Geological Problems Reported
One fault was noted in the southeastern part of the workings. The coal was 14 feet lower on the west side of the fault. In the southwestern corner of the property, just east of the principal brecciated zone, the coal was about 2 feet higher on the west side of a minor normal fault. The cap rock was 0 to 12 inches of limestone, with 18 to 24 inches of black shale beneath. The top 4 inches of coal “froze” to the black shale. A shale above the limestone was very fine grained and poorly bedded, with many slip fractures, and in some cases, this shale was the immediate roof above the coal. Where the limestone was not present or if the shale and limestone came down, the higher shale made a very poor roof, very difficult to keep up. Two partings were sometimes seen; a fusain parting that was 1/8 of an inch thick and 21 inches above the floor, and a pyrite parting 34 inches above the floor and 1/16 of an inch thick. In other areas, a 1/4 inch fusain band was seen 5.5 inches from the top of the coal, and two small pyrite bands were seen at 29 and 39 inches from the top of the seam, or three pyrite bands at 27, 32 and 36.5 inches from the top. The primary problem in the mine was fairly frequent occurrences of horsebacks, which cut out the coal and made the roof unstable. The underclay was over 3 feet thick and heaved occasionally, but not enough to be considered a problem.
