The gypsum mine collapse in east China's Shandong province on Christmas day, has drawn widespread attention across the country, especially after 4 miners were found trapped underground. CCTV reporter explains why some of the world most advanced mining equipment, are required in the uphill rescue task.
The rescue operation is going through unprecedented challenges. In a normal drilling job, 200 meters shouldn't take any time longer than 3 days; but when there are 4 lives trapped deep down underground. It becomes a completely different scenario.
"This drill can discharge mud and water while drilling, it's one of the few equipment in the world that is capable for the rescue operation for a scale like this," said Tony Zhang, a rescuer of Bauer Maschinen Gmbh.
The rescue operation for pulling the 4 trapped miners up by a capsule, is the first of its kind in China; and due to the complicated geological layers underground, only advanced equipment, like this large drill from Germany, can do the job.
The greatest progress made in the past few days, is that we've once again established contact with the 4 miners. This is made possible, after the drilling of the 2nd small diameter shaft to send down supplies. People sighed in relief, when the camera captured the miners’ movements.
"Make sure to have some nutritional drinks first and move the lenses around so we can see what it is like in the tunnel," said a rescuer of Pingyi County, Shandong Province.
Based on the information given by the miners, the situation in the underground tunnels is very complicated, and they've experienced some collapses. The amount of space they have now is very limited.
While no one knows when the drilling can finally make a successful break through, people across the country are fixated on the fate of the trapped miners, and those 13 who are still unaccounted for.
