The coal-measure gas in study area is typically coal-type gas mixed with a small amount of oil-type gas acoording to the δ 13 C 2. And the evolution of coal-measure gas has been dominated by thermogenic origin. Combining the gas concentrations and isotope, the vertical and lateral migration process of coal-measure gas has been observed.The cases, which were originally collected for a new CMRS classification for coal measures, have been used in the paper to test the performance of the NGI system. Changes in the NGI classification are proposed so as to include horizontal stratification, joint orientation or unfavourable horizontal stress and some special geological features. ...
