Interactive Map of Ohio Coal and Industrial Minerals Launch Page
The interactive map of Ohio Coal and Industrial Minerals depicts the locations of mines and quarries that are capable of producing coal, Limestone, Dolomite, sand and gravel, salt, sandstone, conglomerate, clay, shale, gypsum, and peat. Some of the locations of the mining operations depicted since 2006 are based on Global Positioning System (GPS) coordinates obtained in the field by ODNR, Division of Mineral Resources Management (DMRM) mine inspectors. In 2009 ODNR undertook an effort to depict the remaining mines in more accurate locations. The mine locations reporting in the 2008 report were located based on observations from high-resolution aerial photography obtained from the Ohio Statewide Imagery Program (OSIP). OSIP imagery was taken during 2006 and 2007 flights and delivered for public use since the release in 2008 of the 2007 report. A few sites still remain that have not been located using this accurate processes. These sites have been located using DMRM permit maps and should be considered approximate. The base map includes county and township boundaries, highways, railroads, as well as major rivers and lakes.
The interactive map of Ohio Coal and Industrial Minerals is part of the legislatively mandated Report on Ohio Mineral Industries, produced annually by the ODNR Division of Geological Survey. The Report on Ohio Mineral Industries contains detailed information (owner, production, sales, value, employment, wages, geology, and end-use) on active coal mines, coal processing facilities, and permitted industrial-mineral operations in the state. The full report with text, figures, and maps in an Adobe Acrobat portable document (PDF) is available at:
