Geological Problems Reported

A major fault was present, with a 200-400 foot gouge zone and 35 feet of throw. The roof consisted of a dense sandy gray shale that tended to fall in irregular masses. Generally 24 to 36 inches of top coal was left to support and protect the roof. Considerable gas seeped out of the face. The coal seam in this mine did not have the flexure noted in other Franklin County mines, just a gentle undulation with no steep grades to hinder haulage. The coal contained a very small number of slips. A few pyrite balls and streaks were present in the lower bench. The underclay did not heave.
