Geological Problems Reported

The Herrin Coal had a series of faults and rolls in the main north entries, most with displacements ranging from 6 inches to 7 feet. Several northwest-southeast trending faults cut through the mine in both seams, in some cases limiting development and in others not disrupting the pattern of mining at all. The displacement along these faults was often not noted on the source map. The source map for the Springfield Coal noted “bad top” along the east side of the mine. This probably prevented expansion in this direction, both for this mine and for Peabody No. 44 Mine’s (mine index 129) westward expansion in the same area. There is some faulting in this area as well.
