The solution: ORBS™ centralised blasting system

To address these challenges, Orica implemented ORBS™ (Orica Remote Blasting System) — a centralised, network-driven electronic blasting system.
ORBS™ enables mine operators to safely initiate blasts remotely via a browser-based interface, improving both control and visibility across blasting operations.

Key system capabilities

• Centralised blast initiation from a remote control location
• Browser-based user interface for simplified operation
• Integration with Blaster 3000™, i-kon™ loggers and electronic detonators
• Connectivity via LAN, Wi-Fi, LTE or fibre networks
• Scalable configuration supporting multiple blast areas simultaneously

This digital approach allows operations teams to move from fragmented, manual processes to a coordinated and streamlined blasting workflow.

System configuration

The ORBS™ deployment at Bulyanhulu included:

1. Remote operation through an internet-enabled interface
2. Connection to the mine communication network
3. Use of distributed Blaster 3000 units across underground areas
4. Hard-wired connection to i-kon™ or eDev™ detonators

This architecture enabled reliable communication across the mine while maintaining full control from a centralised location.

Measurable results 

Following implementation, Bulyanhulu achieved significant improvements in both efficiency and safety:

Improved operational efficiency

• Reduced blasting delay time by 30–45 minutes per shift
• Equivalent to ~36.5 shifts saved annually
• Simplified blasting workflows across multiple headings

Enhanced safety outcomes

• Remote initiation reduced personnel exposure to blasting risks
• Surface-based blasting control minimised exposure to fumes and ground instability

Lower infrastructure and operational costs

• Reduced reliance on harness wire (savings of approx. USD $289,080 per year)
• Faster troubleshooting with modular system structure

Data and reporting improvements

• Cloud-based SQL database for secure data storage
• Enables customised reporting and performance analysis

“ORBS at our mine has been a game-changer. One of the standout benefits is the ability to fire all blasts from a single point, which reduces the risks associated with personnel exposure and has significantly improved our operational efficiency and safety.”

Why centralised blasting matters for modern mining operations

As underground mines become more complex, the ability to digitise and centralise blasting operations is critical to:

• Improving safety outcomes
• Reducing operational variability
• Increasing productivity across simultaneous headings
• Enabling real-time decision-making

ORBS™ represents a shift towards fully connected, data-driven blasting ecosystems, aligning with industry trends in automation and digital mining.

Frequently Asked Questions

What is ORBS™ in mining?

ORBS™ (Orica Remote Blasting System) is a centralised electronic blasting system that allows operators to initiate blasts remotely using a digital interface.
 

How does ORBS™ improve safety?

ORBS™ reduces the need for personnel to be underground during blasting, minimising exposure to hazards such as fumes, rockfall and misfires.

What are the benefits of centralised blasting systems?

Centralised blasting systems improve efficiency, reduce delays, enhance control, and enable safer operations across multiple blasting locations.

Can ORBS™ be integrated into existing mining infrastructure?

Yes, ORBS™ is designed to integrate with existing communication networks and works with electronic detonators such as i-kon™ and eDev™ systems.
