National Disaster Management Authority Member, Lt General (Rtd) Syed Ata Hasnain on Sunday said that 86 meters of vertical drilling is required to reach the crust of the Uttarkashi's tunnel where 41 workers remained trapped adding that 17 meters of the drilling has already taken place.
The Indian Army has been called in at Uttarkashi's Silkyara tunnel for manual drilling at the site where 41 workers have remained trapped for the past 15 days.
The vertical drilling to rescue the trapped workers in the Silkyara tunnel, which was halted earlier today, has been resumed and the rescuers have managed to make progress over a distance of 17 metres from the hill above the tunnel.
With vertical drilling underway to further aid the rescue of the trapped workers in Silkyara tunnel, the rescuers managed to make progress over a distance of 8 metres down the ground in the last one and a half hours.
Vertical drilling, one of the several chalked-out options to bring out 41 workers who have been trapped inside the Silkyara tunnel in Uttarkashi since November 12, finally started on Sunday afternoon.

Manual drilling will start soon to cut through the debris that separates rescuers from the 41 trapped workers in the collapsed portion of the Silkyara tunnel in Uttarkashi, officials informed on Saturday.
Ground Penetrating Radar, also known as GPR, Georadar, Subsurface Interface Radar, or Geo-probing Radar, is a totally non-destructive technique to produce a cross-section profile of the subsurface without any drilling, trenching or ground disturbances.
