Open-pit coal mining has triggered numerous ecological and environmental issues in the process of meeting energy demands. Underground coal gasification technology for slope coal provides a new approach for clean and efficient coal utilization, and its collaborative development with ecological restoration is of great significance. This paper deeply analyzes the principles of underground coal gasification technology for slope coal and ecological restoration methods, explores the collaborative development model of the two, including the combination of gasification and reclamation, vegetation restoration, etc., analyzes the challenges faced, and proposes countermeasures. This research provides new ideas for the sustainable development of open-pit coal mines, helping to achieve a win-win situation for energy development and ecological protection.
