Geological Problems Reported
“The old works above this underground mine are full of water, presenting a worry since only about 20 feet of strata separate the No. 6 and No. 7 Coals.” Three roof falls of 7 to 10 feet of shale above the coal were noted. In places the topmost layers of coal were fractured and mixed with shale or clay in what could be called a “white top” disturbance. Elsewhere the contact of coal to shale gave the appearance of being an erosional surface. Clay dikes were present between the layers of black shale roof. Coal balls were present in the mid-to-upper part of the seam in some places. A major problem in this mine was the variability in thickness as well as quality. The coal was generally 7 to 8 feet thick, but pinched down to as little as 2 feet. Thin coal was due to rolls in some instances, erosion of the upper portion of the coal in some instances, and in other cases the thin coal was depositional, topographic highs where less peat accumulated. This caused the mine output to be high in ash content as the continuous miner took in portions of the roof and floor where the coal thinned. “Sulfur is said to vary from 2.2% to 4.1% and Btus from 11,200 to 11,800 within the small area already mined.”
