On New Year's Eve, a diver of the navy finally reached the bottom of the 370-feet rat hole mine in Meghalaya where 15 men have been trapped for the last 19 days. But none of the trapped men were to be seen. All they saw was coal at the mouth of one lateral rat hole and mud at the bottom of the pit. Navy officers said a search will be possible only when all the water has been drained out of the network of rat holes. That operation will take time, even though the heavy-duty pumps arrived on Saturday afternoon. The first pump brought in by the Odisha fire service officials started operating this evening.
