The source map indicated water was a problem in the westernmost part of the mine. The roof was mainly black slate with very little draw slate, but in some areas it was grey shale, which came down with the coal. The black slate also contained many concretions. There were some small slips in the roof that required some timbering. Pyrite stringers and lenses were found throughout the coal.
