Thiess’ Mount Pleasant Operations (MPO) team has been recognised by the New South Wales Resources Regulator for its industry-leading rehabilitation practices, it says.

Recently publishing an information release about the operation’s rehabilitation controls, the regulator recognised how the team enables long-term landform design stability and manages surface water drainage networks through strong quality assurance measures, according to Thiess.

Thiess, in collaboration with MACH Energy Australia (MACH Energy), has introduced quality assurance controls including the sign-off of inspection and test plans across each construction phase – design, bulk shaping, topsoil placement, ripping and seeding and drain construction, to support progressive rehabilitation and reduce ongoing liabilities.

Thiess Environment & Civil Manager, James Anderson, said these controls provide an unmatched foundation for sustainability, maximising rehabilitation outcomes and managing compliance with confidence.

“The implementation of these controls is an example of how we channel our global experience and insight to create advantages for our projects,” Anderson said. “Our proven systems and processes help deliver immediate efficiencies, reduce rework time and lower life of mine costs for our clients.”

Some 2.5 km from Muswellbrook in the Upper Hunter Valley of New South Wales, the Mount Pleasant Operation’s complex landform design aims to meet end land use objectives while minimising impacts and delivering a more visually appealing landscape for the local community, Thiess explains.

Since 2017, Thiess has provided construction services to MACH Energy including bulk profiling and shaping of mine spoil, construction of drainage networks, erosion and sediment control structures, final surface preparation, installation of habitat features, topsoil ripping, seeding and planting.

This includes delivering the operation’s first rehabilitation two months before first coal was mined.

Thiess Environment Superintendent, Peter York, says the team’s robust processes and strict quality controls are critical to ensuring rehabilitation is delivered on time and to design specifications.

“Our rehabilitation is not just about quantity,” York said. “The final outcomes have to be quality as well, capable of meeting an agreed end land use. To help facilitate this, we work with MACH Energy to identify improvement opportunities to proactively manage environmental risks and adapt to changing regulatory conditions and evolving community expectations.

“Our systematic approach is helping us achieve industry firsts for rehabilitation while restoring self-sustaining native woodland ecosystems.”

Thiess will continue to deliver a full suite of mining services at the Mount Pleasant Operation, including rehabilitation, under a new 4.5-year contract extension commencing in April 2022.

The organisers of the Charge On Innovation Challenge have reported an overwhelming response to the preliminary phase, which closed on July 31, with 21 mining companies joining as patrons, over 350 companies from across 19 industries registering their interest as vendors, and more than 80 organisations submitting expressions of interest (EOI).

The challenge, a global competition, is expected to drive technology innovators across all industries to develop new concepts and solutions for large-scale haul truck electrification systems aimed at significantly cutting emissions from surface mining. It also aims to demonstrate an emerging market for charging solutions in mining, accelerate commercialisation of solutions and integrate innovations from other industries into the mining sector.

BHP, Rio Tinto, and Vale, facilitated by Austmine, launched the Charge On Innovation Challenge in May of this year, initiating the EOI process on May 18. Since the initial launch, Roy Hill, Teck, Boliden, Thiess, Antofagasta Minerals, Codelco, Freeport McMoRan, Gold Fields and Yancoal came forward as patrons by early July.

The latest release has highlighted another nine miners to join as patrons. This includes Barrick Gold, CITIC Pacific Mining, Evolution Mining, Harmony Gold, Mineral Resources Ltd, Newcrest Mining, OZ Minerals, South32 and Syncrude.

The patrons, supported by Austmine, will assess the proposals over the next month and select a shortlist of vendors who will then formally pitch their challenge solutions.

At least one of these proposals has come from ABB, which confirmed earlier this month that it had submitted its ideas for the challenge using its mine electrification, traction and battery system eand charging infrastructure expertise.

At the end of the pitch phase, the challenge patrons will look to select the most desirable charging concepts identified as having broad industry appeal and application, as well as providing a standard geometry that enables chargers to service trucks from different manufacturers. The first concepts could be ready for site trials in the next few years, according to the organisers.

BHP’s Charge On Innovation Challenge Project Lead, Scott Davis, said: “The Charge On Innovation Challenge is a great example of the current collaborative work being done by the mining industry in seeking solutions to decarbonise mining fleets. The challenge received interest from companies based in over 20 countries, showing the truly global reach of the opportunity to help reduce haul truck emissions.”

John Mulcahy, Rio Tinto’s lead for the Charge On Innovation Challenge, said: “Twenty-one mining companies, all focused on lowering carbon emissions, have joined as patrons. Together we’re encouraging technology innovators to help us introduce large-scale haul truck electrification solutions. The sooner we bring these technologies to market, the sooner we can introduce them to our fleet, and reduce emissions.”

Vale’s Charge On Innovation Challenge Project lead, Mauricio Duarte, said: “We are very happy with the results of the first phase of the project. It´s still early to talk about the success of the challenge, but it is clear that the industry has reached a new level: we worked together on a common sustainability agenda and we will work collectively to reach our goals, gaining safety and speed on our way to low carbon mining.”

