What is the secret behind Duerbote picks helping to improve coal mining efficiency?

In the coal mining industry, "efficiency" is an unavoidable core topic—progressing a bit faster and reducing downtime can significantly boost overall benefits. As the "teeth" of tunneling and coal mining equipment, the performance of picks directly affects the mining pace. Duerbote picks stand out in helping coal mines improve efficiency, and this is no coincidence—there are several solid "secrets" behind it. Today, let’s delve into these.

Secret 1: Duerbote picks are wear-resistant and durable, reducing the frequency of downtime for replacement

For coal mines, nothing hampers efficiency more than frequent downtime for pick replacement. Many coal mines previously used picks that wore out quickly—either the cutting edge dulled or the pick body deformed—requiring two to three replacements per shift. Over time, effective operational hours dwindled.

Duerbote picks excel in wear resistance. The selected alloy material boasts high hardness, and the brazing process between the pick head and body has been optimized to withstand friction and impact in coal seams. A coal mine in Henan reported that using Duerbote U135 picks with Sany tunneling machines resulted in no significant wear after a full shift, eliminating the need for mid-shutdown replacements. The tunneling machine operated continuously, increasing the shift’s tunneling volume by nearly 20%. With fewer downtime issues, efficiency naturally improved.

Secret 2: Duerbote picks are adaptable to multiple working conditions, delivering stable performance even in complex environments

Coal mining conditions are never one-size-fits-all—some coal seams mix with hard rock, some are soft and prone to collapse, and others contain many impurities with complex structures. If picks aren’t specifically designed for these conditions, they either fail to cut or break easily, making efficiency improvements impossible.

Duerbote picks are finely optimized for different working conditions: for seams with high hard rock content, the alloy layer on the pick head is thickened to withstand impact and easily "crush" the rock; for soft coal seams, the design of the chip removal groove on the pick head is optimized to reduce coal dust clogging and ensure smoother cutting. A coal mine in Shanxi previously used standard picks for soft coal seams and frequently experienced machine jams due to poor chip removal. After switching to Duerbote’s adapted picks, jams decreased, and coal production per shift increased by 30%. Workers noted that "operations became much smoother."

Secret 3: Duerbote picks come with on-site services, promptly resolving usage issues

Coal mining operations are fast-paced, and if issues arise with picks without timely support, progress can easily be delayed. Many coal mines worry that "once you buy the picks, no one follows up," but this isn’t a concern with Duerbote picks.

Whenever a coal mine has needs, Duerbote engineers make special trips to the site for follow-up—when picks are first put into use, they help check installation and adjust cutting parameters; during subsequent operations, if questions arise, phone or video communication ensures quick responses, with on-site visits if necessary. When a coal mine in Shandong first started using Duerbote picks, workers weren’t fully familiar with operational details. An engineer arrived on-site the same day, identified abnormal wear due to cutting angle issues, and provided solutions. With such on-site support, coal mines no longer need to worry about pick usage issues and can focus more on mining progress.

For coal mines, choosing the right picks means choosing the right "efficiency partner." Duerbote picks don’t rely on flashy marketing but instead address the pain points of coal mining—frequent downtime, poor adaptability, and lack of after-sales support—through tangible improvements in wear resistance, adaptability, and service. It’s precisely because of this that more and more coal mines are choosing Duerbote picks, making them a "great partner" in boosting mining efficiency.
