## **Abstract** \n\nThis dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied. Metadata was not provided and has been compiled by the Bioregional Assessment Programme based on the known details at the time of acquisition.\n\n\n\nThe following data was requested for the Hunter BA region from the NSW Department of Trade and Investment to provide/give access to the following information. \n\nSpatial information (maps, GIS layers, images) showing:\n\n\\*\tThe xyz dimensions of the footprints of underground (i.e. both longwall and bord-and-pillar) mines excavated from 1980 to 2012, updated once every 4-years, in the Hunter bioregion. \n\n\\*\tThe xyz dimensions of the footprints of open cut mines excavated from 1980 to 2012, updated once every 4-years, in the Hunter bioregion, including details of rehabilitated areas, if available\n\n\\*\tThe z dimension (elevation) relative to sea level, i.e. the AHD reference.\n\nOther information as follows\n\n\\*\tThe company that undertook each excavation\n\n\\*\tFor underground workings, whether longwall or board and pillar mining was used, and if the latter, whether the pillars have been subsequently extracted.\n\n\\*\tMine water discharge volumes between 1980 and 2012, or until mine water pumping ceased, as available.\n\n## **Dataset History** \n\nThis dataset was supplied to the Bioregional Assessment Programme by a third party and is presented here as originally supplied.
