Abstract: The study ained at evaluating the development potential of coalbed methane( CBM)resouces in Songhe Minefeld,.westen Guzhou. Based on the demonstration project of CBM exploration and development in Songhe Mine Fie d,the paper discussed the characterstios of CBlM ocurence and reservoirforming and researched the recoverablity of CBlM resouces by analogy metod.adsoption isotherm cunves method and numeical simulaton method.The research showed that CBM rsources were mainly hosted in the muti le lov permeatiliy and thin to medium thck cal seam groups of Longtan Formation coal measure. itsgeothermal gradient was 3.0~5.5 ℃C/ hm,pressure c.eficient was 1.08~ 1.40.gas content was 6.45 ~20.99 m3/'t and gas saturation was greater than70%.The resevoir had the characteristicsof high temperature,overpressure,high gas content and high to super gas saturation;yhich were beneficial o the CBM ground development.The CBiMl mineable co8fficients were 40%~ 53%,64.4%～69.9 % and 43.6%～44.3% respectvely by analogy method adsoption isotherm curves method and numeical Slmulaton method. The comprehensive analysis results showed tht the CBlMl mineable coeficient was45%～ 50% in reseach area which showed better CBM recoverability characterstic .
