Geological Problems Reported
Most of the roof was black Anna Shale, with a series of slips that made an unstable roof. Pods of gray shale roof also had large slips that weakened the roof. Roof falls were generally minor, as bolting to limestone (30 inches to 17 feet up) was the common practice. Some of the bolts failed nine years later, and the source map shows numerous roof falls. Rolls were reported where both the top was lowered and the bottom was raised. At least one large clay dike was present, which pinched out in about the middle of the seam. A large clay dike fault was present, with a throw of about 5 feet, with another series of parallel slips that seriously weakened the roof. The source map shows several faulted areas with 5 to 10 feet of displacement. Gas emission was high on the freshly-mined face. Partings in the seam were present in the northern and eastern parts of the mine that resulted in a product with a high reject rate relative to the coal in the rest of the mine.
