Team leader from the Navy and NDRF personnel went inside a 370-foot-deep mine, where 15 miners are trapped, to ascertain the water level inside on Sunday afternoon, officials said.

The Navy divers and their equipment arrived at the site around 1.30 pm on Sunday after which the Navy personnel started measuring the actual level of the water in the mine shaft. The 10 pumps brought by the rescue team from Odisha have been kept on standby. Meanwhile, the divers have also been kept on standby, the officials said.

The Navy wanted to ascertain the water level as their divers can operate up to 100 feet in a closed container-type situation, a district official said. Nearly 200 rescuers from various agencies are stationed at the site. Odisha Chief Fire Officer S Sethi said his team was tasked with pumping water out and they are ready for the job.
