Then I went to the other side. They hugged us, lifted us. And thanked us for taking them out," Munna Qureshi told reporters on Tuesday evening after coming out of a Himalayan tunnel in the northern Indian state of Uttarakhand. He was among a dozen or so workers who cleared the last stretch of debris by hand to help free 41 workers who had been trapped in the under-construction 4.5km (3-mile) Silkyar.tunnel for more than 16 days. A landslide had caused a portion of the tunnel - part of the $1.5bn (£1.19bn), 890km-long flagship Char Dham project to connect key Hindu pilgrim sites - to cave in on 12 November. Mr Qureshi, 29, has been described by officials and media alike as a "rat-hole" miner and hailed as "the hero of the rescue operation". He and his mates crawled into the 800m pipe and cleared the 12m debris of the last stretch in under 18 hours, according to Lt-Gen Syed Ata Hasnain, a senior official overseeing the operation. They were "confident and nonchalant" about the work they were doing, willing to "go in with anything... no special tools as such", he told NDTV. Miners employing the hazardous "rat hole" technique engage in the excavation of narrow, purpose-built pits in the ground, large enough for one person to go down and extract coal. The nimble miners - usually slim boys and men - carry loads of wet coal in baskets up on wooden slats flanking the walls of these mines, mostly found in the north-eastern state of Meghalaya. The Supreme Court banned it in 2014, but it continues illegally. In this photograph taken on January 31, 2013, a miner slowly carries a heavy load of wet coal on a basket hundreds of feet up on wooden slats that brace the sides of a deep coal mine shaft near Rimbay village in the Indian northeastern state of Meghalaya.

"Once we went down, there was hardly any light streaming in from above," a man who left his job at a 'rat-hole' mine in Meghalaya told the BBC in 2019. "The mines I had worked in earlier were only about 30ft (9m) deep. But this was far more dangerous. It was nearly 400ft deep." In Uttarakhand, engineers believe, labelling the rescue workers who entered the pipe as "rat-hole miners" may not be entirely accurate. They call them manual excavators, who go into tight spaces to clean and carry out repairs - most of the so-called 'rat-hole" miners at the tunnel worked in cities fixing water and sewer pipes. Skilled tunnelling mechanics and manual excavators had to be deployed at least thrice during the operation to clear blockages in the tunnel. The first time it happened was last week when the main auger drilling machine broke down inside the tunnel, engineers said.
