Grosvenor Mine Spontaneous Potential R 70 Tests done on Virgin Coal. LW 104 Coal has been drained of inherent moisture through gas drainage. Is this trying to compare apples and oranges?

Why is Dr. Beamish talking about testing virgin coal samples from where LW 108 is planned to to be in future?

I do not pretend to have great knowledge of the tests done, but surely Dr. Beamish is comparing apples and oranges.

The coal in LW 104 has allegedly had extensive gas drainage of the Goonyella Middle Seam done.

Gas does not release from the coal until the water (inherent moisture) has been drained from the coal.

Therefore the direct relationship Dr. Beamish is basing his whole hypothesis on, to me is fatally flawed from square 1.

The coal in the goaf as it is self heating, does not have to remove much, if any inherent moisture.

Therefore the energy is retained in the coal and any cooling effect from inherent moisture does not exist.

I may be slow on this topic, but it does not make sense to me at all
