Geological Problems Reported
Rolls and faults were present throughout the mine, and some interfered with mining. A large fault prevented westward expansion of the mine. The roof was generally good, with a 4-inch layer of “draw slate”. The coal contained pyrite lenses in the upper portion, and calcite or gypsum fracture fillings throughout the seam. The thicker coal was in the southern part of the mine. The source map also shows that the coal was split by a shale band on the western side of the northern part of the mine (NE SW 30-T9S-R6E).
