iii. Tunnel support systems cannot be accomplished by sticking only to one approach. Tunnel support stability is not only an engineering concept but also a safety issue and hence that needs to be earnestly investigated. In so doing, catastrophes during tunnel construction process can be minimized as much as possible. Conclusion This paper has looked into the general principles of exploration of tunnel boring machines and general considerations of tunnel construction . Cutter heads are the major determinants of the power of a TBM. For the success of tunnel construction, the stability of the surrounding rock mass during the construction process has been especially highlighted. The study also looked at the geotechnical factors that would influence the tunnel support stability . Tunnel stability is a very important aspect to consider during a tunnel construction project. The stability of a tunn el is majorly influenced by loads on the roof of the tunnel , in the side walls and in the underground of the background .
