This technology resolves the conflict between "no land for expansion" and "mandatory capacity increase" in large bulk stockyards. It applies ultra-large-diameter high-position and ultra-long, ultra-high hollow retaining walls, compensating for uneven coal pressure through tongue-and-groove joint deformation control, achieving "zero land increase" and low-cost capacity expansion. A multi-source information fusion unattended system enables dynamic data calibration and decentralized control, achieving centimeter-level precision in stacking and reclaiming. It pioneers the world's first track-mounted coal inventory robot (error < 3 ‰ ) and builds a digital fuel management system integrating multi-source data, significantly improving inventory accuracy and security.
