Outlines of areas mined for the Wade Coal in Illinois. Mining in this seam ceased ca. 1940. This information was extracted from detailed coal mine data stored in the ISGS Coal Section library database. Lines delineate the approximate outer boundary of individual mines (if known) or general mined areas. Interior mine boundaries such as pillars or small blocks of unmined coal are commonly not depicted. Outlines have been compiled from a variety of sources. Outlines of areas mined before 1987 are commonly from source maps at scales of 1:62,500 or smaller. Outlines of areas mined since 1987 are commonly digitized at scales ranging from 1:4800 to 1:12,000. Mines whose extent is not known or which only mined a few acres are not included in this coverage. Additional information is available from the Coal Section of the Illinois State Geological Survey. Mine outlines from completed Coal Mine Quadrangle Studies were included in this feature class if applicable. An ongoing study, the detailed Coal Mine Quadrangle maps depict the best-known position of mine boundaries with respect to individual properties as located on a USGS topographic map image base. For a list of completed quadrangles please visit the ISGS Coal Section website or contact the Coal Section. This datafile was compiled and updated in 2014 in order to provide a current, state-wide data set showing surface and underground coal mines of the Wade Coal. Due to the wide range of source map scales, these data are suitable for regional applications only at the 1:100,000 scale or smaller.

This collection-level metadata provides a general description of historic Iowa coal mine maps scanned and stored as color (24-bit) TIFF images. The maps were usually prepared by a mining engineer and show the details of the mine workings, updated every second year. Most are blue print copies, but a few original linen maps are included in the collection. The maps are currently housed at the Iowa Geological and Water Survey. Each mapped mine site is represented by one to thirty-one maps. Multiple maps are typically sequential with updates being added biennially through the operating life of the mine. In this case, the most recent map was selected for georeferencing unless the map was unusable for any reason. Maps from Des Moines and the surrounding area were georeferenced with world files for a project supported by the Office of Surface Mining Reclamation and Enforcement in 2011-2012.
The National Mine Map Repository (NMMR) maintains point locations for mines appearing on maps within its archive. This dataset is intended to help connect the Office of Surface Mining Reclamation and Enforcement, other federal, state, and local government agencies, private industry, and the general public with archived mine maps in the NMMR's collection. The coordinates for mine point locations represent the best information the NMMR has for the location of the mine. As much as possible, the NMMR strives to find precise locations for all historic mines appearing on mine maps. When this is not possible, another feature as close to the mine as is known is used. This information is reflected in the mine point symbols. However, the NMMR cannot guarantee the accuracy of mine point locations or any other information on or derived from mine maps. The NMMR is part of the United States Department of the Interior, Office of Surface Mining Reclamation and Enforcement (OSMRE). The mission of the NMMR is to preserve abandoned mine maps, to correlate those maps to the surface topography, and to provide the public with quality map products and services. It serves as a point of reference for maps and other information on surface and underground coal, metal, and non-metal mines from throughout the United States. It also serves as a location to retrieve mine maps in an emergency. Some of the information that can be found in the repository includes: Mine and company names, Mine plans including mains, rooms, and pillars, Man-ways, shafts, and mine surface openings. Geological information such as coal bed names, bed thicknesses, bed depths and elevations, bed outcrops, drill-hole data, cross-sections, stratigraphic columns, and mineral assays. Geographical information including historic railroad lines, roads, coal towns, surface facilities and structures, ponds, streams, and property survey lines, gas well and drill-hole locations. Please note: Map images are not available for download from this dataset. They can be requested by contacting NMMR staff and providing them with the desired Document Numbers. NMMR staff also have additional search capabilities and can fulfill more complex requests if necessary. See the NMMR website homepage for contact information: https://www.osmre.gov/programs/national-mine-map-repository. There is no charge for noncommercial use of the maps. Commercial uses will incur a $46/hour research fee for fulfilling requests.

Please follow the instructions below for using this viewer and linking to additional map products that contain more information. Enter your address in the box below and click "Search Address", OR Pan/Zoom to an area. Address location is provided by ESRI geolocation service.Please check that the location is accurate. If the address was incorrectly geolocated, you may drag the map around to find the proper location.Consult the legend for types of mines displayed.Links to view additional information regarding the mines will appear below the map with a left click on the map.What is the yellow area on the map?Data ExplanationThese data were compiled by the ISGS for known underground and surface coal mines as well as underground industrial mineral mines. For more information including links to coal mine maps and informational directories, coal resource maps, and coal logs please see the County Coal Map Series.The underground coal mine points consist of mine entrances and may also contain uncertain underground mine locations. The underground mine proximity region incorporates coal mines as well as industrial mineral mines, and it was calculated and constructed using the methodology outlined in ISGS Circular 575. These generalized areas are not meant to replace site-specific studies; they conservatively illustrate areas overlying and adjacent to underground coal and industrial mineral mines that may potentially be exposed to subsidence based on 1) angle of draw from the edge of the underground workings up to the land surface, and 2) potential inaccuracy or uncertainty in mine boundary locations. Please see ISGS Circular 575. for a full explanation. Areas outside the proximity region also could be undermined. Old, undocumented mine openings have been discovered in many parts of the state. However, most undocumented mines were prospect pits or short-term operations that undermined only a few acres.The maps and digital files used for this study were compiled from data obtained from a variety of public and private sources and have varying degrees of completeness and accuracy. They present reasonable interpretations of the geology of the area and are based on available data. Locations of some features may be offset by 500 feet or more due to errors in the original source maps, the compilation process, digitizing, or a combination of these factors. These data are not intended for use in site-specific screening or decision-making.If you believe that you have mine subsidence contact your insurance company and download: Mine Subsidence in Illinois: Facts for Homeowners - Circular 569, 2013, 9 MB PDF fileData DisclaimerThe Illinois State Geological Survey and the University of Illinois make no guarantee, expressed or implied, regarding the correctness of the interpretations presented in this data set and accept no liability for the consequences of decisions made by others on the basis of the information presented here.ISGS Terms of Usehttps://isgs.illinois.edu/terms-useUniversity of Illinois web privacyhttps://www.vpaa.uillinois.edu/resources/web_privacyQuestions about ILMINES/Contact usEmail

