Geological Problems Reported
The mine outline shown on the accompanying map indicates the presence of many faults and dikes throughout the mine. Most trend northwest-southeast. The most bothersome dike cut diagonally through 13 and 24-T8S-R6E, and was 25 feet wide in the entry northwest of the hoist shaft, flanked by a total of 12 feet of naturally coked coal. At least two more dikes were noted, both in the northeastern part of the mine. One southwest-northeast trending fault, that had 35 feet of displacement, was noted south of the air shaft. The roof contained many slips, which caused many roof falls. One large area in the northern part of the mine (13-T8S-R6E and 18-T8S-R7E) was unmined because the coal was split. The source map indicates the upper split was 4.0 to 4.5 feet thick, with 1 foot or less of coal in the lower split below 2 feet of rock. Pyrite lenses were common in the coal. The floor had many slips, but no heaving was reported.
