I understand this Rob, they are all seams within the Mammoth vein I live very close, buy about 900 tons of their coal a year.
Yes, I see that the veins are very close in proximity. I think they also join in some areas? Regardless, I think you would agree that depending where you are mining, the coal from each respective seam can have different characteristics.

"Bank coal" usually refers to coal that was previously mined and discarded (often left in huge piles, or 'banks') because the size was not in demand, or because the quality was not what they were looking for. For a long time, hand-fired equipment was the only game in town...so rice & buckwheat had no market. I am surprised that there is even much of it still around, considering the co-gen plants that burn it and the market for the smaller sizes.
