Geological Problems Reported
Some gas problems were noted in 1884, but increased ventilation remedied the situation. The roof was 3 to 5 inches of black and blue-gray shale, overlain by 2 to 18 inches of limestone cap rock, with 40 feet of gray shale above the limestone. Horsebacks ranged from common to abundant and some were quite large. This increased the cost of mining so that the mine was sometimes not economically competitive. Clay veins were present in the coal, and the upper part of the seam contained small pyrite streaks and many pyrite concretions. The floor clay was 4.5 feet thick and heaved badly when wet.
