Abstract: In order to reveal the rich integration of geological characteristics of coalbed methane (CBM),using theoretical analysis method from the law of coalbed methane rich integration hidden index,the degree of enrichment,rich integration form three aspects,geological characteristics of coalbed methane rich integration are analyzed.For evaluation of coalbed methane rich integration hidden potential,through the geological formation and characteristics of coal seam and the research of evaluation index,selection of coal seam thickness,coal bed porosity and permeability of coal seam,coal rank,coal seam gas content,etc.as main evaluation parameters of coalbed methane.The research shows that the thickness of the coal seam thickness of single well of coalbed methane total more than 10m,single layer thickness is greater than 0.6 m,coal bed porosity radius is about 4 to 8 nm,permeability of coal seam is greater than 2×10^-3μm²,levels of coal for the coal fracture development,and coal seam gas content is about 4.25m³/t can be defined as CBM potential evaluation standard.
