Based on the achievements of previous research, the authors improved the model of multiple superposed coal bed methane (CBM) bearing system and developed a computer software system with language C⁺⁺ in Microsoft Visual Studio 2008.After successful testing in Windows platform, the authors chose an example of Shuigonghe Syncline, in Zhina Coal Field of Guizhou Province for simulation. The results showed that the CBM reservoir formation evolution process of CBM was well reflected and the software was developed successfully.
