Mining-focused consortium delves into mine closure ‘transition’

The University of Queensland’s Sustainable Minerals Institute (SMI) has published the first six project reports of the Social Aspects of Mine Closure Research Consortium.

Researchers at SMI’s Centre for Social Responsibility in Mining (CSRM) led the mine closure-related projects, which, they say, examined Indigenous employment opportunities, public participation and government engagement processes, integrating social aspects into industry partners’ closure planning, governance and regulation and mining as a temporary land use.

“The consortium is a multi-party, industry-university research collaboration established to conduct research that challenges accepted industry norms and practices and demands new approaches that place people at the centre of mine closure,” SMI said.

CSRM Director Professor, Deanna Kemp, said publishing the reports contributed significantly to the mine closure literature and provided stakeholders with the latest information.

“In the consortium’s first year of operation, we focused on establishing data and knowledge to inform subsequent research. This strategy is evident in the diversity of projects undertaken,” she said.

“A core theme has been around ‘transition’; that is, viewing closure not merely as an end-point of mining, but as a transition to a post-mining future in which social change continues long after a mine ceases to be productive.”

She said the consortium was now developing its 2020 research plan, “which will build on this solid foundation and deliver on our consortium partners’ priorities”.

Major mining companies such as Anglo American, BHP, MMG, Newcrest, Newmont, OceanaGold and Rio Tinto are consortium members, with the work sitting under the SMI’s Transforming the Mine Life Cycle strategic research program as one of three research themes (transitioning through closure).

Under the ‘Indigenous groups, land rehabilitation and mine closure: exploring the Australian terrain’ project, two challenging areas at the interface of mining and Indigenous communities in Australia are being addressed.

This includes, one, the persistent lack of direct employment of Indigenous landowners on mines operating on their land; and, two, increasing expectations that mining companies engage local communities in closure planning and closure criteria setting as a prerequisite for relinquishment.

“The approach taken seeks to build on one of the greatest assets Indigenous people possess; their attachment to and knowledge of their land,” the SMI said.

In the ‘Integrated mine closure planning: A rapid scan of innovations in corporate practice’ project, the study aims to identify novel approaches used by consortium member companies to integrate social dimensions into closure planning.

Identifying these approaches promotes knowledge exchange between the companies and provides direction for future research and innovation for mine closure performance, according to the SMI.

“We found that the companies are at various stages of integrating environmental, social and economic factors into planning (at all stages of the mine lifecycle),” it said.

The ‘Participatory processes, mine closure and social transitions’ project examines the fact that, in closure planning, the focus of public participation is on identifying and managing the changes brought about by closure.

The project will ask: “What participatory processes contribute to a smooth transition to a post-mining future? How can public participation contribute to a positive socio-economic legacy of mining?”

Undertaken as part of the Social Aspects of Mine Closure Research Consortium, this project will address these questions.

The SMI said: “Researchers found few studies documenting the specific application of participatory processes to mine closure. Even fewer provide analysis to glean broader insights beyond time- and context-specific details.”

This project was designed as an exploratory, desktop study to ascertain what is known and documented about participation in mine closure. It is intended to provide an overview of key principles and to function as a repository of case studies to support future research, according to the consortium members.

The ‘Government engagement: insights from three Australian states’ project sought to establish current state priorities for socially responsible mine closure and smooth regional post-mining transitions in the Australia state jurisdictions of New South Wales, Queensland and Western Australia.

It concentrated on priorities that are not yet evident in legislation and cultivating state authorities’ interest in the work of the consortium, according to the SMI.

“The project aimed to: better understand current and emerging expectations and role of Australian governments in ensuring attention to social aspects of closure; identify government strategies for improving the ‘afterlife’ for mining communities and regions; articulate regulator roles in protecting the public good and ensuring a positive socio-economic legacy of mining; facilitate two-way communication between the consortium and governments and identifying ways for government departments to connect to the consortium’s work.”

The project, ‘Mining as a temporary land use: industry-led transitions and repurposing’, showed that post-mining land use and associated economies have become a priority issue in mine lifecycle planning.
This scoping project starts from the position that reconceptualising mine ‘closure’ may enhance the industry’s contribution to sustainable development, the SMI said. It reframes mining as a “temporary land use”.

“The primary focus of this research is on identifying examples of post-mining repurposing of land and related economic transitions that are being led by industry,” the SMI said. “Transitions led by state or other actors (eg civil society groups) provide additional inspiration for industry-led opportunities. Our findings provide an initial repository of cases that different parties can refer to in making decisions about post-mining futures.”

Lastly, the ‘Social aspects of mine closure: governance & regulation’ project extends previous CSRM work on closure regulation and closure bonds.

The project partners reviewed mining regulations across 10 jurisdictions around the world, with the objective being to build a knowledge base of how regulators are approaching social aspects of closure. This involved collating, organising, and characterising over 40 acts, regulations, and policy documents.

“We found that no jurisdiction had passed regulation specific to social aspects of closure and all tended to focus on biophysical aspects of closure,” the SMI said. “Social aspects of mining received attention in relation to approvals, but not generally for closure.”

The evidence gathered in this project can be mobilised to support subsequent work, according to the partners, who suggested a collaboration between industry, government, and other stakeholders to develop model regulations that account for a variety of perspectives and reflect realistic operational parameters.

Sandvik showcases digital mining developments in Brisbane

Last week, close to 300 leaders from the mining, construction and quarrying industries from Australia, Japan and Indonesia met in Brisbane, Australia, for a two-day summit, hosted by Sandvik, to showcase best practice examples of digitalisation.