Thiess is expanding its 240-t fleet in Chile with five new electric drive Liebherr T 264 mining trucks, cementing its commitment to growth in the region.

Thiess’ Executive General Manager Americas, Darrell White, said the fleet addition would further bolster Thiess’ capability and deliver productivity and efficiency gains for clients.

“South America is essential to Thiess’ long-term growth and building our diversification into commodities such as copper and gold,” White said. “The T 264s boost our fleet numbers and provide our clients with the opportunity to increase production capacity.

“This commitment to new fleet follows our recent investment in infrastructure, which includes a dedicated maintenance workshop, and building workforce capability through in-house and industry scholarship and pathway programs.”

Liebherr Chile’s Mining Division Director, Dale Clayton, said the Liebherr partnership with Thiess spanned three decades and enabled new products to enter the market, including the recently upgraded T 264s to Chile.

“The T 264 truck has a 240-t nominal payload capacity and an impressive payload-to-empty-vehicle weight ratio, leading to faster acceleration speeds, better speed on grade and higher hauling capacity, resulting in shorter cycle times and a lower cost per tonne,” he said said. “The combination of a high-power Cummins QSK60 2,700 hp (2,013 kW) diesel engine with the extremely efficient Liebherr AC electric propulsion system allows for maximum productivity and reduced downtime.”

He added: “Our La Negra Facility and Reman Centre is well placed to provide spare parts and components as well as training and technical support, and our teams are experienced in servicing mining fleet in the unique conditions Chile offers.”

The T 264s will be manufactured at Liebherr Mining Equipment Newport News Co in Virginia, USA, and will then be shipped to Chile. Assembly of the trucks will take place at Liebherr’s La Negra Facility before being transported to site, ready for commissioning.

AECI Australia has been awarded a five-year contract extension by contract miner Thiess for the supply of bulk emulsion explosives, initiating systems and related services for mines in Queensland and New South Wales.

This contract consolidates AECI’s base business in Australia and further strengthens the relationship between the two companies, which began in 2014 when AECI entered Australia to support this major mining customer, AECI said. The two also have long-standing partnerships in Indonesia and in several countries in Africa.

The Australian contract, using AECI’s existing in-country capabilities and infrastructure, includes supply of bulk emulsion explosives formulations produced at AECI’s site in Bajool, Queensland, as well as gassing technology for down-the-hole delivery by Thiess; supply of ammonium nitrate; and supply of the Intellishot® electronic initiating system and booster.

Mark Dytor, AECI Chief Executive, said: “AECI Australia is celebrating the achievement of seven years worked without a lost-time injury. We are proud to deliver a safer, innovative and cost-effective product offering that enables ‘One AECI, for a better world’. Better Mining is one of our sustainability goals because we recognise the importance of making global mining safer and more circular.

Antofagasta, as part of its sustainability efforts, has joined the Charge On Innovation Challenge as a patron.

The initiative, which counts BHP, Rio Tinto and Vale as founding patrons, seeks to develop solutions to charge the batteries of electric mining trucks safely, quickly and sustainably. This is essential in order to replace the use of diesel in these trucks and the emissions it produces, the challenge organisers say.

The goal is to enable trucks of 220 t or more to stop using diesel and run on electric batteries, just like other electric vehicles. In order to achieve this, it is essential to develop a battery charging system that does not use polluting fuels and, at the same time, allows the extraction trucks to operate as they usually do.

Today there are already efforts underway to develop and use electric trucks, but those are for trucks of a smaller tonnage (100 t) which can regenerate their own energy, Charge on Innovation says. The collaborative work with the Charge On Innovation Challenge seeks to develop solutions for larger trucks.

Iván Arriagada, CEO of Antofagasta, said: “As a mining group focused on innovation, we are interested in collaborating and contributing to the development of the industry for the future. That is why we decided to participate in this challenge, which is key to being able to use electric trucks and significantly reduce greenhouse gas emissions.”

As part of its Climate Change Strategy, from 2022, the electricity supplying Antofagasta companies will come from renewable sources. Antofagasta’s Zaldívar mine has been operating from clean energy sources since July 2020.

Thanks to these advances and other measures adopted by the company, Antofagasta was able to reduce its greenhouse gas emissions by more than 580,000 t since 2018. Its new goal is to decrease those emissions by an additional 30% between now and 2025.

The Charge On Innovation Challenge was launched by BHP, Vale and Rio Tinto in partnership with Austmine. It has since added Roy Hill, Teck, Boliden and Thiess as additional patrons.

Thiess has signed an agreement with Australia-based Mine Energy Solutions that could see the use of locally-sourced gas to displace diesel in large mining trucks using MES’ “currently available and proven” dual-fuel technology.

The agreement to bring lower emission, dual-fuel technology to Thiess’ mining fleet represents a first for a mining services provider in the industry, the company said.

The partnership will commence with the conversion of a fleet of six mining trucks and seek to source gas on site to allow the removal of the equivalent B Double diesel deliveries from local highways, reducing congestion and making it safer for regional families, Thiess said. Longer term, Thiess and MES will seek to expand to full fleet conversion before exploring further opportunities both within Australia and Internationally.

