The distinctive structure and lithology of the western Sichuan Plateau offer an occurrence environment for mantle-derived gas.This paper delves into the origin of mantle-derived gas,the advanced geological prediction principles for gas emission sections,as well as detection and monitoring methods.The working strategies for gas emission sections are summarized as follows:(1)Identifying the type of mantle-derived gas and assess its hazards under varying concentrations.(2)Combining geological surveys with drilling and long-range with short-range prediction.(3)Enhancing gas detection and monitoring,as well as ventilation management for the emission of mantle-derived gas.These detection and prevention measures enable the prevention,control and mitigation of magma-derived mantle gas,thereby ensuring construction safety.The research findings can offer targeted detection and prevention strategies for tunnel construction in similar geological settings.
