摘　　要：Objective More than 60%of China＇s coalbed methane（CBM）resources are distributed in medium-high rank coalbearing basins.Exploration practices have confirmed that the medium-high rank CBM enrichment and high yield zones are mainly distributed in the slope areas of coal basins and are significantly jointly controlled by gas content and permeability of coal seams.Objective More than 60%of China＇s coalbed methane（CBM）resources are distributed in medium-high rank coalbearing basins.Exploration practices have confirmed that the medium-high rank CBM enrichment and high yield zones are mainly distributed in the slope areas of coal basins and are significantly jointly controlled by gas content and permeability of coal seams.
