Efforts were underway on Sunday to build an access road at the top of the hill above Silkyara tunnel for initiating vertical drilling to reach 41 workers trapped for seven days, with authorities hopeful that a platform to drill the hole might be ready by this afternoon.
Larger diameter pipes have also been inserted up to a length of 42 metres through the debris this morning to provide enough food and other essentials to the trapped workers, a control room set up at the site said.
Work on building the road began towards Saturday evening with personnel of the Border Roads Organisation (BRO) on the job, an official at the spot said.
