The limestone was generally 18 to 24 inches above the coal, but only averaged 6 inches thick. The interval between the coal and limestone was black shale, with 2 to 6 inches of draw slate in some parts of the mine. Some horsebacks and small clay slips were noted. The coal contained some small charcoal bands and streaks of pyrite in thin, discontinuous bands. The floor was 12 to 18 inches of underclay. The mine was dry, which prevented heaving. Large boulders were sometimes found in the floor in the northeastern part of the mine. The bedding planes of the coal arched over the boulders, which had many calcite-filled cracks. The boulders had to be broken up with dynamite.
