Geological Problems Reported
The roof over much of the mine was poor, the exceptions being areas where the caprock was present. The caprock was 2 to 3 feet of limestone, underlain by 2 feet of clod. The clod’s thickness varied, being thick in sloughs and depressions (up to 7 feet) where it made a very bad roof, and thin on rolls. The clod contains concretions (up to 2-3 ft diameter) in some places. Slips and faults were common in some parts of the mine, and clay seams were present along fault planes. The faults showed displacement of 4 to 10 inches. The roof was bad in areas with slips. A gray band of pyrite was present in the lower half of the coal, and pyrite concretions were seen at various places in the seam. The concretions were easily separated from the coal. The floor was sandstone.
