Joint teams from multiple agencies participating in the rescue operationEight people have been found in the Srisailam Left Bank Canal (SLBC) tunnel since Saturday morning, and concluded that any obstacle trying to cross the last 50 meters is completely filled with dirt and debrisTunnel Boring Machines (TBMs) are at risk for the life rescue team.

Even the Navy Special Forces divers, Joint Marcos, was unable to wader through the mud, which was said to be due to the increasing intensity of seepage. A fresh cavity is formed at the exact site of the tunnel collapse, which mixes more soil with water and is evaluated as the cause of the snow sludge discharge.
Navy drivers can wade 70% water and 30% mud
navyDivers can wade in muddy water, which includes 70% water and 30% mud. However, in the case of SLBC, the percentage of mud is found to be more than 70%, which will make it difficult for divers to pass through it with heavy utensils (equipment).
The top priority for dehydration
Therefore, this is at the review meeting chaired by Deputy Chief Minister M. Bhatti Vikramarka, Ministers N. Uttam Kumar Reddy, Jupally Krishna Rao and Komatireddy Venkat Reddy and Arvind Kumar (Jaiprakash Associates Sideby) should give priority to the first priority The entrance of the SLBC tunnel to facilitate the progress of the rescue team and reach the exact location where two engineers, two technicians and four workers were trapped.

At the meeting, representatives from all central, state and other rescue agencies, as well as representatives from both working agencies, explained how it is becoming increasingly difficult to cover the last mile, even as the uncertainty about the chances of survival are reduced. Many places cover trapped people every hour.
It’s now more than 80 hours (until 4pm on Tuesday), and eight people are still not tracked despite the hard work of the rescue agency. Official sources said they are making new arrangements to improve the lighting of the tunnel as it becomes darker as more mud accumulates. Even the conveyor belt used by the rescue team to cover the tunnel more than 12 kilometers from the mouth is getting weaker because it is arranged for different purposes.
Assess whether it will be in trouble further
Mud samples were also sent for geological tests to find out whether clearing debris around the TBM before the exact location of the tunnel collapse would lead to further dehydration.
