South African miner Gold Fields is the latest company seeking to bring together the brightest minds in order to solve one of its toughest questions.

The company has launched the Ore-X Innovation Challenge, a contest to develop an image processing algorithm to classify material in a gold mine as high, medium or low grade or, or waste.

The contest carries a first prize of A$10,000 (US$7,100), second prize of A$1,500 and third prize A$500.

The challenge will consist of two parts--processing the image to find features, and then estimating the overall grade. Contestants who submit their estimated grade and percentages and will be scored based on the number of correct answers.

The top five ranked submissions will then submit their algorithm, which will be assessed on accuracy of the results, including subjective criteria such as the classified images, code quality, and ease of integration.

The Ore-X Innovation Challenge will provide contestants with a dataset approximately 1.2GB in size, containing 218 images, each approximately 12 megapixels.  

Submissions are currently open and will close on September 25. Winners will be announced October 9.

Growing trend

Crowdsourcing initiatives have become a growing trend among companies in the mining industry. In June, Canadian miner Integra Gold Corp launched the Gold Rush Challenge, an innovative contest that allowed online prospectors to analyze and interpret 70 years of data to come up with a plan of making a major gold discovery.  The reward was $1 million.

"By giving the public access to this data, Integra hopes to tap into the collective brainpower of thousands of participants and save itself years of time and resources to identify high-potential exploration targets we likely wouldn't even know exist," said Integra Gold CEO Stephen de Jong.

Goldcorp held a similar challenge in 2000 that attracted over 1,600 participants and helped the company find roughly $6 billion in gold.

Mining smart with the latest tech isn’t just for the majors. Smart Mining Technology can unlock the future for more connected and productive operations

Digital technology has become a key enabler of margin improvement and an enhancer of competitiveness in the mining sector. Although the majority of the top mining businesses have already started their digital journey in some capacity, many of the smaller players are lagging behind when it comes to digital transformation. 

Smart Mining with IoT

Recent analysis by Allied Market Research, which estimates that the global smart mining industry is projected to reach $24bn by 2027, relays fears that those that don't join the big players in the digital uptake of solutions like IoT, will be left behind.

“As a traditionally risk-averse industry, many mining sector stakeholders struggle to invest in new technologies without a guaranteed return on investment (ROI),” explains Matthew Margetts, Director of Sales & Marketing at Smarter Technologies – suppliers of IoT solutions to the UK’s Ministry of Defence and the Royal Air Force. “Innovative miners at all levels are using new technologies to make mining operations safer, more productive, and more cost-efficient.”

Safety

Mines are often dangerous places to work, and worker health and safety are top priorities for mining operations. Smart Mining Technology keeps track of your assets and has the potential to improve mine safety in several ways: locate people, recover machinery and reduce the risk of serious injury.

Automation 

Autonomous mining vehicles have been around for nearly two decades. During this time, these vehicles have revolutionised mining by allowing humans to communicate with and control machinery remotely. In this day and age, the focus has shifted from the original autonomous mining vehicles to autonomous mining systems, which can carry out a series of integrated tasks automatically. Removing the need for humans to be on-site increases workforce safety. 

The benefits of autonomous mining functions include:

  • Improved safety
  • Decreased incidents
  • The ability to work in areas that would be too dangerous for humans 
  • Increased productivity
  • Reduced labour costs

Predictive analysis and insights 

When mining assets are connected to the Internet of Things (IoT) and a central management system, this enables operational intelligence. By analysing operational data, mining operators are better equipped to foresee and prevent any dangerous incidents from occurring. The ability to conduct predictive maintenance also means a lower risk of mechanical breakdown and failure. 

Personnel tracking 

Wearable technologies have become more advanced and non-invasive, making it easier to track the mining workforce, even deep underground and in remote locations. With real-time visibility of all staff, key workers can be located instantly. In the event of an emergency, response times and recovery rates are significantly improved. Along with improved safety, workforce tracking data can also be used to monitor staff attendance and identify where productivity can be increased.

Condition monitoring 

A series of smart IoT sensors can measure virtually anything - from pressure to humidity, temperature, air quality, gas levels, sound and more. If the conditions in a specific area change in any predefined way, instant notifications can alert teams of potential safety risks and potentially prevent incidents before they occur.  

Increase efficiency and reduced operational costs

Making mines “smart” has the effect of lowering operational costs. In a smart mine, key assets are digitised by embedding smart sensors that report data to a central system via a wireless network. Many of the same use cases of smart mining technology mentioned above not only improve mine safety, but also help to reduce operational costs. 

Wireless monitoring systems that relay real-time data lower operational costs in a number of ways:

  • Reduced reliance on paying human resources 
  • Reduced reliance on vehicles and petrol costs for data and asset collection
  • No need for expensive cabling and system maintenance operations
  • Maintaining critical assets more effectively increases return on investment

Asset visibility 

Having real-time visibility of mining assets allows you to track the location of your mining equipment when you need to use it. This is especially useful as self-driving machinery becomes more widely adopted in the industry. Instead of wasting time searching for various assets, you’ll be able to optimise productivity and profitability by streamlining your operations from your central management dashboard. 

Data collection

Automating the data gathering processes using smart technology reduces the need for time-consuming and potentially dangerous data collection. Access to real-time data is critical to optimising efficiencies and reducing costs. In contrast, by the time a worker has collected information and returned to the office, the data they have gathered is already outdated.

Maintenance and management 

With real-time data connectivity and data analytics, you can optimise your mine’s maintenance schedules and production rates dynamically. With predictive analytics enabled by smart tracking and condition monitoring, you’ll be able to quickly identify required changes to predefined maintenance schedules to keep your equipment running efficiently and safely. This too avoids potential incidents that can disrupt or halt operations for weeks or months, in turn keeping the mine running and generating profits.

 

Although there are barriers to mines adopting new technologies, these must be overcome in order for mines to remain competitive and successful in an increasingly digital age. From improving safety to enhancing productivity and efficiency, smart mines are the future of the industry.
