[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 intelligentization of Shanxi coal mines will be basically achieved by 2027]
• Shanxi recently issued the "Implementation Plan for Accelerating Energy Green and Low Carbon Transformation and Development", aiming to promote the construction of the energy system and high-quality economic development. The plan proposes to focus on building intelligent green coal mines with a capacity of over 1.2 million tons per year, accelerate resource allocation and transfer, and exit inefficient production capacity. At the same time, it is required that production coal mines that meet the conditions by 2027 achieve basic intelligence, cultivate artificial intelligence application scenarios, continuously improve safety assurance levels, and fully guarantee the stable supply of national electricity coal.
