Geological Problems Reported

A fault in the W¹/₂ E¹/₂ 26-T9S-R4E required an unmined 200 foot corridor to be left, except for entries that provided access to the coal on the eastern side of the fault. A faulted block prevented mining in SW SW 26-T9S-R4E. A northeast-southwest trending fault was present in NW NW 26- T9S-R4E. This low-angle reverse fault interfered with the general mine plan. With it, a zone of crushed shale made a bad plane of weakness in the roof, yet no apparent displacement of the coal seam took place in some segments of this fault. In most places the roof was excellent, consisting of a medium gray shale that was moderately hard, well bedded, and finely silty. One area of bad roof was noted on the source map in the northwestern part of the mine. Rolls were present in the mine, generally trending north-south, creating problems with mining and roof control. 60-inch roof bolts were used in those areas, whereas normally 30-inch bolts were used. The overburden decreased to the south and there was a splitting of the coal in the southern part of the mine. The coal thickness varied over the mine property. Occasional pyrite lenses occurred in the coal, mostly near the top of the seam.
