Geological Problems Reported

The roof varied between limestone caprock that was up to 12 feet thick, and gray shale where the limestone was eroded. The black shale, which was rarely present under the limestone, ranged from 6 to 24inches thick, and was under 12 to 24 inches of clod, a medium gray, marly clay. The coal was softer where the gray shale made up the roof, and the gray shale roof was difficult to keep up. Horsebacks were noted, some up to 2.5 feet wide and filled with a soft, medium gray clay. The horsebacks cut through at an angle near vertical to a 45-degree angle, fingered out into the coal on both sides of the horseback, and were accompanied by a slight coal displacement and the resultant slips. The coal contained hills and valleys, with the worst having a 10% grade that required two mules to pull one car. The coal was thinner on the hill portion and thicker in the valleys. Charcoal was present in lenses and bands. Some clay partings were seen in the coal. The coal was present as three benches, but the charcoal layer separating the benches was rarely present and was therefore no advantage when shooting off the solid. The upper bench had pyrite in lenses, generally 1 inch by 3 inches. The pyrite in the middle coal was present as facings. The underclay was 6 to 8 feet thick, and heaved only in abandoned rooms.
