Rescuers on Saturday began boring a wider and deeper hole into the tunnel at the flood-ravaged Tapovan-Vishnugad hydel project in an attempt to reach the over 30 people trapped inside for nearly a week.
“The Silt Flushing Tunnel (SFT) was punctured on Friday night itself by drilling a 75mm-diameter hole into it but now it is being widened to 300 mm so that a camera and a water flushing pipe could be inserted into the tunnel where the trapped are possibly located,” news agency PTI quoted General Manager of the NTPC project R P Ahirwal as saying.
