"Earth's Crust 1 has a low failure rate of 2.5 percent and the highest it dug was 286 meters a day," said Sun Youhong, R & D director, deputy headmaster of Jilin University. "All these achievements fully reflect the capability of China in independent research and development of drilling rigs."

The researchers from Jilin University also solved the challenges of having extreme temperature within the deep earth and taking rock samples from complex environment.
