Geological Problems Reported

One miner was killed by a gas explosion in 1921. Some faults were noted in the mine. The roof was generally an irregularly bedded gray shale that did not make a good roof, and the soft upper portion of the coal was left to support the shale. When the top coal was mined on retreat, the shale came down readily. At least one roof fall was noted on the source map. Rolls were present and occurred mostly in swags. The floor was a dark gray shale that heaved badly.
