Abstract: We use software to simulate and restore the settlement history of enrichment region, and study Fukang coalbed methane accumulation region according to correlation factors of coalbed methane accumulation combining with sample observation and experiment of coal reservoir. The study results show that the coalbed methane accumulation in Fukang Mining Area is a unique model which is extruded inclined thick seam coalbed methane accumulation. The coalbed methane accumulation in Fukang Mining Area is mainly affected by extrusion force and hydro-geological conditions. Extrusion effect makes deep coalbed methane content high and hydro-geological condition plays a blocking role in the formation of coalbed methane.
