Underground Mining Services

We ensure efficient, safe and compliant longwall relocations with customised relocation management packages and on-site support. 

We understand the logistical and resource-heavy requirements associated with longwall relocations. Our specialists work alongside on-site staff to manage the electrical requirements of the relocation, ensuring your electrical components are returned to service efficiently and in compliance. 

Our on-site service teams deliver carefully planned longwall electrical project management, complete with thorough inspection documentation, ensuring adherence to the highest occupational health & safety standards and AS/NZS 2290 statutory requirements. This provides your leading underground mining contractors with the assurance and expertise that their equipment will operate reliably and as intended, optimising uptime and safety.

Works required are identified through the inspection process and implemented across the longwall production period. Depending on your longwall's capabilities and the required work, upgrades and repairs can be completed on-site or in our workshops in QLD and NSW.

Our onsite technicians can install, or provide assistance to help your team install, a range of electrical equipment, including:

• Electrical supply systems (substation, DCB, CME supplies) 

• Longwall electrical systems 

• Monorail electrical systems 

• Lighting systems 

• Gas monitoring systems 

• Conveyor signal line systems. 

• Network systems (copper and fibre) 

• Pump system commissioning. 

Our specialist team can provide engineering, onsite and workshop support services to keep underground conveyors and fixed equipment working efficiently, including inspections, maintenance, repairs and audits. 

As the OEM, we can provide specialist support for Ampcontrol electronic relays and electronic systems, including iMAC, VoiceCom, Gasguard and OCS. 

We can also manage equipment introduction to the site, return to project planning, power-on commissioning, and periodic maintenance.

As established specialists in explosion-protected equipment, we can conduct pre-overhaul audits and AS/NZS 4871 audits of equipment and installations.

Periodic inspections can be undertaken using documentation from the company’s mine owners and/or client sites. These inspections include:    

• Inspection of enclosure internals for signs of heating, loose connections and components, moisture, insulation deterioration, etc 

• Inspection of enclosure externals for damage to labelling and signage, windows, seals, operators' interfaces, etc 

• Statutory testing of protection functions for your business operations

• Protection audits and setting updates

Through system tests, we can ensure correct operation of critical electronic systems. System tests can include: 

• Gas detection system testing 

• iMAC and VoiceCom system testing 

• SIL system testing (functionality only) 

• Review of fault logs/capture of data. 

Safety systems with SIL ratings require periodic proof and validation testing. We can complete this testing in our workshops or on site underground as required, including:

• Time-phased proof testing 

• Fault diagnostics and repairs (including re-validation). 

Ampcontrol has certified AS/NZS 3800 workshops in NSW and QLD, purpose-built for the development, repair, overhaul and modification of flameproof equipment designed for use in explosive atmospheres. Our team of engineers can also provide SIL certification for flameproof enclosures in Australia and worldwide.

Our innovative team of engineering experts develop world-leading electrical and electronic solutions for a variety of applications, with safety and reliability at the forefront of their designs. Their expertise is backed not only by their proven experience but also by their precision measurements, testing and analytical equipment and instrumentation.
