Geology
Geological Problems Reported
The roof was a clay-rich shale (often referred to as “soapstone” in the mines of this area) that came down easily. Horsebacks occasionally cut out the top 3 to 12 inches of coal. Streamers of clay occasionally extended down into the coal from the roof. A ½ inch thick pyrite band was noted, and lenses of pyrite were seen near the center of the seam. Gypsum covered vertical fracture facings. The blue band was about 2 inches thick and 22 inches above the floor.
