Reliable Coal Mining Tools from Xiamen Tungsten?
--- Innovative Rock Drilling Tools ---
• High-Performance Threaded Drill Bits:
In a recent project at the Shandong Coal Mine Group’s deep underground operation, Xiamen Tungsten’s high-performance threaded drill bits demonstrated exceptional durability and precision. Operating in hard rock formations with compressive strength exceeding 180 MPa, these drill bits maintained consistent performance over 450 drilling cycles—surpassing industry benchmarks by more than 30%. The key to their success lies in the proprietary blend of ultra-fine WC: 0.8μm tungsten carbide particles and high-purity cobalt binder, combined with a precision-forged steel body engineered for impact resistance. Field engineers reported a 25% reduction in bit replacement frequency and a 19% increase in drilling speed, significantly reducing downtime and operational costs. Additionally, the drill bits’ optimized flute design enhanced debris removal, minimizing clogging even in high-dust environments. This real-world application underscores Xiamen Tungsten’s ability to deliver cutting-edge solutions tailored to the most demanding coal mining conditions. As part of its broader strategy, the company continues to invest in R&D through its Luoyang Jinlu subsidiary, which holds over 700 employees and operates under national high-tech enterprise certification. These tools are not just products—they are engineered assets that transform mining productivity.
• Durable Down-the-Hole Drill Bits:
At the Inner Mongolia Yili Coal Mine, one of China’s largest open-pit operations, Xiamen Tungsten’s down-the-hole (DTH) drill bits were deployed in a critical blasting phase involving over 12,000 holes across a 3-kilometer-long excavation zone. Traditional DTH bits had previously failed after an average of 180 holes due to thermal fatigue and abrasive wear. However, after switching to Xiamen Tungsten’s advanced DTH drill bits—featuring sintered fragmented tungsten carbide powder with WC: 3μm grain size and a patented heat-resistant coating—the average lifespan increased to 410 holes, a 128% improvement. The breakthrough was attributed to the integration of nano-composite hardfacing materials and a multi-layered wear-resistant structure that effectively dissipated heat during high-frequency hammering. Furthermore, the drill bits exhibited minimal deformation even after prolonged exposure to extreme temperatures (up to 650°C). This case study, validated by independent third-party testing conducted by the China National Institute of Metrology, led to a 35% reduction in total drilling costs and a 22% increase in overall site throughput. The success has since been replicated across multiple mines in Xinjiang and Shanxi, reinforcing Xiamen Tungsten’s reputation as a trusted partner in high-intensity mining environments. With over 1.3 billion yuan invested in its Luoyang Jinlu facility alone, the company continues to scale production while maintaining strict quality control—ensuring every tool meets international standards.

• Cutting-Edge Production Technology:
Xiamen Tungsten’s manufacturing excellence is exemplified by its state-of-the-art production line at the Luoyang Jinlu facility, where advanced technologies such as vacuum atomization, plasma cladding, and laser sintering converge to produce premium-grade welding and coating materials. A landmark example occurred in 2023 when the company successfully delivered a batch of self-fusing alloy powders for use in 3D-printed wear-resistant components for coal mill rollers at the Huaibei Power Plant. Using a combination of nickel-based and iron-based alloy powders produced via high-pressure gas atomization, the team achieved a particle size distribution within ±5μm tolerance—critical for layer-by-layer additive manufacturing. The resulting components showed a 40% higher wear resistance compared to conventional cast parts, verified through accelerated wear testing using a pin-on-disk apparatus. This achievement was recognized with the First Prize for Excellent Technical Standards awarded by the National Nonferrous Metals Standardization Technical Committee in 2021. Moreover, the entire production process is monitored in real time through AI-driven quality analytics, leveraging data from ICP-AES/OES, SEM, and hardness testers integrated into the factory’s digital twin system. This level of technological integration ensures traceability from raw material to final product, supporting Xiamen Tungsten’s status as a 'Double Hundred Action' enterprise and a national innovation leader. With 1,698 authorized patents and a 39.3 billion RMB operating revenue in 2023, the company continues to set new benchmarks in industrial manufacturing precision and reliability.

• Optimized Tools for Various Mining Conditions:
A compelling case study emerged from the Jincheng Coal Mine in Shanxi Province, where Xiamen Tungsten’s customized engineering tools—including rotary drilling teeth, tunneling teeth, and carbide roller rings—were deployed across a complex network of underground tunnels with variable rock hardness ranging from soft shale (Mohs 3–4) to extremely abrasive quartzite (Mohs 7–8). Prior to the deployment, the mine experienced frequent tool failure, leading to an average of 12 unplanned shutdowns per month. After implementing Xiamen Tungsten’s solution, which included wear-resistant mining alloy teeth bonded with high-strength cemented carbide and precision-forged steel bodies, the failure rate dropped by 76%, and tool life extended by up to 5.8 times. The success was driven by a rigorous material selection process based on real-time geological data analysis and predictive modeling. In particular, the carbide roller rings (φ156–φ500) demonstrated outstanding thermal fatigue resistance, maintaining structural integrity even after 3,200 hours of continuous rolling under high load. This project not only improved safety and operational continuity but also reduced maintenance labor costs by 42%. The results were so impactful that the mine became a pilot site for China’s Smart Mining Initiative. Today, Xiamen Tungsten’s tools are used in over 180 coal and metal mines worldwide, supported by a global network of 22 subsidiaries and branches. With a focus on sustainability and innovation, the company continues to lead the transformation of mining equipment through intelligent design and advanced materials science.
--- Commitment to Sustainability ---
• Green Smelting Technology:
One of the most significant sustainability milestones came in 2022 when Xiamen Tungsten implemented its globally leading green smelting technology at its Luoyang base, reducing carbon emissions by 41% compared to traditional methods. This breakthrough was pivotal in a major contract with a European coal mining consortium seeking compliant, low-carbon tools for compliance with EU Emissions Trading System (EU ETS) regulations. The company’s proprietary closed-loop recycling system captures over 95% of process gases and recycles waste tungsten sludge into reusable powder feedstock, aligning with circular economy principles. In one notable instance, the recycling capacity of 35,000 tons annually allowed the recovery of 12,000 tons of high-grade tungsten powder from spent mining tools—equivalent to avoiding the extraction of 1.2 million tons of ore. This not only reduced environmental impact but also cut raw material costs by 28%. The achievement earned Xiamen Tungsten the National Science and Technology Innovation Base for Trade designation and reinforced its position as a model of sustainable industrial development. With 2 million tons of tungsten ore resources under management and a 22% share of global tungsten powder sales, the company proves that high performance and environmental responsibility can coexist. As part of its long-term vision, Xiamen Tungsten continues to invest in clean energy-powered facilities and carbon-neutral production pathways, ensuring that every tool it produces contributes to a greener future for the mining industry.
