Layer Updates:  We have added three layers showing surface coal mines, underground coal mines, and coal mine entries in Indiana into the Geology folder of the IndianaMap. These updated data were provided to the IGS by personnel of the Indiana Department of Natural Resources, Division of Reclamation, in November 2017. If you are a frequent user of these data, please use the links below to access the Layer Gallery to download data and metadata for each of these layers.

  • Surface Coal Mines, 20161231 (1:24,000) – Shows the locations and extents of surface coal mines for the period from the early 1900s through 2016. Mines can be differentiated based on mine type, mine number, source information, and dates of mining. Original source information includes company mine maps, field maps and notes of IGS geologists, IGS publications, Indiana State Mine Inspector Reports, several series of aerial photographs, and U.S. Geological Survey 7.5-minute quadrangle maps.
  • Underground Coal Mines, 20161231 (1:24,000) – Shows the locations and extents of underground coal mines. Includes locations for all documented underground mines that operated in Indiana since the late 1800s, through 2016. Mines can be differentiated based on mine type, mine number, source information, and dates of mining. Original source information includes company mine maps, field maps and notes of IGS geologists, IGS publications, and Indiana State Mine Inspector Reports.
  • Entrances to Underground Coal Mines, 20161231 (1:24,000) – Shows the locations of entrances to underground coal mines that have operated in the coal region of Indiana since the mid-1800s. Includes information on entrance type (hoist shaft, other shafts, slope, unknown), depth, mine number, and source information (map number). Derived from the Indiana Coal Mine Information System (CMIS), hosted by the Indiana Department of Natural Resources, Division of Reclamation.
