Navy deploys more ROVs to explore mines

SHILLONG: The Indian Navy Tuesday deployed five more unmanned remotely operated vehicles to survey the nearby abandoned mines and ascertain if they are linked with the main shaft, where the 15 miners got trapped on December 13 last.
As of Tuesday, two out of four mines that may be connected with the main shaft have been sanitised and explorations by underwater remotely operated vehicles (ROV) were also undertaken at night, operation spokesperson R Susngi said.
The ROV exploration, however, could not be continued as the diameter of the rat-holes inside the shafts are too small and further exploration will continue as and when feasible, Susngi said.
On Monday, the Navy had sent an ROV down the 370-feet-deep main shaft to determine visibility at the base, but it got stuck. This unmanned vehicle was put into service Monday to determine the visibility deep down at the bottom of the mine shaft and in case if there was any sign of the trapped diggers.
Coal India Ltd, which ran their pump in an abandoned mine Tuesday for 8 hours, drained nearly 11 lakh litres of water, while the Odisha Fire Service pumped out 5.4 lakh litres using two pumps from two other adjacent abandoned shafts.
East Jaintia Hills district Deputy Commissioner F M Dopth, who is also the chairman of the district disaster management authority, informed the state government that it might take 30 days or up to two months to pump out the water from about 20 shafts in the area.
Based on the expertise of the local coal miners and endorsed by experts from the North Eastern Coal Fields, Dopth quoted Rs 4.61 crore as the amount required for procurement of materials and manpower to pump the water out of the mines. Tuesday was the 27th day of the Meghalaya mine disaster which also had drawn attention of the Supreme Court. (PTI)
