Abstract: Underground coal gasification is the forefront technology of coal mining mode reform, which is conducive to improving the utilization rate of coal resources, reducing mining costs, safety and environmental protection and other inherent advantages.From the view point of geology, this article discusses the suitability and limitation of applying underground coal gasification technology in the Yihedabusi coal mine area of Aradabus coalfield and the selection of gasification product utilization mode in the future development process.It is concluded that although there are some limitations in the application of underground coal gasification technology from the geological perspective, as long as the appropriate underground coal gasification and the optimal gasification product utilization mode are selected, the adoption of this technology in this mining area may obtain better economic benefits.
