Geological Problems Reported:[edit | edit source]

Faults trending E-W were noted on the source map. Roof falls were relatively common, and were relatively large (size not given). The roof was generally silty shale and siltstone, with occasional fine sandstone beds that were 1 foot or more thick. At the base of the slope, shearing created an unstable roof that was difficult to support with roof bolting. In some instances, most of the movement along the shear was horizontal, but in other areas nearby and few feet up into the roof, the shearing dipped at various angles and trends, even along a single shear surface. There were numerous indications of soft sediment flow before complete lithification of the roof sediments or the coal. In the area at the slope bottom, the 5 foot mechanical bolts were supplemented with 8 to 12 foot resin bolts, often with “bacon strips”, thin metal bands attached to adjacent roof bolts to help support smaller pieces of roof rock. A clay dike was seen, although clay dikes are rare in the Herrin Coal. Rolls were large (across multiple entries) and mine plans were altered to leave pillars under them where possible. Pyrite and siderite in lenses and nodules were found. The lenses were up to 0.2 feet thick and more than 1 foot in diameter. The sulphur content was generally less than 2%.
