Roof Fall Study, Pocahontas No. 3 Seam. Research and Development Contract to Conduct an Engineers Study of Coal and Coal Measure Rocks
The detailed geology in portions of five underground coal mines in southern West Virginia, were mapped, tabulated, and analyzed with respect to roof conditions. Cross-sections and maps were constructed to illustrate roof rock types and their distribution and structure. Numerous data were compiled on coal cleat orientation.
