Drilling in the collapsed part of the tunnel had to be stopped again on Friday night to rescue the workers, in another blow to rescue efforts.

A 46.8 meter section of 800 mm wide steel pipe was pushed into the drilled path ahead of some brief drilling on Friday. The length of the collapsed part of the tunnel is about 60 meters. To supply food and other essential items to the workers, a six-inch wide tube has been extended to 57 meters.

On Saturday morning, a large drilling machine was moved to the hill above the tunnel, where experts have identified the two lowest elevations for vertical drilling. The Border Roads Organization (BRO) has already built a 1.5 km long road to the top of the tunnel, as vertical drilling has been under consideration for some time.

International tunneling expert Arnold Dix had said a few days ago that vertical drilling is a more time-consuming and complex option, requiring greater precision and caution due to the relatively narrow space at the top of the tunnel.

The relatives of the workers trapped in the tunnel are gradually losing patience due to repeated interruptions in drilling by the machine and not getting the desired progress. Virendra Kisku, brother of Devendra Kisku, resident of Banka, Bihar, is among the workers trapped in the tunnel.

A part of the tunnel being built on the Chardham Yatra route had collapsed on November 12, due to which the workers working in it were trapped on the other side of the debris. Since then, various agencies are carrying out rescue operations on a war footing to get them out.

Food, medicines and other essential items are being sent to the workers through six-inch wide pipes. A communication system has been established using pipes and relatives of the workers have spoken to them. An endoscopic camera has also been inserted into the tunnel through this pipe, through which rescue workers are able to see the situation inside.
