Geological Problems Reported
The roof contained coal balls and slips (one death was caused by each of these circumstances). The roof of the Springfield Coal was 3 to 4 feet of black shale that seemed bonded to the coal with pyrite. Often 2 to 5 inches of coal were left with the roof. Horsebacks were very common in the Springfield Coal, occurring every 25 to 30 feet. The Springfield Coal contained thin streaks of plate-like pyrite that were difficult to remove from the coal. The Colchester Coal was very hard and pyrite concretions were common. As well, a continuous band of pyrite occurred 4 to 8 inches above the bottom of the seam, along with numerous vertical plates of pyrite and calcite. The floor heaved somewhat.

Notes
- ↑ These drop shafts connect the two seams, but did not extend to the surface. They are shown on the accompanying map as “uncertain type of opening” point symbols, and are shown only on the Colchester Coal map. The mine notes and Coal Reports both refer to these as slopes. All coal was hauled to the surface from the lower seam.
- ↑ Production prior to 1882 is unknown.
- ↑ Production after map date
