Intelligent Characterization of Coalbed Methane Desorption Behavior Based on MATLAB GUI

In this study, a comprehensive mathematical model of the coal bed methane desorption process is established, and an interactive interface for simulating this process is developed using the Graphical User Interface (GUI) functions of MATLAB software. The callback functions corresponding to each control element are systematically programmed to ensure that all operations can be executed accurately and efficiently, enabling full interactivity between the user and the software. The resulting program combines a simple and intuitive interface with rich functionality and strong responsiveness, allowing users to perform operations conveniently while obtaining detailed results. It can rapidly generate a series of curves that represent the dynamic characteristics of the coal bed methane desorption process, providing a clear and visual representation of its progression. The software also supports precise point selection at any desired location, enabling the identification of three critical pressure points during desorption: turning pressure, starting pressure, and sensitive pressure. Based on these key points, the desorption and adsorption curve of coal bed methane can be divided into distinct stages, offering significant guidance for analyzing and optimizing practical mining operations, as well as enhancing the understanding of methane behavior in coal beds under varying pressure conditions.
