Geological Problems Reported
Faulting throughout the mine displaced the coal bed in many areas. The amount of displacement was not specified in the ISGS mine notes nor on the source map. In general, the roof was good, but the source map shows “bad top” that apparently halted southward expansion in the southwest quarter of 9-T9S-R5E. Bad top was also a problem in a small area in the NE SW 9-T9S-R5E. Some areas of the mine also displayed rolls.
