Steps Involved in the Process of Tunneling and Boring

PROBE DRILLING

Probe drilling is first among the Steps Involved in the Process of Tunneling and Boring done to find out the best method of drilling for that site. In these various samples are taken by different drilling methods and then the most suitable one is chosen for the job.

GROUTING

Grouting is the second of seven steps involved in the process of tunneling and boring. It is the process of providing additional support to the drilled mine. It is carried out with the help of a liquid called grout. It helps in achieving a smooth surface.

EXCAVATION

Excavation is the process of digging and recording of artifacts at an archaeological site. It is performed by experts and it is an important step of seven steps involved in the process of tunneling and boring since it is necessary to know the archaeological importance of a site before digging.

SUPPORTING

Once the initial mining process is completed the tunnel now requires supports so that the further steps can be carried out. Nowadays support is provided by injecting pipes or sometimes building it before carrying out the further steps.

COATING

Material is coated by polishing, painting to prevent wear and tear and to protect it from corrosion. It is extremely important for the corrosive metals to protect them from corrosion

DRAINING

Draining is the process to remove the water that is accumulated there. This process becomes extremely important for those sites where the water level is high.

Ventilation

This is the most important step of the seven steps involved in the process of tunneling and boring for the safety of the site workers. A proper exit route is created for the exit of hazardous gas from the tunnel.
