Geological Problems Reported
This mine is about 100 feet above old works in the Springfield Coal, the Peabody No. 47 Mine (mine index 0124). Some faults were found, with displacement up to 30 feet. The roof around the air shaft bottom consisted of 6 feet of Energy Shale overlain by 2 feet of Anna Shale, and in turn overlain by Brereton Limestone. The Energy Shale made a competent roof generally, but slaked badly in north-south-directed entries. For this reason, the general mine plan was offset about 45 degrees from a north-south orientation, which avoids the regional compression that causes falls in north-south oriented entries. Some areas of the Energy Shale had discontinuous faults that did not extend down into the coal. In other areas, the Anna Shale was the immediate roof and the Energy Shale was present only as thin, discontinuous, lenticular deposits. Some of the Energy Shale lenses were large, 1,000 feet or more across. The Anna Shale generally made a competent roof, even though numerous wide joints occurred in some areas. Concretions were also present in the Anna Shale, and they generally were predictors for the limestone being present within 3.5 feet above the shale. Roof falls occurred in areas with high angle fractures. The coal contained calcite along cleat fractures and pyrite as “goatbeards” and fracture fillings. The bed had no noticeable dip and was practically free of undulations and rolls.
