Geological Problems Reported
A fault trending NNW-SSE crossed the eastern side of the mine, with a displacement of up to 3 feet. The downthrown side was on the eastern side of the fault, and the coal was badly shattered on this side as well. The cracks were parallel to the fault. Most of the fracturing extended E-W, so that roof falls were most common on N-S entries. For that reason, rooms were run E-W. Limestone was deposited directly on top of the coal in part of the mine. As the roof graded to limestone, a hard, sandy, calcareous (“bastard”) shale was immediately above the coal for a considerable distance along the entry. This rock was somewhat slabby and commonly fell. The remainder of the roof was generally black shale. Up to 10% of the shale roof was a light gray shale, called “white top”, up to 5 feet thick. The coal was of better quality under the white top. The top of the coal was irregular, but the contact was clean and often contained pyrite plates. Pyrite was present in vertical fracture facings but was not persistent. A few pyrite nodules were noted. The blue band averaged 1.5 inches thick (ranged up to 3 inches thick) and was present 3 to 12 inches above the bottom of the seam. A fairly persistent clay and pyrite band was present 2.5 to 3 inches above the blue band. The thickness of this band varied, averaging about 0.25 inches but ranging up to 2 inches thick. A layer of pyrite lenses was sometimes present 8 to 10 inches above the blue band. The mine was dry, but the underclay heaved somewhat after areas were abandoned.