The Digitalization in Mining event, on December 3-4, allowed Sandvik to demonstrate its latest digital offering and introduce participants to the latest innovations across its product portfolio, including process optimisation with OptiMine®, information management through My Sandvik digital services and autonomous operation with AutoMine ̶ together with the latest equipment in underground and surface drilling, loading and hauling, crushing and screening and the rock tools management system.

During the event Sandvik also announced two product launches: AutoMine Access API, which gives mines the power to connect non-Sandvik equipment to AutoMine, and its first Stage V compliant underground loaders for hard-rock mining applications.

Jim Tolley, Vice President, Sales Area Australia Pacific, Sandvik Mining and Rock Technology, said digitalisation is helping companies to grow and optimise their operations. “Our partners were keen to join us at this event because they know that digitalisation has a critical part to play in making their mines sustainable for the future.”

Day one of the event featured speakers from mining companies across Australia, as well as leaders in mining technology, process optimisation and automation. They explained the benefits their organisations have gained by implementing automation and process optimisation solutions, as well as the accompanying change in mindset, according to Sandvik.

The following presentations set the program for the day, followed by a panel discussion:

  • Shaping the Industry Digital Ecosystem (Sandvik);
  • Holistic Perspective, Focusing on Productivity, Safety and Optimised Machine Performance (Byrnecut);
  • Developing the Mine of Tomorrow (Barminco Ltd);
  • Machine Learning  ̶  Keeping it Real with Case Studies from across the Mine Value Chain (PETRA Data Science);
  • Capturing Opportunities for Digital and other Product Technology Solutions (Rio Tinto);
  • Automation Technology to Improve Efficiency and Consistency in Longwall Development Operations (Glencore);
  • Direction of Technology and Automation (Newcrest); and
  • Data Privacy, Rights and Control (Sandvik).

Pat Boniwell, Managing Director, Byrnecut Australia, said the industry will improve productivity, safety and optimise machine performance through a more “fundamental understanding” of the individual processes that make up our operations.

“New technology, automation, data transfer and analysis will all assist us in increasing the utilisation of our resources,” he said. “Data is essential, but if it is not being looked at then we are just gathering data for the sake of it. We need to continue to increase the levels of engagement between all stakeholders.”

He concluded: “We are doomed to failure unless we take our people with us and are prepared to question and be challenged.”

PETRA CEO, Penny Stewart, meanwhile, homed in on machine learning, which, she said, powers “digital twin prediction, simulation and optimisation to increase mine productivity, efficiency and yield, by showing engineers and supervisors how to reproduce their ‘best performance’ 24 hours a day, seven days a week”.

She added: “PETRA’s MAXTA™ Suite digital twin applications provide platform agnostic software-as-service operational decision support across the mine value chain ̶ from resource engineering through to processing plant set point optimisation.”

Day two of the event began with a presentation on sustainability by Henrik Ager (pictured), President, Sandvik Mining and Rock Technology, explaining how critical it is for long-term performance.

“Driving productivity and greenhouse gas efficiency together is going to be key for us at Sandvik, improving productivity and greenhouse gas efficiency will be the best way for us to add value for our customers,” he said. “My view is that the more we link our sustainability targets to normal business targets and find ways to combine them to achieve a common good, the better chance we have to deliver on them.”

Also, during the second day, delegates had the opportunity of a virtual visit to several Sandvik customers, including: Northparkes Mine (Australia), Resolute Mining Syama mine (West Africa), RedBull Powder Company (New Zealand) and Aeris Resources Tritton mine (Australia).

Harry Hardy, General Manager Customer Accounts, Applications Engineering and Marketing, Sandvik Mining and Rock Technology, Sales Area APAC, said the company often gets asked for reference cases and data to illustrate the value and payback of digital solutions. “Over the two days of the conference, our customers were able to share their own experiences and quantitatively demonstrate how our solutions have helped increase their productivity, reduce their production costs and increase their safety.”

Newcrest rolling out GE Mining collision avoidance system at Lihir

Newcrest Mining’s Lihir gold operation in Papua New Guinea is, this month, due to go live with a full installation of GE Mining’s collision avoidance system (CAS).

This follows the CAS being fitted to equipment in the Telfer open-pit mine (Western Australia) and the gradual installation of units at Lihir. Since installation 12 months ago at Telfer, vehicle-to-vehicle collisions have reduced by 33%, Newcrest said in its recently-published sustainability report.

Proximity detection technology has been progressively rolled out across the company following incidents at its operations involving collisions or near misses between vehicles and other vehicles, vehicles and pedestrians, and vehicles and infrastructure.

Supported by Newcrest’s Executive Committee, a working group comprising representatives from Newcrest’s Group Safety, Technology & Innovation, Group Supply, and key stakeholders from each of its sites, developed a strategy to deploy the technology and identified solutions suitable for use in surface and underground mining, supplied by GE Mining and Newtrax Mineprox, respectively.

Newcrest started implementing GE Mining’s CAS at Lihir back in October last year. Around 1,500 employees were to be protected in addition to up to 250 vehicles.

In addition to the GE Mining contract, Telfer and Gosowong (Indonesia) underground operations have awarded tenders to Newtrax to deploy Mineprox on the mobile mining fleets. Contractor mobilisation at Telfer commenced in September 2018.

And there could be more contract awards on the way.

Newcrest said: “Given the anticipated automation and teleremote system programme of works at Cadia (New South Wales), the business has adjusted the criteria for its proximity detection solution and is expected to award a contract soon.”
