en.Wedoany.com Reported - On March 27, 2026, Chinese electric autonomous mining truck supplier Boonray Technology (Shanghai Boonray Intelligent Technology Co., Ltd., Boonray) signed a strategic cooperation agreement with China Railway 21st Bureau Group Co., Ltd. The two parties have been cooperating on a mining project in Inner Mongolia since 2024, and this signing marks the establishment of a comprehensive, long-term strategic synergy in the development direction of mine greening, intelligence, and unmanned operation.
China Railway 21st Bureau Group Co., Ltd. is a subsidiary of China Railway Construction Corporation (CRCC) and a central enterprise directly supervised by the State-owned Assets Supervision and Administration Commission of the State Council. The company holds multiple special-grade and first-grade qualifications for general contracting in fields such as railways, highways, municipal works, construction, and mining. Its business covers engineering contracting, survey and design, real estate development, material trading, equipment manufacturing, etc., with an annual construction capacity exceeding 50 billion RMB (approximately 7.26 billion USD). Public information shows that the company has participated in key project constructions in regions such as Gansu Jiugang, Xinjiang Zhundong, and Inner Mongolia Ordos, accumulating rich experience in mining engineering, railway dedicated lines, and coal collection and transportation. In recent years, China Railway 21st Bureau has continuously promoted mine intelligent construction, deploying unmanned electric mining trucks in the Shengli East No. 2 Mine Area in Inner Mongolia (under Shengli Energy Company, a subsidiary of China Energy Investment Group), achieving unmanned operation in the mine transportation process.
Boonray Technology is one of China's electric autonomous mining truck suppliers, recognized as a national-level specialized, sophisticated, distinctive, and innovative "Little Giant" enterprise and a national high-tech enterprise. It is dedicated to providing global mining with zero-carbon unmanned mine overall solutions. The company has successively received strategic investments from industrial capital and institutions such as State Power Investment Corporation (SPIC), BYD, Tonly Heavy Industries, and BOC International Investment, accumulating over 1 billion RMB in financing in the primary market by 2025. Currently, Boonray's vehicle fleet has been deployed in more than 30 mining projects nationwide, covering raw materials for construction such as coal, metals, limestone for cement, and other industrial minerals. Its "Boonray Electric Bull" series of pure electric autonomous mining trucks includes models such as the 105-ton capacity "Electric Bull 105" and the 145-ton capacity "Electric Bull 145". Equipped with core technologies such as the fully self-developed iDrive autonomous driving system, vehicle controller, intelligent electric drive system, and intelligent battery swap stations, they achieve fully unmanned operation in the mine transportation process. The company has accumulated over 60 million kilometers of operational mileage, with its autonomous electric fleet having stably operated for nearly four years, maintaining a record of zero safety incidents.
The two parties will focus on the development direction of mine greening, intelligence, and unmanned operation. They will integrate the resource advantages of China Railway 21st Bureau in mine engineering general contracting and domestic/overseas project development with the technical capabilities of Boonray Technology in L4 autonomous driving, electric mining trucks, unmanned battery swapping, and intelligent dispatching, to jointly build safer, more efficient, and greener mines.
