Client Background

The Zacatecas silver mine is located in the state of Zacatecas in north-central Mexico. It is one of the world's renowned high-grade silver production bases, with an annual ore processing capacity of approximately 2 million tons. The mine adopts underground mechanized mining methods, featuring steep ramps and scattered working faces, which impose extremely strict requirements on equipment safety and availability.

Challenges Faced

High Altitude and Complex Geology: The mine is situated on a plateau at approximately 2,500 meters above sea level. The thin air significantly affects diesel engine power output. At the same time, the ore body surrounding rock is highly jointed, requiring extensive ground support work with high risk.

Safety Compliance Requirements: Mexican mining regulators enforce strict standards for braking systems, Rollover Protective Structure (ROPS), and exhaust emissions on underground equipment. All equipment must carry internationally recognized safety certifications.

After-Sales Response: As a large multinational mining company, the client requires equipment suppliers to have a well-established service network and parts support capability across Latin America to avoid substantial losses from downtime.

Beijun Solution

Shandong Beijun Group provided a customized equipment package tailored to the mine's high-altitude, steep-gradient operating conditions:

Primary Haulage Equipment: UQ-35 Underground Dump Truck
   Powered by the Yuchai engine + Fast transmission + Hande axle "golden powertrain chain," with ECU program optimization for high-altitude conditions to ensure stable power output. Equipped with Beijun's proprietary wet brake system, effectively handling long-distance downhill haulage under full load. Overall vehicle stability improved by approximately 30 percent compared to the industry baseline.

Personnel Transport Equipment: RU-18 Trackless Personnel Carrier
   Designed to transport a 20-person crew underground simultaneously. Equipped with FOPS/ROPS certified cabin, fully ensuring miner safety during commuting through complex tunnels.

Ground Support Equipment: Wet Shotcrete Machine and Scaling Jumbo
   To address the challenge of poor surrounding rock stability, the solution provided high-efficiency wet shotcrete machines for primary ground support, paired with scaling jumbos to replace manual scaling operations, significantly improving safety factors.

Implementation Results

Availability Guarantee: Beijun UQ series underground dump trucks have been proven in actual operation at the Zacatecas mine, achieving an availability rate of over 95 percent. The client has already placed a second order for additional equipment.

Service Response: Leveraging Beijun Group's branch offices and parts warehousing network in Latin American countries including Chile and Peru, core parts can reach the mine within 72 hours. The solution also includes localized technical training and "4-hour rapid response" on-site support.

Cost Optimization: Compared to similar European and American equipment, Beijun products offer significant procurement cost advantages while meeting EU CE certification and ISO system standards. Fuel consumption performance is better than the industry average, effectively reducing cost per tonne of ore transported.

Client Testimonial

"Beijun's equipment is robust and durable, performing satisfactorily under Zacatecas' high-altitude conditions. The wet brake system gives us full confidence during downhill haulage operations. As a Chinese manufacturer capable of providing rapid after-sales response across Latin America, Beijun's service capability has exceeded our expectations." – Equipment Procurement Manager, Zacatecas Silver Mine
