  6. Right now, a global tunnelling knowledgeable staff arrived ta the spot. Worldwide Tunnelling and Underground Area Affiliation president Arnold Dix is overseeing the operations. A robotics staff from defence analysis group DRDO has additionally reached.

  7. During the last week, a number of plans to chop by the 40-meter rock wall fell by. It had additionally backfired twice, bringing down extra rocks and rubble from the unplastered roof, extending the depth of the rock wall from round 40 to over 70 meters.
