Global Mining Guidelines Group welcomes Ma’aden to its membership

Global Mining Guidelines Group (GMG) has welcomed Ma’aden to its membership, the first mining company from Saudi Arabia to do so.

A fast-growing enterprise that includes a mineral portfolio of phosphate, aluminium, gold, copper and other commodities, Ma’aden continues to diversify its portfolio to encompass a wide range of industries, GMG said.

It added: “The Saudi-based company pioneered the mining industry in the region by creating a fully integrated mining value chain. This has paved the way for the development of the Saudi Arabian economy well into the future, and mining is now the third pillar of Saudi industry, a key pillar in delivering Saudi Arabia’s Vision 2030 economic diversification plans.”

Since its IPO in 2008, Ma’aden has transformed from a small gold producing company to a much larger entity. Capitalising on this momentum, the company has set ambitious goals to continue its growth trajectory by leveraging the country’s mineral deposits, increasing production rates in existing value chains, increasing exploration and adding new strategic minerals to its portfolio.

Heather Ednie, GMG’s Chief Executive Officer, said: “Ma’aden’s growth has been truly remarkable. They’ve become a leading force in the mining industry not only in the region, but globally. Collaboration remains a key component to solving many of the challenges facing the industry today and we’re certain their team of mining experts will bring a vast wealth of knowledge and experience to the Global Mining Guidelines Group.”

Saud Al-Mandil, Vice President, Digitalization & Operational Excellence at Ma’aden, said: “We are pleased to join the Global Mining Guidelines Group and contribute to the advancement of the international mining industry. As we move forward, governance and sustainable reporting will be imperative for the global industry to advance and contribute to the development of industries from food and agriculture to electric vehicles. We will continue to work with our colleagues in the industry to ensure that the mining ecosystem operates in a sustainable and efficient manner.”

In addition to owning a number of mining assets outright, Ma’aden also has a joint venture with Barrick on the Jabal Sayid copper-gold mine in Saudi Arabia (pictured).

GMG updates influential comminution circuit energy efficiency guideline

The Global Mining Guidelines Group (GMG) has brought together a project group of global subject matter experts to publish an updated version of the ‘Determining the Bond Efficiency of Industrial Grinding Circuits’ guideline.

The guideline describes the Bond method for quantifying and comparing the relative energy efficiency of most industrial comminution circuits. It’s also an effective teaching tool that can be used by junior engineers looking to understand how to apply this method, according to GMG.

This minor revision of the guideline originally published in 2016 contains additional context and clarification, GMG said.

“The Bond Work Index, published by Fred Bond in 1952, was a revolutionary theory that helped mining engineers measure rock hardness and its resistance to being crushed,” GMG said. “The harder the rock, the more energy it takes to crush it, the higher the mine’s energy bills.”

Rob McIvor, Chief Metallurgist at Metcom Technologies, said: “By relating power consumption in crushing and grinding to the feed and product size distribution, the Bond Work Index and Bond Work Index Efficiency are widely accepted throughout industry as the standard benchmarking tool essential for the design, improvement and management of comminution circuits. Metcom Technologies has continuously promoted and trained others in Bond’s methods as a required element for process improvement of mineral comminution circuits.”

Leonard Hill, Director of Metallurgy and Strategic Planning Technical Services, Freeport-McMoRan, agreed with this assessment, saying: “As we move towards defining and reducing the cost of carbon in our industry, understanding and optimising energy usage at mining operations has become a high priority. ‘Determining the Bond Efficiency of Industrial Grinding Circuits’ is a practical GMG guideline that can be used by operators and designers to evaluate the energy usage efficiency of comminution circuits. It provides a step-by-step method for collecting samples, analysing data and calculating the Bond Work Index efficiency ratio of a circuit for benchmarking and identifying process improvement opportunities.”

McIvor added: “The numerous contributions of comminution experts from around the globe has led to this rigorously vetted guide for the determination of Bond efficiency in industrial grinding circuits.”

Andrew Scott, GMG Vice-Chair Working Groups, and National Cluster Development Manager, METS Ignited, said: “GMG’s goal when facilitating these collaborative opportunities is to end up with a product that helps drive the industry forward. Our member mining companies and subject matter experts from within the mining community asked us to provide a neutral, collaborative space where they could update the previous guideline and ultimately publish a timely and educational product.”

GMG tackles mine automation safety in latest whitepaper

The Global Mining Guidelines Group (GMG) has published the System Safety for Autonomous Mining white paper as it looks to provide a comprehensive view of the need for a “system safety approach” for mining companies deploying and using autonomous systems.

