Jingtieshan Mine, a critical iron ore base for Jiuquan Iron and Steel Group (JISCO), faced unprecedented operational hurdles in its high-altitude environment:
Harsh Climate: -25℃ winter temperatures caused hydraulic oil to gelatinize, resulting in 50% equipment startup failures
Rock Hardness: f=14 grade iron ore led to monthly jaw crusher blockages, requiring 4-6 hours of manual clearing per incident
Altitude Impact: At 3,420m above sea level, diesel-powered equipment suffered 30% power loss and frequent overheating
"Traditional blasting methods not only halted production for 60+ hours monthly but also exposed our workers to life-threatening risks," said Mr. Wang, Equipment Director at Jingtieshan Mine. "We needed a solution that could withstand our extreme conditions while improving safety and efficiency."
After 3 months of on-site investigation and engineering collaboration, YZH delivered a customized breaker system featuring:
Parameter | Value | Industry Impact |
Working Radius | 9.7m | 40% larger coverage than standard booms |
Impact Energy | 16,000 ft-lb | Breaks 1.5m³ boulders in 30 seconds |
Operating Temperature | -45℃ to 60℃ | HVX-32 low-temperature hydraulic oil system |
Control System | 5G remote + local dual-mode | Operators can monitor from 3km away |
Anti-Freeze Hydraulics: Integrated PTC heaters (5kW) and thermal insulation blanket maintain oil temperature at 45℃ in -30℃ conditions
Plateau Pressure Compensation: Variable frequency drive maintains 92% power output at 3,000m altitude
Smart Diagnostic Module: Real-time monitoring of 12 key parameters with 95% accuracy in fault prediction
The YZH solution has redefined mining efficiency at Jingtieshan:
Downtime Reduction: Crusher blockage handling time reduced from 4 hours to 20 minutes, increasing annual production by 48,000 tons
Cost Savings: Electric-driven system cut energy costs by 60% ($180,000/year) compared to diesel alternatives
Safety Enhancement: Zero manual clearing incidents, reducing accident rate from 28% to 0%
85% reduction in dust emissions (from 15mg/m³ to 2.2mg/m³)
Noise level decreased to 75dB(A), meeting ISO 11200 standards
Achieved JISCO's "Green Mine" certification for environmental performance
"YZH's system has been a game-changer for our high-altitude operations," confirmed Mr. Wang. "Their technical team's responsiveness, even during the worst winter storms, demonstrates why they're a trusted partner."
Proven Track Record: 200+ high-altitude projects worldwide, including Tibet Copper Mine (4,500m) and Russian Arctic Gold Mine (-42℃)
Certifications: ISO 9001/14001/45001, CE, and China MA mining safety certification
Rapid Support Network: Spare parts warehouses in Lanzhou, Urumqi, and Moscow ensure 48-hour on-site service
