Rescue Workers Continue Clearing Debris
Rescue teams are working tirelessly to clear slush, metal, and other debris from the last 50-70 meters of the 14-kilometer-long tunnel. The operation remains challenging due to the heavy accumulation of debris.
At D1, one of the suspected locations identified by the Human Remains Detection Dog (HRDD) squad from Kerala and Ground Probing Radar (GPR), debris has piled up to a height of nine meters. Officials suspect human remains in this area.
Miners and Specialised Teams Engaged in Excavation

- 30 HP capacity liquid ring vacuum pump
- Vacuum tank-equipped machine
- Hydraulically powered autonomous robot
The vacuum tank mechanism is capable of transporting 620 cubic meters of mud per hour via a conveyor belt to expedite debris removal.
