Orica announces commercial launch of wireless blast initiation solution, WebGen 200 Surface

Orica has announced the commercial release of WebGen™ 200 Surface, its latest wireless blast initiation solution tailored to surface mining applications.

Developed based on the success of more than 5,000 WebGen 100 blasts around the world, containing over 150,000 primers, WebGen 200 Surface will change how the industry blasts, resulting in more safer and efficient blasting for customers, according to the company.

The company conducted the first surface blast with WebGen 200 at TerraCom’s Blair Athol coal mine in Queensland, Australia, at the back end of 2022, as part of its Alpha trial program to verifiy and validate product testing in the field. Another trial at a partner customer mine in northern Chile has since followed.

Specifically designed for surface mining applications, WebGen 200 Surface eliminates physical wired connections to a blast or within the blasthole, opening up a whole new range of possibilities, Orica says. It enables customers to optimise their entire mining process from reducing exposure on bench to geological hazards, such as stemming dust, working next to highwalls, reducing vehicle interactions, and removing people from harm’s way.

The WebGen 200 system revolutionises mining operations by enabling customers to carry out operations during the lightning storm season or turning a loaded blast into a temporary haul road with the award-winning blasting method Mine Schedule Flexibility, the company said.

Orica Senior Manager, WebGen Commercialisation, Rhys Patterson, said: “It is the culmination of years of research and development across technology, marketing, commercial, supply and manufacturing teams. We are pleased to announce that WebGen 200 Surface is now commercially available for our customers.”

In addition, the safe passage of mining equipment over loaded blastholes by maintaining parallel mining, and drilling, and loading activities is now a reality, which can significantly increase the vertical advance of surface mines, Orica says. Production delays associated with exclusion zones around loaded blast patterns during lightning storms can also be eliminated using WebGen.

Orica’s global underground customers started the transition to WebGen 200 Underground Pro, with Newmont Borden being the first underground customer reaping the benefits of adopting this technology in late 2022. Engineered to deliver robust safety and reliability, the four variants of WebGen 200 (WebGen 200 Surface, WebGen 200 Surface Pro, WebGen 200 Underground Pro and WebGen 200 Dev) have been built with enhanced capabilities, security, and versatility, ensuring it meets the extreme mining conditions faced by surface and underground customers.

Orica, Epiroc and Agnico Eagle carry out world-first development charging milestone at Kittilä

Orica and Epiroc, in partnership with Agnico Eagle Mines Limited, have successfully commenced live blasting with Avatel™ – the world’s first semi-automated wireless underground development charging solution at Agnico Eagle’s Kittilä mine in Finland.

The milestone brings to life an industry-driven concept that dramatically improves safety at the face, which is one of the highest risk activities in underground mining today, Orica and Epiroc say.

Avatel enables a single operator to prepare and wirelessly complete a full charging cycle from the safety of an enclosed cabin while offering the best available blast outcomes through the integration of Orica and Epiroc’s flagship digital, automation and blasting technologies.

The first successful blast was loaded and fired on November 22, 2022, comprising 61 Orica WebGen™ 200 Dev wireless primers and 295 kilograms of Orica’s Subtek™ bulk emulsion loaded to a development face at the Kittilä mine.

Orica Chief Technology Officer, Angus Melbourne, said: “Together with Epiroc and Agnico Eagle we are extremely proud of the team in creating a solution that keeps people out of harm’s way during what is considered one of the highest risk activities for underground miners around the globe.

“With Avatel, we can now effectively manage risk for the people who spend the most time every shift directly exposed to hazards at the development face while delivering all of the blast optimisation benefits that Orica’s flagship technologies bring. The combination of digital, automation and wireless blasting technologies and by partnering with customers and peers, we can continue to solve the industry’s biggest challenges across safety, productivity and sustainability, together.”

Sami Niiranen, President for Epiroc’s Underground division, said: “This is a true milestone achieved for our industry where Epiroc in partnership with Orica have led the way to safer underground operation. By building on our recognised solutions and advanced Rig Control System, Avatel paves the way to safe productivity for the mining industry.”

Jari Näsi, Development Manager – Kittilä Mine, Agnico Eagle, said: “We are proud to create history here at Kittilä where the first mechanised and wireless development blast was initiated. There is always some risk when working close to the face; being able to do this work safely and efficiently from the cabin is promising, and mechanising the process will give a better blasting result.”

The first commercial implementation of Avatel will take place at Newcrest’s Cadia Valley Operations from December 2022.

