wirtgen 220 SM surface miner, which specializes in soft rock mining, in a coal mine in the Indian state of Odisha.
#0183;#32;Surface mining for coal has taken place in the Central Appalachian region of the United States for well over a century, with a notable increase since the 1970s. Researchers have quantified the ecosystem and health impacts stemming from mining, relying in part on a geospatial dataset defining surface minings extent at a decadal interval.

Expert System: This is one of the first systems planned for selecting equipments in surface mining in 1987.
These mining categories are: strip mining, openpit 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 subsurface (underground mining) by mining companies for several reasons.

Surface mining is expected to see longterm growth according to research by Future Market Insights. Surface mining refers to the mining technique where the overlying layer of soil and rock is removed, followed by the recovery or excavation of the underlying minerals.
Mining production in South Africa fell % yearonyear in September of 2020, following an upwardly revised % decline in the prior month and compared with market expectations of a % drop. It was the seventh consecutive month of decreases in mining activity but at the softest pace in the current sequence, helped by the further relaxation of lockdown restrictions. Output fell less mostly
Surface mining, including strip mining, openpit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.
