Geological Problems Reported
In some places, the surficial materials were within 15 to 20 feet of the coal. Where the rock was thin above the coal, the roof tended to come down and allowed water into the workings. Those were the only wet places in the mine, and were the chief difficulties in working the seam. However, after the detailed description, G. H. Cady (7-26-1918) noted that the occurrence of these falls were few as compared to other mines near Farmington. The immediate roof above the coal was a persistent black shale that stuck to the coal. The shale was kept up if possible but that was difficult. Above the black shale was up to 10 inches of clod with 18 inches of limestone above the clod. A little pyrite was seen in the seam, and two clay bands were noted – one about 8 inches below the top of the coal and the other about 18 inches above the bottom. Relatively few horsebacks were seen.