Orica’s WebGen wireless initiation system helps unlock reserves at BMTJV Renison tin mine

The Bluestone Mines Tasmania Joint venture (BMTJV) says it has become the first company in the Tasmania mining sector to demonstrate Orica’s fully wireless initiating system, WebGen™.

Since early 2021, BMTJV, the owner of the Renison tin mine, has been in consultation with Orica to implement the WebGen wireless blasting technology.

The first WebGen blast was successfully loaded in the Central Federal Basset (CFB_1458_5990_F4) section of the mine on June 13, 2022, with the first wireless blast in Tasmania successfully fired at BMTJV over the mine’s leaky feeder system on June 19.

Some 107 WebGen primers were loaded into BP4 (Block Panel 4) and “slept” for 14 days while BP3 was charged and fired, the company explained. Due to the geometry of the blast – and it being a high seismicity area – for B4 to be mined conventionally, a further 60 m of development would have been required to recover this ore.

The Orica WebGen system includes an i-kon™ plugin detonator, a Pentex™ W booster and a DRX™, which is a digital receiver comprising a multi-directional antenna and a battery that serves as the in-hole power source.

The Encoder Controller individually programs each wireless primer with its own unique encrypted codes. This encoder contributes to the inherent safety of the system, and programs each wireless primer with two codes, BMTJV explained. The first code is a unique group identity number for exclusive use at each mine and assigned to specified groups of primers which will sleep, wake and fire together. The second code is a ‘delay time’ specific to the wireless primer and blast design.

Mark Recklies, Chief Operating Officer – BMJTV, said: “WebGen has now been used to support continual safety improvements and deliver savings across the working mine.”

Orica initiates WebGen 200 wireless blasting trial in Canada

As Orica progress towards the full commercial release of its WebGen™ 200 wireless blasting initiation platform, another milestone has been recently achieved at Moose Creek Quarry in Canada.

The team loaded and fired the first production blast for WebGen 200 on a customer site, successfully blasting 130 units.

This successful blast is a major milestone in the readiness of WebGen 200 for commercialisation, according to Orica, representing the culmination of years of research and development across technology, marketing, commercial, supply and manufacturing teams.

It comes two months after the company unveiled the product at MINExpo 2021 in Las Vegas, USA.

Global Head – New Technology Commercialisation, Nigel Pereira, said: “I want to thank all those involved in the successful trial and the team responsible for the development of our second-generation patented wireless initiating system, WebGen 200.

“This moves us one step closer to commercial release, and with over 70,000 WebGen 100 units fired across 2,500 blasts, both Orica and the industry are eager to see the program progress.”

Engineered to deliver market-leading safety and reliability, WebGen 200 has been built with enhanced capabilities, security and versatility, delivering safety and productivity gains for today’s applications and ensuring it meets the extreme mining conditions faced by surface and underground customers pushing the boundaries of mining’s next frontier, Orica said.

WebGen 200 will be available in four product variants and include a wider range of booster weights, opening up new segments, applications and opportunities in both surface and underground mining. The complete product range now includes the WebGen 200 Surface, WebGen 200 Surface Pro, WebGen 200 Underground Pro, and WebGen 200 Dev.

Dyno Nobel’s CyberDet I underground wireless blasting tech hits the mark at Westgold’s Big Bell

Dyno Nobel says it has completed the first ever underground wireless detonator blast in Western Australia, using its ground-breaking wireless technology, CyberDet I®.

The blast, on June 1, 2021 at Westgold’s Big Bell underground gold mine, saw 34 CyberDet I detonators fired, producing “outstanding results”, including a well fragmented muckpile, the Incitec Pivot Ltd business reported.

Big Bell is a premier asset in Westgold’s Cue portfolio of mines (expected to produce 100,000-110,000 oz/y for Westgold over the long-term, underwritten by output from the Big Bell mine, Westgold says) and the blast was undertaken following approval from the Department of Mines, Industry Regulation and Safety.

Dyno Nobel Asia Pacific President, Greg Hayne, said the blast in Western Australia’s mid-west region was a significant milestone for Dyno Nobel’s wireless detonator offering.

“We are so pleased to be able to partner with Westgold on the first underground wireless blast ever in WA,” Hayne said. “The blast was a great success and it’s been really pleasing to hear Westgold’s feedback that it believes CyberDet I will deliver improved safety and efficiency.”

