U170 Pick: Wear-resistant, durable, and high single-tooth extraction capacity.

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

In the coal mining industry, "efficiency" is an unavoidable core topic—progress a little faster, downtime a little less, and overall benefits can be significantly boosted. As the "teeth" of tunneling and coal mining equipment, the performance of picks directly affects the mining pace. The fact that Duerbot picks stand out in helping coal mines improve efficiency is no accident; there are several solid "secrets" behind it. Today, let’s dive into them.

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

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

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

Secret 2: Duerbot picks adapt 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 have many interbedded impurities and complex structures. If picks aren’t specifically designed for these conditions, they either can’t cut effectively or are easily damaged, making efficiency improvements impossible.

Duerbot 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" rock; for soft coal seams, the chip removal groove design 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 jams due to poor chip removal. After switching to Duerbot’s adapted picks, jams decreased, and coal production per shift increased by 30%. Workers noted that "operations became much smoother."

Secret 3: Duerbot picks come with on-site service, promptly resolving usage issues

Coal mining operations are fast-paced, and if pick-related issues arise 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 Duerbot picks.

Whenever a coal mine has needs, Duerbot engineers make special trips to the site—when picks are first put into use, they help check installation and adjust cutting parameters; during subsequent operations, any questions are quickly addressed via phone or video calls, with on-site visits arranged if necessary. When a coal mine in Shandong first started using Duerbot picks, workers weren’t fully familiar with operational details. An engineer arrived the same day, identified abnormal wear due to incorrect cutting angles, and provided a solution. With such on-site support, coal mines can focus more on mining progress without worrying about pick-related issues.

For coal mines, choosing the right picks means choosing the right "efficiency partner." Duerbot picks don’t rely on flashy marketing but instead focus on three solid aspects: wear resistance, adaptability, and service, addressing the pain points of "frequent downtime, poor adaptability, and lack of after-sales support" in coal mining. It’s precisely because of these strengths that more and more coal mines are choosing Duerbot picks, making them a "great partner" in boosting mining efficiency.
