Named “Tian Kun Hao”, the boat is capable of digging 6,000 cubic meters an hour, the equivalent of three standard swimming pools, from 35-meter below the water's surface. /Xinhua Photo

Tiankun’s chief designer Zhang Xiaofeng told The Beijing News that the boat can mince hard rocks and pump the silt into its pipeline, where the minced waste can be automatically conveyed to as far away as 15 kilometers from the ship. /Xinhua Photo

The construction of the vessel started in early 2016 and is expected to be completed in June next year. /Xinhua Photo
