Underground mining operations face a critical challenge: chute blockages caused by oversized rock boulders. According to mining industry reports, unplanned downtime from blockages accounts for 35% of production losses in underground mines, with manual clearing methods increasing safety risks and maintenance costs by up to $120,000 annually per site. Jinan YZH Machinery Equipment Co., Ltd., a leading Chinese manufacturer with 20+ years of expertise, offers a game-changing solution: the Electric Hydraulic Fixed Pedestal Rockbreaker Boom System. Engineered for extreme underground conditions, this system eliminates blockages efficiently, enhances safety, and reduces operational costs—making it the trusted choice for mines across 37 countries.
Traditional methods for clearing chute blockages in underground mines are fraught with challenges:
Safety Risks: Manual intervention with jackhammers or explosives exposes workers to rock falls and dust inhalation, increasing accident rates by 42% (source: International Mining Safety Institute).
Production Loss: A single blockage can halt ore flow for 2–8 hours, resulting in missed production targets of 1,500–6,000 tons daily.
High Maintenance: Frequent screen damage from oversized rocks leads to $80,000+ in annual repair costs, while diesel-powered excavators consume 6x more energy than electric alternatives.
YZH’s Electric Hydraulic Rockbreaker System addresses these pain points head-on, combining cutting-edge technology with decades of mining equipment expertise.
YZH’s BHC 500, the flagship model for underground mines, delivers unmatched reach and precision:
Working Radius: Max horizontal reach of 8,100 mm and vertical reach of 5,900 mm, covering 100% of standard chute and grid screen areas.
Rapid Blockage Clearance: Equipped with a high-frequency hydraulic hammer (140–175 bpm), it breaks F17-grade rock in 3–5 seconds—3x faster than manual methods.
360° Rotation: Full-slewing design ensures no blind spots, even in narrow underground tunnels (2.5m width minimum).
Technical Highlight: The boom arm is forged from Hardox 450 steel (wear-resistant steel), with a service life of 8,000+ hours—double the industry average.
YZH prioritizes underground safety with state-of-the-art features:
5G Remote Operation: Operators control the system from a safe distance via a tablet or joystick, reducing on-site personnel by 100% during blockage handling.
Collision Avoidance System: Sensors automatically stop the boom if it nears tunnel walls or equipment, preventing costly damage.
Explosion-Proof Design: Certified to ATEX Zone 2 standards, suitable for gassy mines (methane concentration ≤1.2%).
Customer Testimonial: “Since installing YZH’s remote-controlled rockbreaker, our underground mine has achieved 18 months of zero blockage-related accidents,” reports a gold mine in Western Australia.
Unlike diesel-powered alternatives, YZH’s electric hydraulic system offers:
Energy Savings: Electricity costs are仅 1/6 of diesel excavators, cutting annual energy bills by $48,000 for a single unit.
Zero Emissions: No exhaust fumes, improving underground air quality and complying with EU CE-PED environmental standards.
Low Noise: Operates at ≤85 dB—quieter than traditional pneumatic breakers, reducing worker fatigue.
YZH’s rockbreaker thrives where others fail:
Temperature Resistance: Functions flawlessly in -45°C (Siberian mines) to +50°C (tropical underground operations).
Dust & Moisture Protection: IP65-rated electrical components withstand high humidity and coal dust.
Minimal Maintenance: Modular design with centralized lubrication reduces downtime for servicing by 70%.
A large underground iron mine in Hebei Province faced chronic chute blockages, losing 200+ production hours yearly. After installing YZH’s BHC 500 system:
Blockage Handling Time: Reduced from 90 minutes to 12 minutes per incident.
Annual Savings: $192,000 (energy + maintenance + production gains).
ROI Achieved: In just 8 months.
Certified Quality: ISO 9001:2015 and CE certified, ensuring compliance with global mining standards.
Custom Solutions: Tailor-made boom lengths, hammer sizes, and control systems to match your mine’s unique layout.
Global Support: 24/7 technical assistance via WhatsApp (+8615610128027) and on-site service in key mining regions (Peru, Australia, Russia).
