     The Shibao block, Gulin Coal Field lies in the eastern sector of the Shibao syncline on the southern limb of the Gulin anticlinorium. Coal-bearing beds belong to the Permian Longtan Formation. Enrichment in coalbed gas is controlled by reservoir （coal beds）, wall rock properties and hydrogeological conditions as well as structure with compressioal faults other than extensional faults. The Maokou limestone has large influence on the coal bed 25 due to development of karst.
