Geological Problems Reported

Gas was abundant in places. Northwest-southeast trending faults were present in the eastern and western parts of the mine. The roof was good, except for two layers of “draw slate”. The first layer was taken down with the coal, and the second layer came down after a few months. The coal contained a pyrite layer near the top of the seam.
