Geological Problems Reported

All areas except the southeast portion of the mine were affected by fractures. The fractures trended northwest-southeast, and displacement ranged from a few inches to about 2 feet. These fractures were interpreted as faulting rather than compactional slips. Coal was eroded in the area of a sandstone channel in the western part of the mine. The channel halted expansion northward in westernmost part of the mine, but in the northern part of the mine, an entry was driven through the channel. In the southern part, the Crown III Mine (mine index 0996) worked eastward to the channel.
