On February 9, Yanbao Energy’s project Continuous Intelligent Coal Mining Technology with Bucket Wheel in Open-pit Mines in Extremely Cold Regions was successfully selected as a national pilot project for intelligent technology upgrade and application in coal mines. This marked a breakthrough for the Company in intelligent coal mining in extremely cold environments.
Targeting special conditions of open-pit mining in extremely cold regions, the project built a complete operation chain for continuous coal mining with bucket wheel, consisting of bucket wheel excavators, transfer conveyors and working face belt conveyors. It optimized the route of the coal conveying system, realized seamless connection between new and old systems, and achieved coordinated and efficient operation of the continuous process with the existing discontinuous process and semi-continuous process. In addition, the project broke through core technologies, precisely matched equipment parameters, developed a special compact bucket wheel excavator with large cutting force for extremely cold regions, forming an integrated solution for design, manufacturing, assembly, commissioning and operation of core equipment for continuous mining. It also developed control technology and a management platform for the continuous system, promoting intelligent decision-making and precise control in mining, and achieving labor reduction and efficient production.
As a typical demonstration of smart open-pit mining in extremely cold regions, the project effectively addressed challenges including low efficiency and poor equipment adaptability for coal mining under extremely cold environments. Relying on technological advantages including pure electric drive and intelligent collaboration, it enhanced production efficiency, reduced mining costs, and facilitated the green transformation from oil to electricity, providing strong support for the coal industry to foster new quality productive forces and ensure energy supply security.
