11.2 km Aramid Belt Proven in Underground Coal Conveying

Core Achievements

Over 104 Million Tonnes Transported

After more than eight years of continuous operation, the conveyor has transported over 104 million tonnes of coal while maintaining stable performance and reliable operation.

11.2 km Ultra-Long Aramid Conveyor Belt

BOTON supplied an 11,200 m fire-resistant aramid conveyor belt for the mine's primary underground conveyor, demonstrating the capability of lightweight aramid technology in ultra-long-distance conveying.

Lightweight Design for Greater Efficiency

Compared with conventional steel cord conveyor belts, the lightweight aramid construction helps reduce conveyor weight, lower running resistance and improve energy efficiency while maintaining high tensile strength.

Project Challenges

Long-Distance Underground Conveying

The combination of an 11.2 km belt length and high-capacity coal transport required a lightweight belt structure capable of reducing running resistance while maintaining high tensile strength and operational stability.

High Throughput, Continuous Operation

Continuous operation under heavy production loads places significant demands on splice durability, belt tracking stability and maintenance efficiency throughout the conveyor lifecycle.

Strict Underground Safety Requirements

Underground coal mining environments require conveyor belts with reliable flame-resistant and anti-static performance to support safe, uninterrupted operation.

BOTON Solution

BOTON Solution

Lightweight Aramid Reinforcement

BOTON adopted high-performance aramid reinforcement to significantly reduce belt weight while maintaining the strength required for ultra-long underground conveying. The lightweight structure helps reduce running resistance, lower energy consumption and improve conveyor efficiency.

Optimized Belt Engineering

The belt structure and splice design were specifically optimized for aramid reinforcement, achieving splice efficiencies above 90% while maintaining excellent tracking stability throughout long-distance operation.

Digital Lifecycle Management

BOTON established digital lifecycle records covering installation, inspection and maintenance history. Combined with standardized maintenance procedures, this data-driven approach supports predictive maintenance and improves long-term operational reliability.
