[China's large-diameter and multi-support TBM Plateau Pearl off the line at CRCC]Recently, the domestic large-diameter multi-support TBM Plateau Pearl, jointly built by CRCC and the 14th Bureau of China Water Resources, rolled off the production line in the Changsha Second Industrial Park of China Railway Construction Heavy Industry. The equipment will be used for construction under extreme conditions such as high altitude, high ground stress, and super hard rock. The excavation diameter of TBM is 10.23 meters, the length of the whole machine is about 185 meters, the total weight is about 2300 tons, and the installed power is 8200 kilowatts. Editor/Ma Xue
In 2026, Tanzania's new mining policy officially came into effect, requiring that 20 key mining materials must be provided by local enterprises. The authorities have launched the construction of 21 manufacturing factories at the abandoned Buz Waji gold mine site, gradually replacing imports. This measure forces international suppliers to change their original pure export model, and Chinese enterprises need to turn to local production and supply through technology joint ventures and other means to cope with supply chain restructuring.Editor/Gao Xue
