Geological Problems Reported

An erosion channel approximately 75 feet wide ran E-W, crossing an entry about 2000feet from the shaft. Some small faults with 3 to 4 feet of displacement were present, as well as slips and rolls. The roof was 0 to 10 feet of black shale overlain by bluish gray limestone. The coal sometimes had a 1.83 foot thick dirty layer just beneath the roof, underlain by a 0.25-inch layer with streaks of coal and pyrite, but usually the upper 10inches was harder and brighter than the lower 38 inches. Roof falls caused 8 fatalities between 1899 and 1909. The seam locally had considerable dip while the general dip was 12 feet in 3 miles to the south. In 1909, Udden reported many pillars were pulled. Where bony coal was present, such as 500 to 600 feet from the shaft, heaving took place that no amount of timbering could halt. In some cases, heaving filled the entry. In some places, the floor was sandstone.