It also aims to increase awareness of the system safety and its benefits by providing education and context on safety management and the system safety lifecycle, the purpose and typical contents of a safety case, the significance of human-systems integration, and factors that influence software safety management, GMG says.

The white paper intends to addresses the use of autonomous systems within the mining industry, both surface and underground. It applies to all autonomous machines and to the integration of autonomous and semi-autonomous machines with manually-operated machines, as well as to complex integrated systems of systems across the mining industry. While it was developed with a focus on autonomous systems, most of the information is general and is also relevant to manual operations, GMG says.

Explaining the paper, GMG said: “System safety is a view of safety that extends beyond the machines to consider the complete system (ie machines, human factors, and environment, and the interfaces between these). The goal of system safety is to reduce risks associated with hazards to safety. It is a planned, disciplined and systematic approach to identifying, analysing, eliminating, and controlling hazards by analysis, design and management procedures throughout a system’s lifecycle. System safety activities start in the earliest concept development stages of a project and continue through design, development, testing, operational use and disposal.”

Chirag Sathe, Project Co-Leader and Principal Mining Systems at BHP, says: “With an ever-increasing use of technology in mining, particularly in surface mining equipment, it is important to understand the overall impact of systems implementation on safety. I hope the white paper helps to increase the awareness of this important emerging topic in mine safety, not only within mining companies but also for OEMs, technology developers and implementors.”

On the role of industry collaboration both in the development and intended use of this white paper, Project Co-Leader, Gareth Topham, says: “The white paper demonstrates that the mining community continues to see the benefit in collaborating to ensure the introduction and the ongoing operation of autonomous mobile equipment is done in a safe environment. It will enable discussions between all parties to pursue opportunities to improve the level of risk to safety by addressing the topics that are contained in the paper and improving on the communication that delivers a more holistic understanding of these systems. “

On the importance of this topic from an OEM perspective, Michael Lewis, Technical Director at Komatsu, says: “The adoption of autonomous systems in mining has been growing rapidly since the first Komatsu autonomous trucks entered into production in 2008 and it’s been exciting to support our customers as they expand use of autonomous systems. Safety has always been the top priority for our industry, and as the use of autonomy grows to cover more of the mining value chain it’s important that we look at the whole system it impacts.

“I applaud the truly collaborative work between mine operators, OEMs and other GMG members in the creation of this white paper,” Lewis adds.

As only an introduction to the topic, there will likely be future work to provide more complete guidance on applying system safety to autonomous systems in mining.

Andrew Scott, GMG Vice-Chair Working Groups and National Cluster Development Manager at METS Ignited, says: “GMG, as an industry-led organisation, is proud to have had the opportunity to facilitate this work with the global mining community. I look forward to the discussion this white paper will spark as well as further collaboration on the topic.

“I would like to thank all who provided their input and support.”

Autonomous drilling transition sets IAMGOLD’s Essakane up for longer mine life

The roots of IAMGOLD’s automation ambitions at the Côté gold project in Ontario, Canada, can be traced back to remote and auto drilling developments at its 90%-owned Essakane mine in Burkina Faso, which, according to a recent presentation from Zhi Jun Zhu, has resulted in significant operational benefits.

IAMGOLD launched the first automated drill rig in West Africa with assistance from Epiroc back in February at Essakane. This followed a series of automation steps carried out on the company’s fleet of Epiroc PV235 blasthole drills, beginning with the ‘Operator Assist’ phase back in 2016.

Added to the seven PV235 blasthole drills on site are five Sandvik D45KSs. These drills are working in medium-to-hard material of 100-250 Mpa rock where they drill 229 mm and 152 mm diameter holes on 10 m benches. They come with a single pass limit of up to 12.2 m in down-the-hole drilling mode.

The business case for adopting automation at the site, which began operating in 2010 and was expanded in 2013 to reach a mining capacity of 55 Mt/y, was centred around a capex versus opex dynamic – should the company purchase a new rig to increase drilling performance by 15%, or try to increase the use of automation on its existing seven PV235s to hit this goal?

Alongside this, the company wanted to provide its best drillers with the ability to operate multiple rigs simultaneously, enhance operational safety, support continued sustainability, and improve performance and productivity.

Zhu, who worked at Essakane as Technical Services Coordinator for five years prior to his current role as Autonomous Systems Engineer at Côté, explained during the recent GMG-led Autonomous Drills Virtual Forum: “During the start-up of the mine, the required fragmentation size was difficult to achieve because the ore was coming from the soft area where it was highly weathered and fractured. As the mine depth increased, the material got harder. As a result, the blasting fragmentation became harder to achieve. At the same time as the percentage of hard material increased, productivity of the crusher became a concern and bottleneck.”

