Congratulations to our company on the successful hard rock mine testing of the 20UA rock drill.
2025-12-18

The independently developed 20UA rock drill has passed rigorous tests in f14–f16 hard rock formations after 12 months and 2,300 drilling hours. Maintaining a stable drilling speed of 2.2 m/min and a single drill rod cycle of 1.5 minutes, it showed zero quality issues except for routine maintenance, with all performance indicators meeting preset standards. Notably, its in-house manufactured impact piston lasted 1,600 impact hours before replacement, reaching advanced domestic and international levels.
