Is an old working under a property here?
The mine records hold 3 named mine sites inside the city or town limits, 1 of them worked out or abandoned; the old survey maps add 1 hole drawn inside the city or town limits, 0 of them shafts or tunnels. The mineral the records name is construction sand and gravel.
A point in either file is a location, not a property line: the sheet shows the opening on the surface, not the rooms under it. The record that shows what runs under a parcel is the mine map. The OSMRE National Mine Map Repository holds scanned underground mine maps and answers requests for a named mine or an area. Coverage is automatic in the 26 mandatory counties (Athens, Belmont, Carroll, Columbiana, Coshocton, Gallia, Guernsey, Harrison, Hocking, Holmes, Jackson, Jefferson, Lawrence, Mahoning, Meigs, Monroe, Morgan, Muskingum, Noble, Perry, Scioto, Stark, Trumbull, Tuscarawas, Vinton, Washington) and optional in 11 more.
