Prosity in coal is of great significance because of its influence on coal behavior during mining, preparation and utilization processes. It is well-known that Xe NMR is very poweful to estimate micro pore structures, at the same time there is a lack of information for chemical composition of micropores. In this paper, the micropores structures of some kind of coals and rapid heat treated sample of Witbank coal have been investigated using the combination between Xe and hyper-polarized Xe gas NMR spectroscopy. These combination techniques showed the estimation of average pore size for coals and also these chemical compositions because the activity of hyper-polarized Xe gas is lost with the inteaction of π electron as soon as this gas puts into aromatic regions.
