Two faults were noted, one in the main west entry and one at the face. Both faults extended into the Davis Mine (mine index 3146). The faults emitted gas when first encountered, and moderate amounts of water. The cap rock was a limestone about 20 feet above the coal. Gray sandy shale was the immediate roof above the coal. It fell in slabby layers, sometimes as high as 20 feet. Rolls cut into the seam from the roof and floor. Top coal was left to support the roof, generally 26 to 30 inches. The blue band was in two layers. Other impurities included pyrite-bearing clay bands. These generally separated easily from the coal. The floor heaved badly.
