摘　　要：建立煤层气解吸过程的数学模型,利用MATLAB软件中图形用户界面(Graphical User Interface,GUI)功能,完成煤层气解吸过程的界面设计,编写各控件回调函数的程序代码,实现各控件相应的功能。软件界面简单、操作方便、内容丰富、交互性好,可以快速的绘制煤层气解吸过程系列曲线,直观的表征煤层气解吸过程的特征。具有在任何位置取点的功能,及可获取煤层气解吸过程三个关键压力点(转折压力、启动压力和敏感压力),并对曲线进行划分,从而指导实际生产。The mathematical model of coal bed methane desorption process is established. The interface design of coal bed methane desorption process is completed by using the Graphical User Interface(GUI) function of MATLAB software. The program code of callback function of each control is compiled to realize the corresponding functions of each control. The software has simple interface, convenient operation, rich content and good interaction. It can quickly draw a series of curves of coal-bed methane desorption process and visually characterize the characteristics of coal-bed methane desorption process. It has the function of locating points at any location, and can obtain three key pressure points(turning pressure, starting pressure and sensitive pressure) in the desorption process of coalbed methane. Based on these three points, the desorption/adsorption curve of coalbed methane can be divided into stages, which has important guiding significance for actual mining.
