Uncertainty about the safety and survival of eight people – two engineers, two technicians and four workers – trapped in 14 km in the Srisailam left bank canal (SLBC) tunnel near Domalapenta in the Telangana Nagarkurnool district even in 60 hours The latter (8pm on Monday) is also unknown.
Despite all the hard work and full-day efforts of the Joint Rescue Team, including personnel from the Central, State and other agencies, they were unable to overcome the last 150 meters of obstacles due to constant new difficulties. Some members were able to reach the Tunnel Boring Machine (TBM), now covered with debris, including mud, but were unable to use the gadgets they brought in to track the whereabouts of the trapped people.

It is said that the 12-meter TBM head section is divided into two parts, with a “safe container” on the head for sheltering workers in emergencies. It is not clear whether eight people entered the container because the roof slab fell and the seepage of water became dense.
The teams of L&T, IIT Madras and Uttarakhand handled the Skyra tunnel crash in 2023, joining the rescue operation with electronic gadgets in addition to Army, Navy, NDRF, SDRF and NHIDCL personnel.

According to officials from the Telangana irrigation department, agencies involved in the rescue operation reviewed the condition of the tail of the TBM and explored the possibility of debris removal on the TBM due to accidents, due to pre-made cured cement on the roof – concrete The slab fell off the roof and caused the accident caused by the accident, and it fell.
It turns out that trampling on the last 150 meters is a difficult task, as sleds accumulate on the tunnel floor and the infiltration of water is said to have made the rescue team’s mission difficult. “The length of the tunnel 13.8 kilometers from the mouth is covered with 6-7 feet of height mud on the floor,” said a senior official who coordinated the operation.

To remove debris and soil and to sustain dehydration, the rescue team must make further progress. It is a conveyor belt used to use the material excavated by the TBM (soil mixed with stones) as a mix, and is used by the rescue team as a ramp to go beyond the last point until the locomotive runs.
