Lineaments: A Predictive Tool for Bad Roof.
Coal 1988 Mar; 25(3):94-96
This paper describes Bureau of Mines investigations of five landsat lineaments in the coal mining region of southwestern Pennsylvania to determine their geologic character, relation to subsurface conditions, and the means of discriminating one from another. The investigation include earth resistivity and very low frequency electromagnetic traverses, soil moisture sampling, and a correlation with coal mine roof conditions. The lineaments could not be detected by the methods used, suggesting that they might be a surface phenomenon unrelated to subsurface geologic structures or roof stability in coal mine workings beneath.
