[Shenjiang No. 1 participated in the construction of the deepest submarine tunnel] On August 23, China's self-developed subsea tunnel shield machine rolled off the assembly line in Changsha, Hunan. The equipment shield machine has an excavation diameter of 13.42 meters, a total length of 130 meters, and a total weight of 3,800 tons. It will participate in the construction of China's deepest submarine tunnel-the Zhujiangkou Tunnel of the Shenzhen-Jiangmen Railway. The Pearl River Mouth Tunnel is a key control project of the Deep River Railway. "Shenjiang No. 1" crosses the section with a total length of 3590 meters. The entire line is tunneled downhill for a long distance and passes through the Pearl River estuary. The engineering geological conditions are extremely complicated. Editor/Xu Shengpeng

• [The first vertical large-scale mineral model in southern Xinjiang landed in Kashgar]
• At the 16th Xinjiang Kashgar Central Asia South Asia Commodity Fair held recently, the first vertical mineral resource model in southern Xinjiang that targets multiple mineral types and full exploration scenarios, the Congling Zhixun AI intelligent mineral exploration model, was launched. It is reported that the Congling Zhixun large model deeply integrates decades of field survey data from China's first line geological exploration, constructs high-quality datasets and sample libraries, and fills the industry gap of specialized mineral large models for intelligent exploration of multiple mineral types in the southern Xinjiang Central Asia metallogenic belt.

• Recently, as the last set of wires steadily arrived at the traction field, the Gansu to Zhejiang ± 800 kV high-voltage direct current transmission project, Gansu Section 4, achieved full line connection on the 16th. This project is a key project of the national West East power transmission strategy. After completion, it can transport over 36 billion kilowatt hours of clean electricity from Gansu to Zhejiang every year, with new energy consumption accounting for over 21 billion kilowatt hours.
