IoT sensors are anything from doctor to canary in mines

Industrial IoT is changing the shape of the mining industry and the intelligence of the devices that drive it

Published

on

The Internet of Things (IoT) has become many things in the mining industry. A canary that uses sensors to monitor underground air quality, a medic that monitors healthcare, a security guard that’s constantly on guard, and underground mobile vehicle control. It has evolved from the simple connectivity of essential sensors to devices into an ecosystem of indispensable tools and solutions that redefine how mining manages people, productivity and compliance. According to Karien Bornheim, CEO of Footprint Africa Business Solutions (FABS), IoT offers an integrated business solution that can deliver long-term, strategic benefits to the mining industry.

“To fully harness the business potential of IoT, the mining sector has to understand precisely how it can add value,” she adds. “IoT needs to be implemented across the entire value chain in order to deliver fully optimised, relevant and turnkey operational solutions. It doesn’t matter how large the project is, or how complex, what matters is that it is done in line with business strategy and with a clear focus.”

Over the past few years, mining organisations have deployed emerging technologies to help bolster flagging profits, manage increasingly weighty compliance requirements, and reduce overheads. These technologies are finding a foothold in an industry that faces far more complexities around employee wellbeing and safety than many others, and that juggles numerous moving parts to achieve output and performance on a par with competitive standards. Already, these technologies have allowed mines to fundamentally change worker safety protocols and improve working conditions. They have also provided mining companies with the ability to embed solutions into legacy platforms, allowing for sensors and IoT to pull them into a connected net that delivers results.

“The key to achieving results with any IoT or technology project is to partner with service providers, not just shove solutions into identified gaps,” says Bornheim. “You need to start in the conceptual stage and move through the pre-feasibility and bankable feasibility stages before you start the implementation. Work with trained and qualified chemical, metallurgical, mechanical, electrical, instrumentation and structural engineers that form a team led by a qualified engineering lead with experience in project management. This is the only way to ensure that every aspect of the project is aligned with the industry and its highly demanding specifications.”

Mining not only has complexities in compliance and health and safety, but the market has become saturated, difficult and mercurial. For organisations to thrive, they must find new revenue streams and innovate the ways in which they do business. This is where the data delivered by IoT sensors and devices can really transform the bottom line. If translated, analysed and used correctly, the data can provide insights that allow for the executive to make informed decisions about sites, investment and potential.


“The cross-pollination of different data sets from across different sites can help shift dynamics in plant operation and maintenance, in the execution of specific tasks, and so much more,” says Bornheim. “In addition, with sensors and connected devices and systems, mining operations can be managed intelligently to ensure the best results from equipment and people.”

The connection of the physical world to the digital is not new. Many of the applications currently being used or presented to the mining industry are not new either. What’s new is how these solutions are being implemented and the ways in which they are defined. It’s more than sticking on sensors. It’s using these sensors to streamline business across buildings, roads, vehicles, equipment, and sites. These sensors and the ways in which they are used or where they are installed can be customised to suit specific business requirements.

“With qualified electronic engineers and software experts, you can design a vast array of solutions to meet the real needs of your business,” says Bornheim. “Our engineers can programme, create, migrate and integrate embedded IoT solutions for microcontrollers, sensors, and processors. They can also develop intuitive dashboards and human-machine interfaces for IoT and machine-to-machine (M2M) devices to manage the input and output of a wide range of functionalities.”

The benefits of IoT lie in its ubiquity. It can be used in tandem with artificial intelligence or machine learning systems to enhance analytics, improve the automation of basic processes and monitor systems and equipment for faults. It can be used alongside M2M applications to enhance the results and the outcomes of the systems and their roles. And it can be used to improve collaboration and communication between man, machine and mine.

“You can use IoT platforms to visualise mission-critical data for device monitoring, remote control, alerts, security management, health and safety and healthcare,” concludes Bornheim. “The sky is genuinely the limit, especially now that the cost of sensors has come down and the intelligence of solutions and applications has gone up. From real-time insights to hands-on security and safety alerts to data that changes business direction and focus, IoT brings a myriad of benefits to the table.”
