Dima Hasao: The rescue operation, supported by Sonar equipment, is ongoing as water continues to flow into the mine, hindering progress.
What is Sonar equipment?
A Sonar device, or Sound Navigation and Ranging device, uses sound waves to detect objects underwater and measure their distance, direction, and speed.
Sonar is a valuable tool for underwater tasks because GPS is ineffective underwater and cameras can have difficulty taking quality images in murky conditions.
Team Commander of the National Disaster Response Force (NDRF), inspector Roshan Kumar Singh confirmed that despite searching the vertical area and using heavy pumps to remove water, the water level has not decreased at the mining accident site.

The operation, supported by Sonar equipment, is ongoing as water continues to flow into the mine, hindering progress.
Singh said, "We have searched the vertical area but haven't been able to find anything. We are proceeding further with taking out water from the mine... The water level has only increased and not decreased. This is a joint operation of the Navy, NDRF, and Indian Army."
He also added, "The Indian Navy team, Indian army and NDRF have jointly started the search & rescue operation with the help of sonar equipment for the third day at the coal mine site."

He confirmed that the process will continue overnight, allowing a manual search to begin once the water is removed.