Abandoned railroads and infrastructure from the anthracite coal mining industry are significant features in abandoned mine lands and are an important part of history; however, these features are often lost and masked by the passage of time and the regrowth of forests. The application of modern light detection and ranging (lidar) topographic analysis, combined with ground-truthing "boots on the ground" mapping, enable recovery of the location of these historical features. Waste rock piles and abandoned mine lands from historical mining locally appear as distinct features on the landscape depicted on the percent slope map. Abandoned, and in many places demolished, infrastructure such as breakers, turntables, rail beds, water tanks, tram piers, and bridge abutments, to name a few, were confirmed in the field and located with a global positioning system (GPS) receiver. This map captures the locations of many of the abandoned features from the coal mining industry near Forest City, Pen ...

Coal mining has occurred in Pennsylvania for over a century. The maps to these coal mines are stored at many various public and private locations (if they still exist at all) throughout the commonwealth. This dataset tries to identify the Mined Out Areas of the various coal seams in Pennsylvania. This information can be used for many environmental related issues, including mine land reclamation and determination of needs for Mine Subsidence Insurance. The information in this dataset was gathered from mine maps at these various locations so that the data can be readily available to environmental professionals.
County Coal Data and MapsThe Coal Resource Maps include structural elevation, depth, thickness, sulfur, and chlorine maps of the Colchester, Danville, Davis, Dekoven, Herrin, Jamestown, Seelyville, and Springfield Coals. The Coal Mine Maps are maps compiled by the ISGS of known mines: underground and surface coal mines as well as underground industrial mines. Buffer regions for industrial mineral underground mines were incorporated into the maps due to limited information regarding these mines. The size of the buffer region is dependent on the uncertainty or inaccuracy of the mine location based on the quality of the source material. For more information regarding industrial mines please contact the ISGS Industrial Minerals Section. The accompanying coal mine directory for each county provides basic information about the coal mines. Coal has been mined in 77 counties in Illinois and more than 7,400 coal mines have operated since commercial mining began in 1810. Our maps of known mines for each of these counties may help the public to identify mined areas. Please note, however, that the accuracy and completeness of the mine maps and directories vary depending on the availability and quality of source material. Little or no information is available for many mines, especially the older ones, because mining activity was not regulated or documented until the late 1800's. Even then, reporting requirements were minimal. In cooperation with the Illinois State Geological Survey, the Office of Mines and Minerals (a division of the Department of Natural Resources) is in search of old underground mine maps of Illinois. Many of the undocumented maps are believed to be in libraries, historical societies and personal files of old mine employees. The Department asks that anyone who knows of one of these maps, please contact the Department at (618) 650-3197 or by emailing brent.guttmann@illinois.gov(link sends e-mail). A map specialist will come to your location, if you wish. Otherwise maps can be mailed, or you may stop by one of our offices in Edwardsville, Springfield, Ottawa, or Benton. These maps will be checked against our existing inventory. If found to be a new discovery, they will be electronically imaged and returned to the owner (if requested). The Coal Logs are non-confidential coal log descriptions from the Coal Section's stratigraphic database located in the county. These are part of the basis for the coal resource maps. NOTE: A 1:100,000 scale county mine map with directory is available for purchase and can be ordered by contacting the ISGS at (217) 244-2414, or email at sales@prairie.illinois.edu(link sends e-mail). A 1:24,000 scale color plot version of each available quadrangle with directory is also available for purchase. The County Coal Resource maps have been supported, in part, by the contract Maintenance of Coal Resource and Mine Data from the Illinois Department of Natural Resources, Office of Mines and Minerals. Note: These maps are made available at this time in draft form only. They have not yet been reviewed to the normal standards of the Illinois State Geological Survey (ISGS) review process. They are made available in this manner as an "open file" in order to deliver products to our customers as fast as possible and to meet particular needs that we have encountered in public requests for this information. These maps are PDF files, requiring Adobe Acrobat™ for viewing. (Download Acrobat).
