Geological Problems Reported

This mine had an irregular roof that lead to a variety of problems. There were numerous slickensides, limestone "bosses" and faults throughout the mine. A channel that ranged from several hundred feet to 1000 feet wide extended throughout the mine, which greatly affected mining. Concretions were found at the top of the Herrin Coal in some areas. These features, along with a shale roof that lacked competency and allowed for water seepage, created roof problems. Roof falls were reported.