CyberDet I is designed to allow operators to work in a safer environment during the blast loading process. The technology also facilitates a shorter blast cycle, providing the potential to increase the number of tonnes mined.

“CyberDet I is Dyno Nobel’s through-the-earth wireless detonator offering, developed on the back of customers telling us it’s technology they need,” Hayne said.

Incitec Pivot Ltd Chief Technology Officer, Robert Rounsley, said CyberDet I highlighted the group’s commitment to advanced technology development.

“One of the key advantages of our wireless offering is its portable design,” he said. “The flexible nature of our communications antenna provides significant operational advantages for our users.”

The next step for CyberDet I will be further trials in Australia, with several customers already interested in the wireless technology, according to the company.

“We’re looking forward to showing more of our customers the benefits of CyberDet I.” Hayne said. “It is just one of our premium technology offerings focused on meeting the needs of our customers. We are proud of our customer partnerships which are creating innovative, practical improvements in safety, productivity and environmental performance.”

BHP Mitsui Poitrel becomes wireless blasting leader

BHP Mitsui Coal’s Poitrel mine, in Queensland, Australia, now holds the title of world’s largest blast using wireless technology after successfully completing the third blast in a trial series to test Orica’s WebGen technology.

The latest blast on October 13 saw 1.3 million cu.m of overburden shifted in a strata blast fired with 1920 WebGen 100 units across 534 holes, BHP Mitsui said.

Jayson Smeeton, Poitrel Mine Production Manager, said there were significant safety and efficiency improvements to be made by using the WebGen technology Orica is trialing, which features wireless in-hole primers initiated by a firing command that communicates through rock, water and air.

“Wireless blasting means we are able to really reduce our people’s exposure to dust in the pit, and eliminates the potential for misfires because they do not need to physically tie each hole in to the blast pattern,’’ Jayson said.

“Eliminating the need to tie in each hole also makes the process for loading explosives far more efficient, and less susceptible to wet weather delays, as the pit does not need to be shut down because of the potential risk of accidental ignition during thunderstorms.”

The first trials conducted in May and June were small shots to test the technology. The latest blast involved a more complicated strata blast, with the top and bottom decks of the shot fired at different times to maximise fragmentation, and preserve the coal below, according to the miner.

Further production blasts, including through-seam blasts are planned for the next 12 months, BHP Mitsui said.

Orica reaches electronic detonator milestone at Brownsburg facility

Orica, a leading manufacturer of commercial explosives and innovative blasting systems, says it has now produced 100 million electronic detonators out of its manufacturing facility in Brownsburg, Canada.

The milestone Electronic Blasting Systems (EBS) detonator rolled off the production line on April 30.

Orica, Vice President, EBS, Adam Mooney, said: “Reaching the 100-million-mark demonstrates our commitment to customers in delivering a high quality and reliable supply of innovative blasting systems.

“Our state-of-the-art Brownsburg facility produces the full range of EBS systems for surface and underground operations, including i-kon™, uni tronic™, eDev™ and the world-first wireless initiation system, WebGen™. These market-leading EBS technologies, combined with our technical expertise on the ground, is how we deliver value to our customers every day.”

Since the first generation EBS manufacturing in 2006 at Brownsburg, Orica has continued to make advances in initiation technologies, supporting customers to enhance productivity with larger blasts, achieve faster deployment and blast set-up for both small and large scale blasting, and improve overall fragmentation and vibration control, it said.

Orica said: “The safety and reliability of Orica’s EBS systems are the best in the industry, the products are designed to perform safely and reliably even under extreme conditions. This includes extreme events such as detonators being struck by lightning, which customers face every day around the world.”

Orica’s EBS detonators are specifically designed with multiple safety features which enable protection against high-voltage electrostatic discharge, which occur in lightning strikes. These safety features were highlighted recently when an i-kon III detonator (pictured) in the Hunter Valley region of Queensland, Australia, was struck by lightning. The in-built safety features of i-kon performed as designed and did not result in an un-intended initiation of the explosive column, according to the company.

Today, Brownsburg has expanded production to include WebGen technology in the mining industry. This wireless initiation technology is breaking barriers in the mining industry, according to the company, through elimination of exposure to high-risk activities and enabling new mining methods and blasting techniques capable of delivering faster loading cycles, lower cost of production and improved, more flexible blasting reliability and management.

“The system provides for groups of in-hole primers to be wirelessly initiated by a firing command that communicates through rock, water and air, removing constraints imposed by the requirement of a physical connection to each primer in a blast,” Orica said.

