Case Study: Stanwell’s Meandu Mine

Rajant Corporation has partnered with Acubis Technologies to deliver the Peregrine and Hawk wireless BreadCrumb nodes to Stanwell’s Meandu Mine, Australia.

The challenge: Stanwell’s Meandu Mine was struggling with the ever-evolving data and application requirements of its operation network. The network supports CCTV, access control, in-vehicle management, and autonomous haulage and needed additional throughput that could be provided by the Peregrine and Hawk BreadCrumbs. The network conditions are harsh. with large, towering ridges around the mines with multiple applications running at once.

Stanwell's Meandu Mine

Stanwell owns Tarong power stations, one of Queensland’s largest electricity generating sites, with coal coming from the Meandu Mine. This means there is high dependency on sustained operations and critical infrastructure security.

Rajant Peregrine and Hawk nodes are robust and secure. They have the ability to grow with the capacity needs for future applications, delivering a cost-saving solution to Stanwell’s thermal power production.

Integrating these highly scalable BreadCrumbs into the network allowed all applications to run continuously and at peak performance. The nodes maximised the use of the fleet management system, enabled telemetry and high precision GPS technologies, and provided connectivity for CCTV, environmental, and control systems.

Rajant Case Study – Phosphate Mining Company

 

Phosphate mining company, Mosaic, needed a way to optimise production and reduce its environmental footprint at its Four Corners mining facility.

Mosaic’s Four Corners Florida mine covers 60,000 acres, and is the largest and most complex centre of operation for the organisation. Multiple, critical applications must always be running simultaneously to maximise efficiency. The mine runs 24 hours a day, 365 days a year, with the phosphate then shipped off to major agricultural centres across the world, and powers a significant chunk of the economic activity in North America.

The mesh network that was being used ran at about 900 MHz, the point-to-point radios had very slow bandwidth and were positioned almost a mile away from each other, which resulted in frequent network interruptions, and in turn, slowed down production.

Four Corners was dependent on draglines, which are constantly moving and come with a high capital cost. One way to minimise costs and error is to set up ruggedized cameras to actively monitor the dragline operations, however, the low-bandwidth network meant only two cameras were able to be supported, which made it difficult to pinpoint issues.

Rajant’s solution

In order to improve the communication network, Mosaic partnered with Rapid Systems, a wireless solution provider, who introduced Rajant’s Kinetic Mesh technology to update the infrastructure.

“Mosaic’s Four Corners is a complex environment because of its large size and infrastructure. It was imperative that we install a resilient wireless network that could support multiple mobile applications without a break,” said Dustin Jurman, CEO of Rapid Systems.

Kinetic Mesh networks are comprised of a number of individual nodes, rather than a static infrastructure. This enables all devices, and the entire network, to be mobile, which is essential in mining facilities where vehicles an equipment are constantly moving.

The mesh network enables multiple radio frequencies between any nodes, which continuously transmits data in real-time via the best possible traffic path.

There is no central control node, which means there is no single point of failure. Routes are constantly monitored for performance, if there is an issue the signal will be instantly rerouted to the next best possible path. This allows the network to adapt to node locations, local interference and congestion.

Once set up, this new solution allowed a number of new applications to be deployed, including company intranet, VoIP phones and video monitoring systems.

“Using Rajant’s wireless network, we have implemented highly functioning command centres with detailed dashboards that allow us to monitor even our mobile gear, such as draglines and pit cars, ensuring that nothing ever sits idle, to maximize productivity.” “Ivan and his team are continually innovating and improving their processes, which makes Mosaic’s Four Corners a unique mining site. The opportunities to add value are endless,” Jurman said.

Most importantly for mining operations, Rajant’s Kinetic Mesh has allowed Mosaic to create and install new applications to boost their commitment to safety. The information that can now be transferred via the network allows operators to continuously track and monitor key performance indicators. Nodes positioned in strategic locations can track mines and important machinery giving them a transparent view of the operation. This improves productivity and also reduces the risk of failures and safety issues.

Circular polarised antennas in mining industries

Circular polarisation has opened a new door in underground mining and tunnelling communication. It allows antenna signal to travel through tunnels, avoiding potential obstructions, and creating a reliable signal throughout.

The radio waves transmitted with this type of polarisation are not constrained to just linear or horizontal situations when bouncing off the walls. They create a mirror effect, making a cylinder shape as they travel down the tunnel. The radio waves can radiate around obstacles, enabling them to adapt well in various tunnel dimensions. Circular polarisation prevents these waves from fading, which they are likely to do with vertical and horizontal polarisation, and allows those working in these conditions to maintain constant communication and situational awareness.

The Poynting MinePoynt HELI antennas have been designed for use in mining and tunnelling industries, with patented circular polarisation technology.

There’s been numerous tests performed in mines over the past few years to examine the benefits of using these antennas. One of these tests involved a large train moving through a tunnel. Significant signal loss was expected, but was unchanged due to the way the signal propagated around the obstacle.

Within these tunnels there are lots of potential issues that can affect the strength of the signal, including:

 

The HELI antennas have been designed to overcome these obstructions and maintain a reliable signal within these harsh environments.

The MinePoynt HELI range has been established for several years, and is deployed in a number of mines and tunnels across Europe, Australia, Africa, USA, Canada and more. The range offers both dual-band 2.4/5GHz and LTE/5G antennas in a smaller size enclosure compared to their bigger brothers, the popular HELI-3, HELI-4 and HELI- 8. The antennas offer medium to high gain, whilst providing the smallest possible installation height for mounting on tunnel roofs and walls.
