This study is directed towards better insights into the sedimentological variables which affect coal exploration and development. With continuing growth of the coal industry, a better understanding of the geologic conditions governing coal quality and quantity is necessary for efficient coal development and utilization. With most of the strippable, thick coals under development, the importance of understanding depositional systems within the ancient coal-forming swamps becomes more important as more deep mines are opened in thinner seams. The development of these coal mines benefits from an understanding of rapid facies changes characteristic of coal swamp environments that anticipate coal-seam discontinuities, coal-seam splits, and roof fall problem areas. Prediction of these facies changes is necessary for safe and efficient mine operation.