WebGen™ is a critical pre-cursor to Automation and Orica is proud to be leading the reimagination of the mining industry through digital, automated blasting with products and solutions like the BlastIQ™ Platform, a cloud-based digital platform designed to enable continuous improvement of blasting outcomes through insights and data integration.

Orica Vice President, Initiating Systems & Packaged Explosives Manufacturing, Leah Barlow, said: “The Brownsburg facility prides itself on being a safety leader in Orica, with an excellent focus on robust safety systems and a proactive view to managing risk. Our robust quality control procedures coupled with a strong working relationship with our critical suppliers enable us to deliver EBS detonators that ensure safe, precise and reliable fires around the world.

“This 100-million-mark milestone achievement is testament to the Orica commitment to safety, excellence and innovation and is as much an achievement to be shared with the local community for their support over the years.”

With the recent addition of a new EBS assembly line in Helidon, Australia, another key global manufacturing site for Orica, customers in the Australia Pacific and Asia region are now benefitting from a stronger and more efficient manufacturing and supply chain operation that ensures reliable and quality supply of EBS within the region, the company said.

Goldcorp and Orica looking at further WebGen applications at Musselwhite

Following successful trials of Orica’s WebGen™ 100 at the Musselwhite gold mine, Goldcorp says it is looking at further drill and blast geometries and mining methods using the wireless blasting initiation system at the Ontario mine.

Goldcorp said these blasting tests underground at Musselwhite indicate “a decisive step on the path towards full automation of drill and blast operations in the future”.

In 2016, in collaboration with Orica, Musselwhite began testing WebGen, a system which fires primers through hundreds of metres of solid rock. “The wireless system has been designed to fully integrate with a mine’s existing blasting systems and improves safety by removing people from harm’s way,” Goldcorp said.

The project was recently announced as an award winner, which recognised the development of the temporary rib pillar (TRP) mining method using WebGen.

“The TRP is a revolutionary mining method that uses WebGen technology to extract ore pillars that previously could not be recovered in underground operations,” Goldcorp said. “Using this new method, the main ore of the panel can now be blasted and extracted while the TRP holds back the waste rock backfill. The inaccessible pillars can be blasted, delivering reduced dilution, increased truck fill factors and improved overall productivity.”

The system tested at Musselwhite enables groups of in-hole primers to be wirelessly initiated by a firing command that uses an ultra-low frequency magnetic induction wave to communicate through rock, water and air, according to Goldcorp. “This removes constraints often imposed by the requirement of a physical connection (wires) to each primer in a blast,” the company said.

The magnetic induction wave is transmitted by an antenna at around 1,800 hertz, and received by disposable receivers in each borehole, according to Goldcorp. Each 51 mm-diameter, 320 mm-long disposable receiver has a tri-axis antenna array to receive the signal, supporting any blasthole orientation.

Goldcorp said: “Following the blast plan, each disposable receiver is encoded with the Group ID for its blast, and each detonator with a delay time, just prior to being loaded into the blastholes. A standalone Code Management Computer (CMC) – a tablet wiped of other software – is uploaded with a CSV file from Orica’s blast design software. The CMC assigns the encrypted firing codes and delay timing into a preload blast file. A handheld encoder takes the data from the CMC and encodes each disposable receiver and detonator.”

Three separate codes make up the Group ID, and all three must be received from the transmitter to initiate a blast, according to Goldcorp. First, a wake-up code activates the appropriate disposable receiver from sleep mode. Next, the activated disposable receiver receives an arm code, which calibrates and synchronises the units. Finally, following the mine central blasting protocol, the fire signal is sent, firing each detonator according to its programmed delay time. Other disposable receivers, having not received their wake-up code, remain dormant in their blastholes, ready for subsequent blasts.

Following these tests, further drill and blast geometries and mining methods using WebGen are being explored at Musselwhite, Goldcorp said.

Musselwhite’s Chief Engineer, Billy Grace, said: “Since starting the TRP trials with WebGen in late 2016, our level of comfort with the technology has reached a point that discussing possible wireless applications is an integral part of our mine planning process. The entire team is excited by the possibilities that WebGen opened up, and the new opportunities they are allowing for us to increase our productivity and safety.”

At Orica’s 2018 AGM, Alberto Calderon, Managing Director and Chief Executive Officer at Orica, called WebGen “the most exciting development our industry has seen since bulk explosives in the 1960s”.
