RP, HERAccording to the mine notes, some pillars were drawn where the roof permitted.

Geological Problems Reported

The roof was 0 to 3 feet of black shale that slaked readily on contact with air, and which was overlain by 40 to 50 feet of gray shale. A former stream channel cut down to within 10 feet of the coal. Where the rooms struck this roof, the roof fell and let in sand and a great deal of water. Gas was occasionally found in pockets in the coal. Numerous horsebacks, rolls, and sulfur balls were present in the roof. The seam contained a persistent clay band 6 to 10 inches above the floor. The clay band varied from a knife-edge to 2 inches thick, and contained considerable sulfur. The top 6 inches of underclay heaved considerably.
