OUR MISSION IS BEING WITH YOU TILL BREAK THROUGH
Taiwan, Taipei-I lan expressway, Hsuehshan Tunnel, in length of 12.9 Km, the full face TBMs (Tunnel Boring Machines) with an 11.74m boring diameter will be applied for tunnel excavation for both the East Bound and West Bound main tunnels. Since, it is the first time contract specification called for the largest diameter of Telescope / Double Shielded type hard rock designed TBM in the world going to use in domestic tunnel project especially presumption that Hsuehshan main tunnels are among the most difficult TBM tunneling projects in the world in terms of adverse geology, water inrushes, tunnel size and tunnel length, therefore, pre-training of all the necessary and available information, technology and technical know-how in connection with TBM operation and maintenance to all related working crews of the TBM construction teams prior to the TBM mining operation is a great important issue. The most crucial to the success of TBM mining operation is including but not be limited to understanding and commanding ground condition, appropriate planning, normal and correct operate the TBM and its all relevant Back-up equipments and facilities, good performance of cutters inspection and maintenance works on mechanical, hydraulic and electric systems to keep high availability rate of TBM and Back-up system as well as all other supply and distribution of electricity, compressed air, water pipe line, rails and tracks systems. This paper presents our methodology and experience of TBM mining operation and maintenance in Hsuehshan main tunnels construction, with the hope to provide tunnelling and underground construction field experts for references for the future.
