Conquering Extreme High-Temperature & Sandy Conditions: Xinhau XH-2200 Drill Helps Tanzanian Gold Mine Meet 97% Core Recovery Standard.

I. Basic Order Information

● Product Involved: XH-2200 Fully Hydraulic Wireline Core Drill (equipped with Weichai 250 engine, Kawasaki double tandem piston pump)

● Cooperative Client Country: Tanzania

● Client Type: End Client (A leading local enterprise engaged in gold mining and exploration)

● Client Contact Channel: 2024 China International Mining Congress (Tianjin) (The client visited live equipment demonstrations and expressed preliminary cooperation intent)

● Products & Quantity Purchased: 3 XH-2200 Fully Hydraulic Wireline Core Drills (including matching drill tools and mud circulation system)

● Total Project Value: 1.85 Million USD

II. End-to-End Order Process (Challenges & Solutions)

● Initial Requirement Alignment (November 2024)

Core Client Requirements: Adaptation to the "high temperature (42°C+), dusty, deep hole (450m)" exploration conditions in northern Tanzanian gold mines, requiring a core recovery rate ≥95%, and the equipment needed to pass local mining safety certification (TBS certification).

● Mid-Phase Technical Challenge Resolution (December 2024 - January 2025)

Challenge 1: High-Temperature & Dust Protection: High dust concentration in Tanzanian mines easily clogs traditional hydraulic systems.

Solution: Customized a "Three-Stage Dust Filtration System" (air intake + hydraulic oil tank + electrical cabinet). Upgraded the surface coating to a fluorocarbon abrasion-resistant coating (salt spray test rating: 1500 hours). Conducted a 72-hour continuous no-load operation test in a simulated 45°C laboratory environment to verify stability.

Challenge 2: TBS Certification Adaptation: The client required compliance with Tanzanian mining safety standards, necessitating additions like an "emergency brake dual protection system" and "anti-fall guardrails for the operating platform."

Solution: The R&D team completed drawing modifications within 15 days. The quality inspection team simultaneously issued test reports compliant with TBS standards, assisting the client with the certification application.

● Production & Delivery Assurance (February - March 2025)

The client required production completion within 30 days (to commence exploration before the rainy season). We achieved this via "Modular Parallel Production" (simultaneous processing of hydraulic and mast modules), finishing in 28 days. Delivery used "solid wood crates + waterproof membrane"双层包装, with 2 technical engineers accompanying the shipment to prevent dust ingress during sea transit.

● After-Sales Maintenance & Client Feedback (April 2025 - Present)

After-Sales Actions: Upon arrival, technical engineers were stationed on-site for 15 days for assembly, operator training (training 10 local technicians), and establishing a "24/7 Remote Response Mechanism" (resolving 3 minor faults via video guidance).

Client Testimonial: "The drill operated continuously for 10 hours in 42°C heat without failure, achieving a 97% core recovery rate, far exceeding expectations! The dust-proof design and TBS certification significantly enhance our competitiveness in local mining projects. We plan to purchase 2 additional units."
