Compared with other rocks, coal is easily affected by such environment conditions as temperature, pressure, and tectonic *** macromolecular structural evolution could induce changes in the nanopore structure of Deformed Coals, which is the most important reservoir space for Coalbed *** data show that gas outburst has a very close relationship with tectonic deformation because it often occurs in shear zones where deformed coals are widely *** amounts of outburst gas are usually much higher than the maximum adsorptions that are supposed to be in coal,which means that excess coalbed methane may exist in deformed coals.

As the important un-conventional energy resource, the development and utilization of shale gas play a strategic role in the ***, the very fine porous structures in gas shale pose large *** of the high sensitivity of nuclear magnetic resonance (NMR) to local environments at the atomic and molecular level, compared with conventional characterization methods for porous media such as MIP and BET,NMR possesses greater advantages and ***, the traditional NMR Relaxation Porometer (NMRT) lacks fingerprint significance due to its inherent flows(Fig.1).In this study, using 1H as the probe, we have spared no efforts in developing comprehensive NMR methods to characterize nano-porous structure in shale, which willbe efficient, robust, cost-saving, portable and easily operative.
