It is not feasible to calculate the nation’s total CBM output simply by adding CBM drained from coal mines, with low methane content and a large variation range, to the CBM production from wells drilled on the surface. CBM production and utilization should be verified by standard measurement of commodity amount. CBM output and utilization have not reached the target as predicted in recent years. It is necessary to hold a cautious attitude towards the CBM target put forth in the 13th Five-year Plan. Sluggish CBM development resulted mainly from royalty management issues. Some national oil companies’ monopoly of the royalty is overlapped with the royalty of specialized companies and coal enterprises. Inadequate investment from enterprises also seriously impairs CBM developme
