Abstract: This article focuses on the application of artificial intelligence technology in the field of methane sensors and the importance of normative analysis for coal mine safety. Methane, as a flammable and explosive gas, is crucial for preventing gas explosions and ensuring the safety of miners to monitor its concentration in coal mine environments. Traditional methane monitoring methods rely on fixed sensor equipment, which often lack flexibility and intelligent processing capabilities. By combining artificial intelligence technology with methane sensors, real-time monitoring and intelligent early warning of methane concentration in coal mine environments can be achieved, significantly enhancing the safety of coal mining operations. also deeply analyzes the adaptability and improvement needs of current coal mine safety regulations after integrating AI technology, emphasizing the necessity and urgency of strengthening normative analysis in the context of new technologies. Finally, it proposes optimization suggestions for methane sensor systems based on AI technology in the field of coal mine safety, providing theoretical basis and practical guidance for building a more intelligent and safer coal production environment.
