Reduced per-ton electricity consumption by 16.3%, yielding over 2.2 million RMB in annual power bill savings.
Extended the conveyor belt's operational life to 8–9 years through an ultra-high impact-resistant structure that acts like industrial body armor.
Embedded RFID technology paired with non-destructive AI diagnostic systems to fully merge physical asset monitoring with digital workflows.
The Zhuanlongwan Coal Mine, operated by Yan Energy under Shandong Energy Group, is a modern mega-mine with an annual capacity exceeding 10 million tons. Its original 200-meter-deep underground main haulage system relied on traditional steel cord flame-retardant belts, which suffered from excessive dead weight, high energy draws, and labor-intensive joint maintenance.
By the end of 2024, the mine partnered with BOTON's subsidiary, Shandong New Balong, to carry out a comprehensive intelligent transformation. Releasing 547.2 tons of legacy steel cord belting, the project deployed a lightweight, high-performance digital aramid conveyor system, spearheading a green, smart transition for underground mining logistics.
The massive weight of the legacy steel cord belt (72 kg/m) forced the drive motors to operate under high baseload conditions, bloating power bills.
Falling coal lumps and sharp tramp material frequently caused hidden tears in the top cover or catastrophic belt slitting, threatening operations.
Relying on manual inspections across miles of underground tunnels made pinpointing early defect locations extremely slow, risking costly unplanned shutdowns.
BOTON swapped out the heavy steel infrastructure for an advanced aramid woven fabric core. By taking advantage of aramid's high strength-to-weight ratio, the upgrade cut the conveyor's dead weight by 25%, drastically reducing the structural inertia and operating power required by the drive motors.
To withstand severe material impacts at transfer points, the belt features an advanced dual-layer weft yarn design that diffuses perpendicular impact forces horizontally across the matrix. Paired with a specialized anti-tear mesh encapsulated along the belt edges, this creates an industrial "body-armor" protective envelope that prevents puncture propagation.
BOTON embedded heavy-duty RFID tracking chips into the belt structure at precise 20-meter intervals, assigning the system a continuous digital coordinate map. This array works alongside an automated, non-destructive AI scanning system that monitors splice movement and core condition 24/7, turning traditional manual tracking into automated predictive maintenance.
