Kola Bore Hole: The Biggest Man-Made Borehole
The project began with Uralmash-4E drilling rigs on May 24, 1970. In 1979, they upgraded to Uralmash-15000 series drilling rigs. By 1989, they had drilled the deepest hole, reaching 12,262 meters (40,230 feet). This Kola bore hole remains the deepest and biggest man-made hole.
The goal was to drill as deep as 9 miles into the Earth. However, the project was abandoned when they encountered unexpectedly high temperatures. Approximately 7.5 miles below the surface, rocks were found to be around 180 degrees Celsius. The drillers had expected high temperatures but not this extreme. Over time, the drilling machinery began to deform due to the heat. According to the researchers, the rocks at these depths were more like plastic than solid rock.
Race Of Drilling the Deepest Borehole
The Kola Bore Hole in Russia was the biggest man made borehole in the world until China stepped into this race.
Currently, Chinese engineers are drilling their deepest borehole in the oil-rich Xinjiang region. Their goal is to surpass the Biggest Man-Made Hole—the Kola Bore hole. Only time will tell whether they will succeed or not.
In conclusion, the Kola Bore hole is still the deepest man made borehole on Earth and this site has become a popular tourist attraction.

“I did my first solo trip in India with WanderOn. Initially I was sceptical about their Meghalaya-Kaziranga trip as I didn't have any prior experience with them but the team assured me that it's going to be one of the best experiences of my life.

“In Ladakh, find the perfect blend of culture, adventure, and serenity. December last year I decided that my next trip would be Ladakh but didn’t know how to go about it. I knew I wanted to travel in a group, as I had prior experiences of traveling in a group but wanted an organiser I could trust. Ladakh isn’t like other destinations wherein you need some instructions due to the high altitudes.

“After an amazing trip to Tirthan with WanderOn, I decided to go to Manali-Jispa with them and yet again, the experience was worth every penny. The place was very beautiful and the quality of service was top-notch, the itinerary was very good and the quality of transportation and stays were very good. Had an awesome time there and made some good friends as well. Lastly, our trip captains Priyasha and Rachit managed the entire trip very well and were so fun and made our trip an experience worth remembering.
