Tunnel collapsed due to negligence; army called
  • The Himachal Pradesh government finally called the army after the Bilaspur tunnel collapsed 2 days ago.
  • Earth moving excavators which were being used in rescue attempts were damaged by debris, and a heavy-duty hydraulic drill was called from Jaipur to continue operations.
  • Meanwhile, workers revealed that a 4m long crack which had appeared on the roof of the tunnel could have caused the collapse.

Rescuers make contact with workers
  • After 5 days of rescue attempts, authorities established contact with two of the workers- Satish Tomar and Mani Ram.
  • This was achieved after engineers managed to drill a 47 m deep vertical shaft, 4 inches in diameter allowing authorities to supply the workers with food and water.
  • A remote camera and a microphone were also lowered to facilitate communication.
  • Hirdey Ram was not found.

Technical glitches slowing rescue operation
  • The heavy-duty hydraulic drill, which was being used to drill a shaft wide enough to evacuate the workers, encountered several glitches.
  • The rig broke down on the 18th and was subsequently repaired.
  • With just 1 metre of thick rock left to be drilled, the rig malfunctioned again.
  • Furthermore, rainwater accumulation slowed progress and a high-power pump had to be installed to counter it.

The obstacles

Fact
Do you know?

While the heavy-duty rig was drilling a vertical shaft, there were on-going operations to excavate the mouth of the collapsed tunnel. However, this horizontal route was blocked by more than 60 metres of debris, making the operation futile.
