• Geographical data including abandoned railroad lines and stations, coal towns, surface facilities, roads, ponds, streams, and property survey points.
• Districts, townships, sections, ranges, counties and municipalities, latitudes and longitudes, elevation bench marks, and surface elevations Gas, oil wells and drill-hole locations

The NMMR offers scanned map images from 200 dpi to 600 dpi on CDs and DVDs, microfilm prints, and microfilm copies. Newly donated mine maps will be scanned in color. Microfilm mine maps are available for viewing by appointment. The following is an example of some of our clients and the types of requests we receive:

Private Citizens/Homeowners: Inquiries about past mining activity underlying their residence/community to access potential property hazard information related to past coal mining. They may also request information pertaining to mine subsidence insurance. There is no charge to private citizens and homeowners for the services of the NMMR.

Consultants: Identify specific project areas and request information on various mine seams, mine depth, extent of mine, closure dates, detailed maps of mine workings, and mine operators to use as a basic source of geological and engineering data.

Government Agencies: Request for information on subsidence, acid mine drainage, highway and bridge construction, mine maps for public display at municipal buildings and maps for local town meetings, mine fires and mine rescue operations. The information may also be requested to conduct health and safety activities, such as mine rescue operations or to correct adverse environmental impacts resulting from landslides, subsidence, mine fires, etc. There is no charge to government agencies for the services of the NMMR.

Developers & Contractors: Request mine maps to determine extent of mine workings and mine depth for pre-construction. They require information on coverage over mines to determine a need for support structures or to assist in making decisions relative to land use, foundation design, etc.

Architects: Utilize mine map information in their design of structures. The information is necessary for decisions on the types of foundations and weight displacements.

Realtors: Request information on abandoned mines within a given municipality. Their primary concern is to identify the distance of mines that underlie individual homes and whether information on mine subsidence insurance is necessary.

Mining Companies: Utilize mine maps to prepare mine permit applications for new or existing mines. Consume considerable time researching map files and request mine map copies for further evaluations.

In addition to the services named above, there are many other services that the NMMR can provide. Including but not limited to mine map images on CD/DVDs, microfilm copies, printed copies, information on obtaining mine subsidence insurance, computerized research assistance, and copies of indices listing the NMMR inventory.
