Six experts, comprising Indian Army Madras Engineering Group engineers and civilians, will manually drill into Uttarkashi’s Silkyara tunnel to clear debris using rat hole mining. Manual drilling is predicted to be difficult.
Officials say they will utilize rat hole mining to manually drill out pipe debris on the 16th day of Silkyara tunnel rescue efforts in Uttarkashi to speed up rescues.
Official sources report that six specialists have arrived to manually drill. They will hand remove debris from the tunnel’s 800 mm pipe. Civilians and Indian Army Madras Engineering Group engineers are on the team.
These specialized personnel will carry a drilling machine, hammer, shovel, trowel, and oxygen life support device when entering the tunnel.
Today, a plasma cutter freed the tunnel auger machine that got trapped in the pipe in horizontal drilling. Rat miners will remove 48 m of material from the tunnel opening caused by the auger equipment caught in the pipe.
Rat miners are mine workers that spend hours drilling in small tunnels like tube mines.
Rat hole mining is common in coal mining, especially in tough terrain.
“The operation is difficult. We were called from Delhi. We arrived yesterday. Our origins are Madhya Pradesh. We will work to finish drilling as quickly as feasible “A civilian professional who arrived to manually drill said.
