Geological Problems Reported
The gray shale roof did not require a great deal of timbering. A few pyrite concretions were present in the roof. The main roof problems came from the numerous horsebacks in the mine. The seam was often broken by slips filled with roof clay. Two persistent clay bands were present in the seam. The upper clay band was about 18 inches above the floor and was about ½ inch thick, and contained a lot of pyrite. The lower clay band was between 2 and 3 inches above the floor and was about 3 inches thick. Mother coal was common in the seam as well, so that the coal was sooty.