With the last life of mine study in 2018 showing a required increase in the total material mined to keep up an average gold production rate of 400,000 oz/y – and the requirement to strip hard material from phase four, five, six and seven to reach a new ore zone from 2026 – the company needed to embed a suitable level of blasthole drill automation in advance of another expansion in the mine life.

Prior to 2016, Essakane required two people to operate a PV235 – one to guide the machine to the desired location and another to operate it.

This was neither safe or efficient, Zhu said, adding that hole deviation and sub-optimal fragmentation were also common with this setup.

Breaking down the project key performance indicators after the initial ramp up of remote and autonomous operation, Zhu said the company was looking for:

  • An improved drilling penetration rate of 15%:
    • 23 m/operating hour (propel + setup + drill); and
    • 28 m/drilling hour.
  • Improved drilling productivity from 63% to 75%:
    • Eliminate stoppage delays associated with lunch and shift change;
    • Lean drilling, less propel/tram and setup/positioning time.
  • Increased drilling capacity from 81,714 to 108,800 drilling meters/rig/year.

Having progressed from the ‘Rig Operator Assist’ mode in 2016, which used Epiroc’s Rig Control System, Surface Manager, Auto Level, first generation AutoDrill module, and Hole Navigation; the company has progressed to the ‘Rig Remote Operation’ phase where (Multi) Remote and AutoDrill generation two functions are employed.

This second-generation system represents a “big advance”, Zhu said.

“The system is very smart and could continuously optimise the engagement to deliver the desired result,” he said. “The only manual input required is the ‘aggressiveness’ setting, which balances the bit life with the penetration rate.”

This led to the launch of its first fully automated drill rig on February 8.

While the project is on course to hit all the above-mentioned KPIs, there have been other benefits including an operating hours improvement of 645 hours/year/rig; a 14,835 m/year/rig drilling metres gain; a $356,040/rig incremental annual production benefit; and a net cost saving of $202,794/rig compared with the equivalent rental equipment drilling cost.

All of these add to fewer people being in dangerous areas on the mine site – with all operators in remote operating centres – more consistent operation from a fuels/lubricants and drilling consumables perspective and, of course, less maintenance.

Reflecting on the implementation, Zhu noted several key required inputs for a successful automation implementation program.

“It is a critical requirement to have a reliable network connection between the on-board device and the remote operations office,” he said.

On top of this, the sensors on the machines need to be kept in top shape, meaning maintenance teams should evaluate their health on a regular basis and always keep spare parts available.

And, while fewer people will be needed to oversee drilling in autonomous mode, the skills level of the required personnel will be that much greater.

Some of the next steps at Essakane include improving the bandwidth and latency time for real-time control of multi-automated drills, developing a preventive maintenance system checklist, and carrying out a business case study on upgrading four PV235s to either Teleremote/AutoDrill 2 operation.

Zhu will no doubt bring these learnings and opportunities to the Côté gold development in Canada, which is expected to operate six blasthole drills in fully autonomous mode when ramped up, alongside more than 20 fully automated haul trucks. These will help the mine reach an average production rate of 367,000 oz/y of gold.

GMG examines functional safety in mine automation with latest guideline

The Global Mining Guidelines Group’s (GMG) latest guideline on autonomous systems will “provide clarity on the expectations between the various parties involved in delivering automation to mines”, Gareth Topham, one of the guideline project co-leaders, says.

“Whether it be fully autonomous or semi-autonomous, there are degraded modes or unexpected situations that people deal with every day in mines,” Topham, Principal Functional Safety at Rio Tinto, says. “To manage the removal of a potential control and introduce a technical solution as an alternative, we have to apply functional safety principles to confirm we are reducing the risks as much as we reasonably can.”

The GMG’s ‘Guideline for Applying Functional Safety to Autonomous Systems in Mining’ provides a common approach to applying functional safety to autonomous systems and references international standards within the context of the mining industry and its current maturity, according to GMG. It also describes clear expectations for the communication requirements to support change management and effective application.

“Functional safety is an important industry challenge as adoption of autonomous systems grows,” the GMG said. “While autonomous mining is an opportunity to remove people from potentially hazardous situations, there are also residual risks. Automatic protection systems in a mining environment need to respond to various kinds of errors and changes in conditions, such as human error, software failures and operational/environmental stress.”

To help readers navigate these risks, this guideline begins by identifying important reference materials and listing standards relevant to applying functional safety to various aspects of autonomous systems, the GMG says.

The core content of the guideline is an example of a functional safety lifecycle for applying autonomous systems in mining and identifies some key expectations and responsibilities for providing information, documentation and support at each stage. It also offers high-level guidance on software development, verification, and validation; competency management; cybersecurity; and assurance documentation, according to GMG.

