Abstract This design TBM model EBZ-125XK, cantilever, walking Ministry crawler roadway is widely used in ordinary mechanized mining and advanced mechanized mining when driving or similar roadway excavation. This model output torque, has a short circuit, high temperature and overload safety protection system, but also has user-friendly control system, low cut design and a high strength of the cutting head. It can be said both high efficiency, safety and adaptability. Design and development of a good performance, a wide range, high efficiency, good stability, power coal roadheader is necessary. Solve the problem of low efficiency of current mining, economic development is also important. In this thesis, EBZ-125XK do the overall design, and cutting unit used in 2K-H planetary gear optimized design. And discuss potential problems roadheader and reasonable solutions. For security, installed in inspection, maintenance, repair, and troubleshooting also done a detailed introduction.
