Underground Mining Services
We offer a catalogue of services that ensure the longevity and performance of underground electrical equipment and systems.
Timely maintenance and support
In advancing the energy sector, we’ve established a series of high-calibre services to support underground mining.
We pride ourselves on delivering complete end-to-end solutions for our customers, and our accompanying services reflect this commitment. From installation, commissioning, inspection and testing through to AS/NZS 3800 overhauls, upgrades and repairs, we ensure the longevity and performance of all our customers’ underground electrical equipment and longwall systems.
Our services can be tailored for longwall operations and relocations, as well as conveyor and fixed equipment, allowing us to meet more advanced electrical needs. Delivered by a team of onsite professionals, each service is supported with specialised engineering resources, a service fleet of vehicles and equipment and strategically positioned workshops to ensure timely maintenance and assistance.

AZ/NZS 3800 Overhauls
Ampcontrol has certified AS/NZS 3800 workshops in NSW and QLD, purpose-built for the repair, overhaul and modification of flameproof equipment designed for use in explosive atmospheres. Our team of engineers can provide SIL verification for flameproof enclosures.
Engineering Design
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 by the latest in precision measurement, testing and analytical equipment and instrumentation.
End of Block Upgrades and Repairs
Works required are identified through the inspection process and implemented across the longwall production period. Depending on the works required, upgrade and repairs can be completed onsite in situ or in our workshops in QLD and NSW.

Longwall Support and Relocations
We ensure efficient, safe and compliant longwall relocations with customised relocation management packages and onsite support.
We understand the logistical and resource heavy requirements associated with longwall relocations. Our specialists work alongside your onsite staff to manage the electrical requirements of the relocation, ensuring your electrical components are put back in service in an efficient and compliant manner.
Our onsite service teams provide time phased longwall electrical maintenance plans and corresponding inspection documentation to ensure the highest safety standards are maintained and compliant to the statutory requirements of AS 2290, providing peace of mind your equipment will run as it is supposed to, when it’s supposed to.
