In the heart of Krakow, Poland, researchers at the AGH University of Krakow are tackling a challenge that resonates deeply with the mining and construction industries: the durability of conical picks used in mechanical rock cutting. Led by Łukasz Bołoz, a team has developed a robust method for quantitatively assessing the wear rates of these crucial tools, potentially revolutionizing how companies select and invest in cutting equipment.
Conical picks are indispensable in both mining and construction, capable of processing a wide range of rock types. However, in demanding conditions like metal ore mining, their lifespan is often frustratingly short. “The service life of conical picks is significantly limited in highly demanding conditions,” Bołoz explains. “This drives the need for methods to extend their operational lifespan and improve their durability.”
The team’s research, published in the journal *Production Engineering Archives* (known in English as *Archives of Production Engineering*), introduces a dedicated laboratory test rig and a comprehensive procedure for evaluating the wear rates of conical picks. This method allows for direct comparison of products from different manufacturers, enabling companies to make more informed, cost-effective decisions.
The significance of this research extends beyond mere technical innovation. It has the potential to reshape tender procedures and procurement strategies in the energy sector. By providing a standardized way to assess wear rates, the method ensures that companies can select the most durable and cost-efficient picks available. “The developed procedure allows the selection of picks to be optimized by adjusting the weighting of price-related factors according to current financial and operational requirements,” Bołoz notes.
The research has already been validated through practical applications, including projects commissioned by Polish coal companies and independent research initiatives. The team has explored various formulas for determining mass wear rates and discussed alternative approaches to calculating performance indicators, ensuring the robustness of their methodology.
One of the most compelling aspects of this research is its potential to drive future developments in the field. By providing a clear, quantitative method for assessing tool durability, it encourages manufacturers to innovate and improve their products. This could lead to the development of new materials or coatings that enhance the longevity of conical picks, benefiting the entire industry.
In two case studies, the team demonstrated the applicability of their method. The first involved tender procedures conducted by a Polish coal company, while the second focused on identifying materials or coatings that could improve the durability of conical picks compared to commercial solutions. These real-world applications underscore the practical value of the research.
As the energy sector continues to evolve, the need for efficient and durable tools becomes ever more critical. The work of Łukasz Bołoz and his team at the AGH University of Krakow offers a promising path forward, providing a tool for assessing wear rates that could shape the future of mechanical rock cutting. Their research not only addresses a pressing industry need but also sets a new standard for tool performance evaluation, paving the way for innovation and improvement in the years to come.
