This report describes the USGS surface-mining model for near-surface coal beds typically lying within 200 feet (ft) of . the surface (Luppens and others, 2008) but with depth varia-tions depending on regional surface-mining analogs. Mine modeling is part of a collaborative process that is integrated
Surface mining is a process whereby soil and rock overlying the mineral deposit are removed. There are two principle types of surface mining, strip mining and open-pit mining (see Fig. 8.8).Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock.
