National Mine Map Repository Office of Surface Mining
The Federal Coal Mine Health and Safety Act of 1969 established the Mine Map Repository The facility stores over 150,000 maps of closed and/or abandoned, surface, and underground mines throughout the United States The repository contains mines from the 1790s to the present day These maps are archived digitally and on microfilm (aperture cards)Coal extraction methods vary depending on whether the mine is an underground mine or a surface (also called open cast) mine Additionally, coal seam thickness and geology are factors in the selection of a mining method Coal mining Wikipediaoutside the mining area for placement and storage In the Midwest, where the surface topography and coal seams are generally flat, it is common to employ area strip mining in which the fragmented overburden is placed directly by large draglines in the space created where coal has been mined ()In some situations in the eastern United States, a coal seam occurring near Coal Mining and Processing Methods The National Academies

The Impact of Surface and Coal Mining on Environment Your
Underground mining of coal lowers the surface, breaks and damages the strata lying not only vertically above the extracted area but also the areas surrounding the coal seams over a considerable distance ie large land areas lying over unworked portions of the coal seams get destroyed by mining subsidence ADVERTISEMENTS:
