In a coal mining project in Shanxi, the shearer picks, as critical consumable components, directly impact mining efficiency and cost control. Recently, a coal mine encountered challenges during construction: the imported brand of picks they were using frequently experienced broken shank issues, which not only affected the construction progress but also increased additional maintenance costs and potential safety risks.

Challenge: Frequent Broken Shank Issues

This coal mining project is located in a hard rock area of Shanxi, where the complex geological conditions place extremely high demands on the wear resistance and impact resistance of the picks. At the beginning of the project, the construction team chose an imported brand of picks, hoping to ensure smooth construction through its brand reputation. However, as the construction progressed, problems gradually emerged: the picks frequently broke at the shank under high-intensity operations, causing equipment downtime and severely impacting the construction schedule.

Solution: Duerbote Alloy Bean Picks

Faced with this challenge, the project team began searching for solutions. After a series of market research and technical comparisons, they decided to try Duerbote alloy bean picks. Duerbote picks are renowned for their high-strength alloy materials and precision heat treatment processes. This material not only offers high hardness but also excellent toughness and wear resistance, making it highly suitable for hard rock conditions.

Performance in Action: Significant Improvement

After switching to Duerbote picks, the project team quickly found that the broken shank issues that had plagued them were effectively resolved. Duerbote picks demonstrated excellent wear resistance and impact resistance in hard rock conditions, maintaining stability even under high-intensity operations, reducing replacement frequency, and lowering maintenance costs. Additionally, the service life of Duerbote picks was longer than that of the previous imported brand, further proving their high cost-effectiveness.

Customer Feedback: Increased Satisfaction

The project manager stated: "The performance of Duerbote picks exceeded our expectations. Under the same conditions, their durability and stability far surpassed other brands, significantly reducing equipment downtime and maintenance costs. We have made multiple repeat purchases and will continue to collaborate with Duerbote in the future."

Technical Analysis: Combination of Materials and Processes

The outstanding performance of Duerbote picks in hard rock conditions is primarily due to the high-strength alloy materials and advanced heat treatment processes used. This material ensures high hardness while maintaining excellent toughness, effectively resisting impact and wear. Additionally, Duerbote employs precision heat treatment processes during production, further enhancing the wear resistance and service life of the picks.

Key to Improving Construction Efficiency

This successful application not only demonstrates the exceptional performance of Duerbote picks in hard rock tunneling but also provides valuable reference for other coal mining projects facing similar challenges. Choosing the right picks is crucial for improving construction efficiency, reducing costs, and ensuring safety. With their excellent performance and high cost-effectiveness, Duerbote picks have become an ideal choice for the mining industry.