Industry alignment on the expectations and requirements related to functional safety is also a key goal for this guideline.

Andrew Scott, Principal Innovator at Symbiotic Innovations and GMG Vice-Chair Working Groups, says: “Experts from a wide range of stakeholder groups – suppliers, consultants, operators, regulators and system integrators – have been engaged in this guideline’s development and extensive peer review. The engagement in this project has been an excellent example of how traditional competitors can come together to create a safer future through the GMG community.”

Because functional safety for autonomous systems in mining is a rapidly evolving topic, this guideline is expected to evolve and add any appropriate detail over time to align with new and updated standards and consider emerging concepts and technological advances.

A separate GMG project on system safety is also ongoing and will complement this guideline by addressing adjacent topics such as safety case and risk management, human factors, integration, and verification and validation, GMG says.

Battery-electric vehicles dominate in GMG Electric Mine project survey

A survey aimed at defining priorities for the GMG Electric Mine Operational Knowledge Sharing Platform project has highlighted that despite the rise of other diesel-alternative technologies, battery-electric vehicles (BEVs) continue to be the area of focus for the mine electrification community.

Respondents to the survey were asked about what types of equipment to prioritise, with haul trucks and LHD trucks coming up top out of all equipment and BEVs topping the results when it came to electric equipment types.

In terms of the latter, BEVs beat off competition from hydrogen fuel cells, trolley assist systems and tethered equipment, commanding more than three quarters of the votes.

GMG remarked: “Some commentators noted that this will be different depending on underground or open pit (eg BEVs underground, trolley for open pit), so this result may be skewed due to the large representation of underground mining in the survey.”

In the survey, performance was noted as the highest priority in terms of types of information that will provide value, GMG said.

However, the results of the workshops held under the project identified that there would be certain types of information that can be used to provide value in overlapping areas (eg they may help operations make performance comparisons and also identify operational or maintenance needs).

Highlights include:

  • Information about the daily cycle and time usage in comparison to diesel;
  • Identifying what information should be available in real time;
  • Information or metrics for comparing charging strategies;
  • Information for assessing and updating charging infrastructure;
  • Training information for operators, safety personnel and maintenance technicians; and
  • Information on heat generation.

And the following priorities were identified in the survey and workshops when it came to the uses of this information:

  • Understanding capital and operating costs;
  • Developing the business case;
  • Developing a charging philosophy and strategy;
  • Understanding safety requirements and improving safety; and
  • Understanding infrastructure, design and planning requirements.

The GMG noted: “These results may be influenced by the higher representation of underground mining professionals and that 64% of respondents are North American and similar representation at the workshops.”

The survey was open between April and June 2020 with 95 respondents (as of June 9). Underground mining was more heavily represented than surface, but many respondents specialised in both, according to GMG. Professionals (engineers, geologists, metallurgists, etc) were the most highly represented (26%) while corporate senior management (17%) and corporate technology leaders (17%) were also well represented.

The GMG Electric Mine Operational Knowledge Sharing Platform project aims to create a neutral platform to capture performance data for electric surface and underground equipment based on the industry’s knowledge and experience, GMG says.

Michelle Ash to become CEO of Dassault’s GEOVIA division

Dassault Systèmes says it has appointed Global Mining Guidelines Group (GMG) Chair, Michelle Ash, as CEO of its GEOVIA software division.

Ash will help shape strategy to build growth across the company’s Natural Resources sector, as well as deliver next-generation solutions based on the 3DEXPERIENCE platform, which integrates all the technologies and capabilities that leverage knowledge and know-how into one “cohesive digital innovation environment”, according to Dassault.

Ash, who has been chair of GMG since May 2018, was previously Chief Innovation Officer at Barrick Gold. She has more than 20 years’ experience in the mining and manufacturing sectors with a focus on business improvement and change management.

It is not clear if she will continue her role with GMG following this appointment.

GEOVIA, meanwhile, became part of Dassault back in 2012 when the France-based company acquired geological modelling and simulation company Gemcom Software International. Dassault renamed the division GEOVIA shortly after the deal was completed.

GMG launches cybersecurity and electric mine working groups

The Global Mining Guidelines Group (GMG) says it has just launched two new working groups on cybersecurity and the electric mine to create safe and sustainable mines of the future.

The Cybersecurity Working Group aims to help mining stakeholders as they look to design safe, secure, reliable and resilient cybersecurity infrastructure that adheres to regulatory, trust, and privacy best practices, GMG said.

