High Performance EBZ320M-2 Bolter Miner for Underground Mining – Integrated Roadheader With Integrated Roof Bolter for Enhanced Efficiency

Product Overview

Our High Performance EBZ320M 2 Bolter Miner (also known as Roadheader With Integrated Roof Bolter and High Speed Bolter Miner Unit) is a cutting-edge underground mining solution engineered for coal tunnels, semi-coal tunnels, and rock tunnels. This industrial-grade equipment integrates tunnel excavation and anchor bolt support into a single unit—eliminating the need for separate tunneling and bolting machinery—and delivers continuous cutting, loading, transportation, anchor hole drilling, resin pellet mixing, anchor bolt/cable installation, and nut tightening (meeting initial pre-tightening force requirements).

As a premium High Speed Bolter Miner Unit, the EBZ320M-2 is built to withstand harsh underground geological conditions, combining 320 kW high-power cutting performance with dual symmetric anchor drilling arms for unrivaled efficiency. It is the ideal choice for global mining and tunneling companies seeking to optimize productivity, safety, and operational costs in underground projects.

Intelligent Safety & Monitoring: Real-time monitoring of cutting load, drill arm pressure, and temperature prevents equipment damage; explosion-proof (ATEX certified) and emergency stop systems ensure operator safety in explosive underground environments.
High-Efficiency Dust Suppression: Reduces airborne dust by 90%+ to comply with global occupational health standards, improving operator working conditions and reducing respiratory risks.
Durable & Low-Maintenance Build: Reinforced steel frame and wear-resistant cutting picks extend lifespan by 2-3 years; modular design enables quick part replacement, cutting maintenance downtime by 60%.
Ergonomic Operator Console: Intuitive controls, adjustable seating, and digital displays minimize fatigue during long shifts, improving operational accuracy and safety.

How to Use & Operate

Pre-Operation Inspection: Fully check the High Speed Bolter Miner Unit (power supply, hydraulic system, drill arms, cutting drum, safety systems, dust suppression water levels) to ensure no leaks, damage, or malfunctions.
Machine Positioning: Maneuver the bolter miner to the tunneling face, align the cutting drum with the target area, and secure the machine to prevent movement during operation.
Cutting Operation: Start the cutting motor (adjust speed per rock hardness), initiate continuous cutting/loading/transportation of excavated material, and monitor real-time cutting load to avoid overloading.
Anchor Bolt Support: After excavating a specified tunnel section, activate dual drill arms to drill anchor holes, mix resin pellets, install anchor bolts/cables, and tighten nuts to meet pre-tightening force requirements.
Continuous Monitoring: Alternate/synchronize cutting and bolting operations; regularly check equipment temperature, hydraulic pressure, and dust levels during runtime.
Post-Operation Shutdown: Stop operations in sequence (cutting motor → drill arms → conveyor → power supply), clean debris, refill dust suppression water, and report any issues to maintenance teams.
Routine Maintenance: Conduct daily lubrication/cleaning and weekly part inspection/bolt tightening to ensure long-term reliability.

Application Scenarios

Underground Coal Mines: Ideal for full-mechanized mining faces in coal/semi-coal tunnels—timely anchor bolt support reduces roof collapse risks while boosting tunneling efficiency.
Metal Ore Mines: Suitable for iron/copper/zinc mine tunneling (soft-medium hard rock); high-power cutting ensures fast excavation with stable tunnel support.
Road/Railway Tunnels: Compact design fits confined urban/mountain tunnel spaces, eliminating the need for multiple pieces of equipment in infrastructure projects.
Hydropower/Subway Tunnels: Adapts to complex geological conditions and meets strict safety standards for critical infrastructure construction.
Emergency Tunnel Reinforcement: Rapid bolting capabilities enable quick stabilization of unstable tunnel sections, minimizing safety risks.
