Heading and benching method is used when the tunnel section is very large and quality of rock is not very satisfactory i.e., the rock is unstable. In self supporting rocks, the top heading advance are round ahead of the bottom heading. In unstable (broken or non self supporting rocks), the bench provides platform for timber Supports to the heading.

Advantage of the Heading and Benching Method of Tunnel Construction:

Advantage in Unstable Rocks:
- The heading and benching method is considered advantageous for construction in unstable rocks.
- This method provides better stability and support in challenging geological conditions.
- The systematic excavation process helps in managing the ground conditions effectively, reducing the risk of collapses and other hazards.

In this method, it is easy to install timber support:
- The heading and benching method allows for the installation of timber support systems easily.
- Timber supports are commonly used in tunnel construction to provide temporary or permanent reinforcement to the tunnel walls.
- The ability to install timber supports efficiently can enhance the safety and stability of the tunneling operations.

Tunnelling can be continuous and work can be expedited:
- One of the key advantages of the heading and benching method is that it allows for continuous tunneling.
- The systematic approach of excavating the heading and benching sections enables a smooth workflow and expedited construction progress.
- Continuous tunneling helps in saving time and resources, making the overall construction process more efficient.

Overall, the heading and benching method offers several advantages, including enhanced stability in unstable rocks, ease of installing timber support, and the ability to expedite tunneling operations.
