Telangana tunnel collapse Day 10: Location of eight people unknown, search operation to take 2-3 days to locate them: CM Revanth Reddy

The team leaders of key rescue agencies involved in tracing the eight persons trapped in the Srisailam Left Bank Canal (SLBC) tunnel since February 22 morning have informed Chief Minister A. Revanth Reddy that debris removal in the last 20 metres of the tunnel is most problematic and challenging.

Since that portion of the tunnel, particularly its left flank and roof, is still loose and not stable with seepage of water in high volume going on, the government could consider alternative tunnel roots from the 13.45 km from the mouth to link it with the original path where the stable strata is available. It could be done by taking up two tunnels dug from either side with 5-metre diameter each to handle the designed discharge capacity of 4,000 cusecs.
