Abstract: 

The Ohio Department of Natural Resources (ODNR), Division of Geological Survey (Ohio Geological Survey) performed an estimation of the remaining and available resources of the Pittsburgh (No. 8) coal bed in Ohio. This study represents the first statewide estimation of Pittsburgh coal resources in 14 years. The Pittsburgh (No. 8) coal is the most heavily mined coal bed in Ohio, representing 64 percent of the total coal mined within the state. Data points were collected to create base-elevation structure and isopach maps using Geographic Information Systems (GIS) technology. The base elevation structure raster was constructed from 47,714 data points using the Natural Neighbor interpolation technique. Sequential Gaussian simulation was used to create isopach maps from 2,725 data points, which were then summarized by county to obtain coal tonnages. Project results reveal that the Pittsburgh (No. 8) coal bed had an estimated 7.9 billion short tons of coal in Ohio before mining. Of that amount, 3.4 billion short tons have been mined and approximately 4.5 billion short tons remain. Of the remaining resources, 348 million short tons are available for surface mining and 2.6 billion short tons are available for underground mining. The majority of the available resources exist in Belmont County (777 million short tons) and Monroe County (1.1 billion short tons). Given that the current rate of mining for the Pittsburgh (No. 8) coal is 14 million short tons per year, these resources will last for more than a century.
