een made in CBM exploration.However,the overall exploration level is low,besides there are great differences in the enrichment laws of deep CBM and shallow CBM.In order to find out the differences and more rational use of resources,this paper studied the source characteristics,geological conditions and preservation conditions of deep CBM and shallow CBM,analyzed the occurrence characteristics and main controlling factors of deep CBM and shallow CBM,and established the reservoir-forming model of deep CBM and shallow CBM,at last,pointed out the exploration direction.The results show that the shallow CBM has the characteristics of three gas sources replenishment,the gas sources are biogas,ther-mogenic gas and deep migration gas.Coal pore is dominated by macro pore and transitional pore.In addition to ad-sorbed gas,there is a large amount of free gas in coal seam,which accounts for 36%on average.Shallow CBM are ac-
cumulated in syncline of fold structure and hydrodynamic retention area.Deep CBM has the characteristics of two gas
