An approach to grading coalbed methane resources in China for the purpose of implementing a differential production subsidy

Abstract The heterogeneity of coalbed methane (CBM) resources was not taken into account when the current indiscriminate subsidy policy was developed. In it, limited subsidy funds are given first to high-quality resources and even to subsidize profitable projects. Thus, the policy has had less than...
