  ABSTRACT: Hydrological conditions play a key role in the occurrence and accumulation of coalbed methane. In order to further study the hydrogeology and deep coalbed methane enrichment law, the analysis of hydrogeological conditions, formation water type, mineralization degree and groundwater parameters shows that: 1) High formation water metamorphic coefficient, low sodium chloride coefficient, low desulfurization coefficient and low magnesium calcium coefficient of common formation water in coalbed methane high gas content area; 2) The influence of groundwater dynamic conditions on coalbed methane enrichment is reflected in two aspects: first, it can dissolve coalbed methane in coal reservoirs, resulting in coalbed methane escape; second, it can block the gas and play a role in preservation; 3) The gas content increases with the increase of mineralization as a whole, and decreases with the increase of water head. This achievement provides certain theoretical support for the later development of coalbed methane.
