Faults and slips were noted at the mine. The slips required timbering. The faults had irregular displacement, sometimes only 12 inches. Top coal (2 to 4 feet) was left to support the roof, but this was pulled when the rooms were worked out. The roof was a light gray sandy shale that was 20 to 60 feet thick. As machine mining took over, usually only 6.33 feet of coal was mined. The blue band ranged from 1/4 to 3 inches thick. The seam had an irregular bottom surface. The floor was 6 feet of fire clay.