Thiess CEO, Douglas Thompson, said: “Partnerships like this ensure Thiess is playing a role in reducing emissions on our operations and leading the path to decarbonisation of the industry.”

MES’ CEO, Adrian Abbott, added: “We’re proud to partner with Thiess and apply this technology in the Bowen Basin. Our focus is to use locally-sourced gas through the capture and use of fugitive methane contained in the coal resource to enable the average mine site to reduce their greenhouse gas footprint by more than 550,000 t of CO2-e per annum.”

MES’ High Density Compressed Natural Gas (HDCNG®) technology was previously trialled at the New Acland coal mine in Queensland, Australia, with help from New Hope Group and Hastings Deering. This saw a Cat 789C haul truck converted from diesel use to dual-fuel operation using natural gas as the dominant fuel through sequential gas injection.

Thiess, in partnership with its client Glencore, has come up with a proactive approach to environmental management to ensure dust, noise and blasting emission impacts are minimised on local communities at the Mt Owen coal mine in New South Wales, Australia.

Working together with Glencore, the team has developed a range of controls including leadership training and education sessions, noise and dust risk forecasting, targeted sound power testing of operating equipment and real-time monitoring technology.

Thiess Senior Environment Advisor, Linda Lunnon, said the real-time data enables the operational team to monitor dust and noise levels and respond swiftly to changing weather conditions.

“Paired with regular visual inspections, the technology provides further guidance throughout each shift, enabling our leaders to readily modify operations as needed,” she said. “The system also triggers SMS alerts to relevant personnel if dust or noise levels reach a defined threshold. This provides a prompt for operational staff to reassess controls and implement further actions if required.”

Lunnon said the forecasting systems also allow the Mt Owen team to plan for adverse weather conditions.

“Dust and noise are two of the highest environment risks for our projects in the Hunter Valley, and we are continually monitoring and refining controls that can assist in managing these risks,” she said.

Thiess’ environment team believes engaging its people is critical to effectively managing risks.

“We prioritise continued support and coaching of our people to ensure they understand the context and importance of our environmental controls and can get optimal value from the systems we’ve developed,” Lunnon said. “We educate them on the monitoring of data, trends and how they can apply their knowledge to minimise short-term and longer-term community impacts.”

Thiess Environment and Civil Manager, James Anderson, recognises his team’s ability to stay abreast of emerging environmental trends in industry and legislation to reduce risks and identify and action opportunities for our client.

“Our Mt Owen team works closely with our wider operations in the Hunter Valley to collaborate on solving problems and achieve tailored dust and noise management solutions,” Anderson said.

More broadly, the Mt Owen team works with Thiess’ wider operational and technical teams to design and deliver integrated solutions that optimise overall mining and rehabilitation efforts.

“Each project leverages our global insight to provide local value, with our head office team offering industry-leading environmental insights across each of our operating countries,” Anderson said. “Our proven experience managing the full suite of environmental services on mine sites ensures we continually deliver exceptional outcomes for our clients.”

Thiess cuts probe drilling costs by leveraging advanced void management system

Automation, Explosives and blasting, IoT, Mining services, Mining software, , , , , ,

Thiess says its mine planning team is pioneering the development and use of an advanced void management system that is informing probing, drill pattern and blasting design.

The holistic system gives the contractor’s office and field-based teams immediate access to a central database of void information to support better, faster decision making and task optimisation.

Thiess General Manager WA/SA (Acting), Matt Henderson, said the system focuses on capturing, monitoring and understanding existing voids to help the project team manage and backfill where required.

“It gives us and our client a clear understanding of the geological and geotechnical risks associated with the project and how to best address them,” Henderson said. “This flows from mine design into operations, enabling our project team to manage and mitigate risk to our people and delivery.”

Thiess Mine Planning Manager, Ravi Achari, said the system, designed to enable verticle mining through extensive networks of underground voids (drives, development workings, workings, vertical rises and large slopes), was developed to improve safety and provide greater certainty in the company’s delivery.

“The system was developed using insights and learnings from a number of technologies currently available on the market, but without integration were unable to provide the required outcome,” Achari said. “We also leveraged insight from our void officers and surveyors, and drill and blast, geotechnical and mine planning engineers.”

Achari confirmed the new system enables his team to determine the right solution specific to each void.

“The system uses historical plans, probing and drilling data to survey the position and size of the old workings,” he said. “This includes checking the location and attributes of the voids we find against the recorded data to verify any changes in size or shape.

“Our findings will then inform our safety zone and backfilling requirements.”

Incorporating over five-years of proven void management processes and procedures, the system delivers client benefits by enabling Thiess’ team to mine additional tonnes.

“The system gives a precise delineation of the voids informing a more tailored drill and blast design that allows additional recovery of the commodity,” Achari said. “It has also enabled a reduction of probe drilling costs by up to 25%, representing a substantial cost saving.”

To date the system has helped manage and treat over 25 km of underground voids and stopes in Western Australia, and is currently being leveraged to develop an integrated drill and blast reporting system for Thiess globally.
