Abstract: To systematically understand the coal reservoir characteristics in Xinji Mining Area,the used study methods involve in exploration data analysis,gas geochemical analysis,coal petrographic study,coal rank and techtonic evolution analysis.The study is focuses on CBM generation conditions,reserve evolution history and reserve conditions,as well as coal reservoir characteristics.The study results are used as foundations for further development in this area.Based on the results the pilot project adopted the hydro fracturing treatments and advanced software,resulting in largest CBM gas production and longest stable production time comparing with the same conditions' coal reservoir in other areas.
