Mining Cutting Picks – Application Cases
Client Background
The Gansu coal mine encountered extremely hard rock with a UCS of approximately 120–140 MPa.
Previously tested imported cutting tools failed completely within 20 minutes, resulting in frequent downtime of 4–5 hours per day and rapidly escalating operating costs.
Customized Solution
Xinda deployed the S135 Ultra-Wear-Resistant Cutting Picks, specifically engineered for hard-rock conditions.
Key features:
Optimized carbide grade for high-UCS rock
Reinforced ultra-wear protection layer
Proprietary brazing and material technologies
Proven stability above industry average (patented technology)
Implementation Results
Tool Consumption Reduction: Average consumption reduced from 14.2 picks/m to 3 picks/m, a reduction of ≈70%.
Efficiency Improvement: Overall excavation efficiency increased by 40%. 20 picks achieved a continuous advance of 9.1 m, significantly extending maintenance intervals.