The group is to provide guidance for the industry to access and implement existing solutions, be responsive to the priorities of the industry, and look for projects that will benefit from GMG’s open, collaborative principles and processes, it added.

“As digitalisation increases in our industry, so does the risk of cybersecurity incidents,” says Andrew Scott, GMG Vice-Chair Working Groups and Principal Innovator at Symbiotic Innovations. “Industry-wide knowledge sharing and collaboration are important for mitigating these risks.”

Scott added: “The topic has come up in many existing GMG projects including those on autonomous systems, artificial intelligence and interoperability, and it is clear that cybersecurity is a high-priority concern among mining stakeholders.”

The group will work closely with the Mining and Metals Information Sharing Analysis Centre (MM-ISAC) to collaborate on and identify existing projects and prevent duplication, according to GMG.

The Electric Mine Working Group, meanwhile, aims to accelerate the advancement and adoption of electric mining technologies in underground and surface contexts. It will cover all-electric technologies that are replacing those that typically use diesel.

Key objectives include developing guidelines and sharing information on using and testing electric technologies and designing electric mines.

GMG Managing Director, Heather Ednie, said: “The shift toward the electric mine in surface and underground contexts is indicative of our industry’s growing commitment to reducing greenhouse gases and providing safer working environments.

“Previous GMG work on battery-electric vehicles in underground mining brought together a community of companies leading the way in developing and adopting electric mining technologies. As these technologies are increasingly used in surface mines, the need to expand the community has become clear.”

This group will work in parallel with the International Commission on Mining and Metals (ICMM) and its Innovation for Cleaner Safer Vehicles (ICSV) initiative to ensure that the initiatives support each other, GMG explained.

Once launched, these groups will form a steering committee to refine the scope and objectives and identify early projects, GMG said.

The Cybersecurity Working Group will have its introductory virtual meeting on November 11. The kick-off workshop is to define what the industry needs from a cybersecurity perspective; it will be held at the Kennedy Space Centre in Florida, USA. on December 5, held in partnership with the MM-ISAC.

The Electric Mine Working Group will have its introductory virtual meeting on November 21.

GMG helping miners leverage machine learning

The Global Mining Guidelines Group (GMG) has published a new whitepaper that, it hopes, will better equip mining companies to leverage artificial intelligence (AI) and machine-learning technologies.

The Foundations of AI: A Framework for AI in Mining offers an overview of the process of planning for and implementing AI solutions for mining companies, GMG said.

GMG explained: “AI-based innovation is being used increasingly in the mining industry as a means to improve processes and decision-making, derive value from data and increase safety, but the levels of operational maturity are variable across the industry.

“Though many mining stakeholders are adopting AI, there is still uncertainty about the technology and how it can be harnessed in the mining industry.”

This white paper – developed collaboratively through workshops, conference calls and online collaboration tools – addresses a variety of concerns, such as the challenge of establishing data infrastructure, apprehensions about the effect on the workforce and worries about failure after investing substantial time and funds into an AI project, GMG said. “It offers a realistic strategy for building a foundation for planning, implementing and moving forward with AI.”

The primary audience is those in charge of introducing or expanding the use of AI in mining companies, according to GMG.

Rob Johnston, Project Manager at CITIC Pacific Mining and GMG AI Project Leader, says: “There has been a recent explosion in the application of AI in industry, and this document aims to assist mining companies to fully embrace this exciting technology and drive business value.”

Having this information available will also help cut through the hype that surrounds AI, according to GMG.

Andrew Scott, GMG Vice-Chair Working Groups and Principal Innovator at Symbiotic Innovations, said: “Although mining stakeholders generally recognise the value of understanding the technology, many are intimidated by the concept and see expertise in AI as a very specialised knowledge set, so this will help them start off on the right foot.”

This document will also be useful for those who are part of the ecosystem that surrounds mining companies, which comprises those assisting in applying the technology, culture and safety considerations and regulatory frameworks that are necessary for a successful AI strategy, according to GMG.

Speaking from his perspective as a solution provider, Kevin Urbanski, CTO at Rithmik Solutions, says the white paper will provide “current and future customers with a macro view of artificial intelligence and related solutions”, while helping mining operations to “identify opportunities to apply these powerful algorithms within their organisations.”

He added: “Mining companies know best what their needs are, and this document will help them match those needs with what’s possible.”

Urbanski thinks the document will also help to standardise communications around the technology, saying it will “provide great level-setting, ensuring that we and our customers are speaking the same language when talking about AI”.

Johnston, meanwhile, says that while this publication is an important step, the document will be reviewed and updated as needed: “The field of AI moves so fast that this will be a document that will be updated regularly in order to remain relevant to the industry.”
