We must ensure Tunnel Boring MachinesTBM are used in all Himalayan mountain tunnel projects. There are many folds, joints, fists, & faults in geological strata of this region. Moreover the area is prone for earthquakes. Vertical shafts are compulsory at all or near the weak points to facilitate rescue ( used for ventilation). RCC tunnel lining ensures mucks are avoided. Chalthahai, chalthahai attitude of senior engineers and cost emphasised projects leading to substandard specifications like, go ahead with blasting to do tunnel work. This attitude is the root cause of accidents and job interruptions due to the people living above the mountain(due to blast vibrations, noise, stream pollution etc). Geologist role is very important to ensure safe alignment of the tunnel. Design engineer role is very important for safe design of the tunnel. Execution engineer role is very important because he has to apply presence of mind during execution and carry out job in coordination with entire team.
