This innovative technology combines remote-controlled robotic platforms manufactured by Brokk with specialised TEI hydraulic rock drill attachments. Consequently, it creates a versatile drilling solution for challenging underground environments.
Its compact design and robust performance have transformed previously inaccessible areas. For instance, drilling performance and techniques are well explained in understanding mining drilling results. This integration ensures that operations are both safe and efficient.
The system’s remote-control features and small footprint provide enhanced safety. In addition, the design minimises exposure to hazards in risky environments. As a result, miners benefit from increased operational flexibility and protection.
How Does the Brokk and TEI Combination Work?
The Brokk robot serves as the mobile platform with exceptional manoeuvrability, while the TEI hydraulic rock drill supplies the precision needed for underground tasks. Consequently, the combined system outperforms traditional equipment in difficult terrains.
Furthermore, the Brokk’s ability to climb steep inclines is impressive. Will Visser noted that the machine could navigate 30° slopes much more easily than conventional equipment. This feature not only increases access but also improves productivity on challenging surfaces.
In addition, the system integrates advanced digital monitoring, reflecting a wave of digital transformation in mining. Moreover, its quick-change attachment mechanism reduces downtime and makes the machine a versatile asset across varied tasks.
The hydraulic clamp mechanism is another breakthrough. It securely grips and stabilises drill rods during extension operations. Consequently, operators can drill up to 10 meters away from the machine. This innovative design ensures precise hole placement and stability even in tough rock conditions.
What Makes Brokk Drilling Solutions Unique for Narrow Vein Mining?
Narrow vein mining has always presented unique challenges. Brokk drilling solutions address these with a purpose-built design for confined spaces as narrow as 1.5 metres. Its compact size allows it to navigate tight passages where larger machines would struggle.
In addition, the machine’s ability to handle slopes up to 30° sets it apart from equipment that fails on 7-8° gradients. This capability opens up previously unapproachable deposits. Consequently, mining areas become more economically viable.
Furthermore, the machine’s remote operation limits direct human exposure to dangerous conditions. This safety aspect is reinforced when operators work from a secure distance. In related research, understanding rock deformation in mining offers useful insights into handling challenging geological conditions.
The unique design also enables controlled rock excavation without explosives. This method uses precise patterns for non-explosive rock breaking. As a result, vibration and gas emissions are minimised—a significant advantage near sensitive structures.
What Safety Benefits Do Brokk Drilling Solutions Provide?
Safety is a foremost advantage of Brokk underground drilling solutions. The remote-controlled operation removes personnel from hazardous areas, effectively reducing exposure to falling rock. Consequently, this method increases overall site safety.
Moreover, the operator can control the machine from a distance of up to 50 metres. This significant clearance decreases the risk of accidents and exposure to unstable roof conditions. Visser states, "Remote operation keeps teams safe from rock bursts and collapses."
In addition, the system’s fail-safe wireless controls and redundant safety features further enhance security. For example, if communications are interrupted, the machine will automatically shutdown. This safety feature is also detailed in a recent article on revolutionizing mining safety with ai.
The reduction in required scaffolding in maintenance areas is another benefit. Consequently, setup times are reduced and workers are not placed at height unnecessarily. This overall improvement in safety also contributes to better long-term occupational health for underground drilling teams.
Where Have Brokk Underground Drilling Solutions Been Successfully Deployed?
Brokk underground drilling solutions have been deployed in diverse mining operations across the globe. Originally developed for South African mining companies, these systems are now used worldwide in both mining and tunnelling projects.
In Western Australia, gold mines have reported stope preparation times up to 40% faster than traditional methods. Furthermore, over 100 Brokk units currently operate in Southern Africa and Australia, demonstrating the system’s adaptability in harsh conditions.
The technology is also used in European subway construction projects. In these urban environments, its compact size minimises vibration and disturbance. Consequently, infrastructure projects benefit from precise drilling and enhanced safety measures.
Moreover, a Chilean copper mine successfully integrated the system into its development cycle. The mine reduced ventilator installation time by nearly 60%, eliminating the need for manual interventions. In addition, external evidence of such innovations is discussed in an industry article on underground drilling innovations.
How Does Brokk Compare to Traditional Drilling Methods?
When comparing drilling methods, several performance metrics highlight the advantages of Brokk systems. The table below summarises a comparison between Brokk with the TEI attachment, traditional production drills, and handheld drills:
- Mobility – Brokk can negotiate 30° inclines, unlike traditional drills limited to 7-8°.
- Size – Brokk’s compact design accesses spaces as narrow as 1.5 metres.
- Drilling Cost – Although mid-range, overall project costs reduce when factoring in tunnelling and safety.
- Speed – Drilling rates are 1.5-2× faster than with handheld drills.
- Safety – Remote operation keeps the operator well away from hazards.
Traditional equipment often requires larger spaces and manual labour. Consequently, Brokk’s design is especially suited to confined and steep environments. Furthermore, the rapid setup and reduced noise levels (approximately 85 dB) make it the preferable choice for underground applications.
In addition, the efficiency of switching attachments in under 30 minutes adds operational flexibility and saves valuable production time. External industry reports, such as those on featured brokk solution, further validate these advantages.
What Types of Drilling Can Brokk Perform?
Brokk underground drilling systems are highly versatile and can perform multiple drilling functions. Its adaptability allows it to handle different tasks that would require several other pieces of equipment.
For example:
- Face drilling for precise explosive hole patterns.
- Support drilling to install rock or cable bolts in roofs and walls.
- Anchor drilling for infrastructure installations up to 10 metres away.
In addition, it can perform perforation drilling for controlled rock splitting. Consequently, this eliminates the need for traditional blasting in sensitive areas. This non-explosive method significantly reduces vibration and damage risks.
Another key application is narrow stope drilling. The machine’s six-axis articulation enables it to reach targets from multiple angles. As a result, repositioning the entire machine is unnecessary. This level of flexibility enhances productivity on confined sites.
Maintenance drilling is also improved. Brokk can access areas that traditionally require scaffold setups. Therefore, maintenance tasks are completed faster and with less risk. Each of these capabilities underscores the system’s robust design in fulfilling varied operational needs.
