A 1921 gas explosion killed 12 miners, and a 1920 gas explosion killed 1 man. Faults were present throughout the mine, most trending northwest-southeast. Some halted mine expansion. Others were mined through, but the amounts of displacement were not noted on the source map. Above the coal was a shale that made a competent roof, except during humid summer when the shale “sweated” and slabbed off, producing many falls. The northernmost part of the mine had several areas identified as bad top. This same area was also shown on the source map to have a two-foot split of rock in the middle of the coal. In the southern part of the mine, an area was labeled ‘squeeze’. Some pyrite concretions and lenses were found in the coal. The floor, which was 2 to 3 feet of shale, heaved some, but was underlain by hard limestone.
