Relocatable Switchroom Design Tackles Major Water Issues

Underground water has been a major issue for Centennial Coal’s Springvale mining site, which is why the mining company contracted Ampcontrol to design, manufacture, assemble and test a relocatable switchroom along with commissioning the high voltage switchgear and Toshiba VVVF Drive System.

Ampcontrol’s Grant Waring, Senior Electrical Engineer, explained, “The Centennial Coal site has traditionally experienced major, widespread underground water issues. The Ampcontrol switchroom therefore needed to be relocatable, allowing for power supply to support the pumping of water in a range of locations.”

The switchroom is designed to run a 4kV variable frequency 700kW submersible borehole pump at a depth of 390m with an output flow rate of 100 litres per second.

As experts in hazardous area design, Ampcontrol successfully developed the switchroom with the borehole in mind and incorporated explosion protection, based on Ex p, for the borehole and pumping operations.

“This is the first in a series of switchroom designs for this site,” adds Waring, “and we are looking forward to working with the range of challenges the site will ‘throw at us’ in the future.”

Ampcontrol and Anglo American take out Innovation Award at the 2019 Mine Electrical Safety Conference

Moranbah North Mine’s Variable Speed Drive project received the Innovation Award at the 30th annual Mining Electrical Safety Association Conference earlier this month.

The technical presentation delivered by Ampcontrol’s Chief Technology Officer Tim Wylie and Shane McDowall, Anglo American’s Principal for Technology and Automation Underground Operations, outlined the development and implementation of the game changing project at the Moranbah North site.

This was the first time a high power Variable Speed Drive (VSD) has been deployed in a hazardous zone in an Australian mine, and was used on an Armoured Face Conveyor (AFC) to provide full control of starting torques on the three drive motors.

This honour was received after three years of hard work by the Ampcontrol and Anglo American project teams, who are no strangers to leading the way when it comes to innovation.

Wylie said, “We implemented a new electrical protection element that is yet to be described in Australian mining standards. As such, the project contains several industry ‘firsts’ and the electrical system reliability directly contributed to the system setting a new Australian record for monthly production.”

“The Moranbah AFC upgrade to VSD saw Ampcontrol and Anglo operate quite differently – it was more like a partnering arrangement than the standard tender and contact. In the early stages, Ampcontrol effectively worked as the ‘owner’s engineer’ to technically review and assess the available options for the variable speed drive. Technical staff travelled to China with Anglo a number of times to evaluate suppliers and drive technology,” he said.

The delivery of the system has enabled consistent AFC performance, reduced downtime and in turn delivered improved safety and productivity on site.

“The successful delivery of the system required input from almost every aspect of Ampcontrol’s business, and is a shining example of what we are capable of when we work together as a group toward a common objective. The project is something none of us could have delivered individually, but something each of us can be proud of,” said Wylie.

Ampcontrol also exhibited at the conference where we displayed our newest product offerings including Rockstarter, our multi-function outlet starter, our latest lighting range and our underground gas detection and diesel machine monitoring solutions.

Ampcontrol Singapore’s Bernie Raj moderates Engineers Australia event

Engineers Australia recently held three Thought Leadership Forums in Singapore and Hong Kong. They were part of a series that covers a range of engineering topics.

The series kicked off in Singapore with a Thought Leadership Forum on Digital Engineering on 25 April. Liak Goh from Aurecon was the keynote speaker, Ampcontrol Singapore’s Bernie Raj was the moderator for the panel discussion and ARUP’s Andrew Nelson was on the panel. Forty-five people attended the event, including His Excellency Bruce Gosper, Australian High Commissioner.

The series then moved to Hong Kong on 24 May on the topic of Waste Management and returned to Singapore on 11 June to discuss Facade.

Engineers Australia will continue to host more Thought Leadership Forums covering different topics in Malaysia, Singapore and Hong Kong. The aim of the series is to offer continuous learning opportunities that engage members and industry as well as providing opportunities for speakers to share their expertise and experience.

The next topic is on Energy. The event will take place in Singapore on 10 July and Malaysia on 11 July.

Ampcontrol India moves to new premises in Kolkata

Allenwest Ampcontrol India, the Indian branch of the Ampcontrol Group, has recently relocated to a new facility in Kolkata, leaving behind its previous premises in Bilaspur. The new facility is modern, centrally located and has already received the approval of the employees working there. Allenwest Ampcontrol India’s work focuses primarily on the mining sector and the relocation was important: Ampcontrol India needed to move closer to its customers so the business could provide improved customer support and service to the region.

“We are very excited to realise the full potential of the new facility over the coming months and have already seen a benefit to our productivity and existing relationships,” says Avinash Kumar, Sales and Service Engineer.

For those keen to visit the office in Kolkata, the address is: Allenwest Ampcontrol India Pvt Ltd, Floor 9, Victoria Park, Plot No GN 37/2, Sector 5, Salt Lake, Kolkata 700091, West Bengal.
