Abstract: The full-face TBM tunneling equipment has significant advantages in improving the efficiency of tunneling, controlling the stability of surrounding rock, and realizing automatic one-time tunneling. It exerts its advantages and applies to the construction of mine tunnels in deep complex geological conditions, which has an impact on the promotion of safe, efficient and intelligent tunneling in mines. Profound. Based on the summary and analysis of the application of TBM equipment in coal mines, combined with the engineering geological characteristics of the auxiliary transport roadway in the west of Gaojiabao coal mine of Zhengtong coal Industry in Shaanxi, this paper clearly proposes the adaptability of TBM tunneling in deep mines. Based on this, it is considered that the use of open TBM is more scientific. , And put forward targeted adaptability design of main parameters of tunneling system and adaptability technology of engineering transportation system in field application. Research shows that the use of open TBM for deep complex geological disaster mines is more flexible, and is more conducive to the prevention and control of roadway jams and other disasters, while adaptive design should mainly consider the disaster prevention and mitigation capabilities of system components such as cutter heads and shields to meet Deep complex mines have special requirements for the application of TBM equipment, such as the use of large-diameter hobs in the cutter head system to increase the tool life of hard rock roadways and increase the expansion clearance to meet the expansion needs. The research and application results can provide a certain reference basis for the research and application of TBM efficient and intelligent tunneling technology in deep mines.
