Miner fatalities dropped in 2018, ICMM says

The International Council on Mining and Metals (ICMM) recently released the 2018 safety data of its company members, which showed the industry suffered 50 fatalities last year.

“ICMM and its members are committed to strengthening health and safety performance and reducing operational fatalities to zero,” the ICMM said. As part of this commitment, ICMM publishes an annual safety data report of its company members. The full report, Benchmarking 2018 Safety Data: Progress of ICMM Members, is available here.

The 2018 safety data report, which collates the safety data of around 1 million workers and contractors, recorded 50 fatalities in 2018. This was a decrease from 51 fatalities in 2017 and 63 fatalities in 2016, the ICMM said.

Eleven of ICMM’s 27 company members reported no fatalities in 2018, compared with eight in 2017. These were: Africa Rainbow Minerals, Barrick, Freeport McMoRan, Goldcorp, JX Nippon, Minera San Cristóbal, Minsur, Mitsubishi Materials, Newcrest, Orano and Sumitomo.

The number of hours worked across ICMM’s members increased by 16% due to data being included from new company members, Minera San Cristóbal, Minsur, Newcrest and Vale, the ICMM said. While total fatalities dropped by 2%, the fatality frequency rate dropped 19% from 0.027 to 0.022 fatalities per million hours worked, the council said.

There was also a drop in the injury rate from 3.94 in 2017 to 3.41, despite an increase in the number of recordable injuries from 7,515 to 7,751.

Tom Butler, ICMM’s CEO (pictured), said: “ICMM and our company members are determined to eliminate fatalities from their operations. The single highest cause of deaths in 2018 was from mobile mining equipment which is why we are exploring collision avoidance technology in our Innovation for Cleaner, Safer Vehicles programme.”

The report findings include:

  • One fewer fatality recorded in 2018 compared with 2017;
  • Eleven member companies recorded no fatalities in 2017, an increase from eight in 2017;
  • Fifteen fatalities (30%) were caused by transportation/mobile equipment, four higher than the 11 fatalities recorded in 2017;
  • Nine fatalities (18%) were caused by fall of ground in underground mines, eight fewer than the 17 in 2017;
  • In the six years of safety data published by ICMM, fatalities have dropped from 90 in 2012 to 50 in 2018 and, in this time, the fatality frequency rate has dropped by 33% to 0.022 deaths per million hours worked;
  • Total recordable injuries increased from 7,715 to 7,751 although the frequency rate reduced from 3.94 to 3.41 recordable injuries per million hours worked, and;
  • Since 2012, total recordable injuries have dropped from 13,895 to 7,751 and the total recordable injury frequency rate has dropped by 33%.

The report also examines incidents by country. The highest number of fatalities (14) occurred in South Africa, where 400 million hours were worked. There were six fatalities in Chile and Ghana where respectively 281 million and 51 million hours were worked.

The highest fatality frequency rates were recorded in Hungary, Spain and Laos which each recorded a single fatality, the ICMM said.

This benchmarking report provides the safety data from ICMM companies for 2018 and does not include fatalities from the Brumadinho tragedy that occurred in January 2019.

Hindustan Zinc after improved safety, productivity with Epiroc’s Mobilaris solution

Hindustan Zinc, India’s only zinc-lead-silver producer, has selected Epiroc to equip its flagship Rampura Agucha mine with Mobilaris Mining Intelligence™ (MMI).

A decision support solution for mine safety and efficiency, MMI enables superior situational awareness and is designed to visualise and support mining operations in all its complexities, in real-time, Epiroc says.

Hindustan Zinc has introduced various technologies and innovations and has obtained success in enhancing safety, efficiency and exploration, according to Epiroc.

Back in 2017, the miner looked to automate many of its operations, acquiring Epiroc drill rigs, LHDs, haul trucks (including the MT65) and exploration equipment to be used in five of its mines in northwestern India. The automation and other high-technology features of the equipment were enabled through the common Rig Control System, with most machines are equipped with the telematics solution CERTIQ.

Following the latest MMI order, Sunil Duggal, CEO, Hindustan Zinc, said: “We are continuously making efforts to develop better, connected and intelligent mines. The partnership with Epiroc will support our direction to develop safer and more productive operations at Rampura Agucha mine”.

Ulla Korsman-Kopra, Global Business Manager, Automation and Information Management at Epiroc, said the company would support Hindustan Zinc’s operational (mining) improvement processes with the MMI solution. “The globally-acclaimed features will take Hindustan Zinc’s operations to the next level of performance gains,” she said.

The MMI portfolio features situational awareness, short interval control, including machine data integrations, and traffic awareness promises to get maximum productivity and efficiency out of a customer’s mine, according to Epiroc.

“Thanks to the openness and transparency of the MMI solution, integrations with mixed fleet machines, sensors and more will create the foundation for vital real-time analytics,” Korsman-Kopra said.

The system is expected to be operational during once the networking is up and running at the Rampura Agucha mine.

Rampura Agucha is the second largest zinc mine in the world, according to Hindustan, with production of 3.9 Mt in the company’s 2018 financial year. It has a zinc-lead reserve grade averaging 15.7% Zn+Pb, with total reserves of 46 Mt as of March 31, 2018.

The ongoing underground mine project is being developed with a vision of producing 5 Mt/y of ore and includes a main production shaft of 955 m depth, 7.5 m diameter and hauling capacity of 3.75 Mt/y; two ventilation shafts, two declines from surface and paste fill plants, according to Hindustan.

BMA achieves ‘Australia coal first’ with shuttle car proximity detection trial

The team at BHP Mitsubishi Alliance’s (BMA) Broadmeadow coal mine, in Queensland, Australia, have been looking at ways to use proximity detection technology to reduce the potential exposure and risk to its people while working underground, and has recently achieved an Australia first for coal.

Glenn Owens, Project Manager, and Dave Zanette, Project Execution Lead, brought together a team of experienced electricians and engineers, and using the knowledge of its operators, began trialling proximity detection in Broadmeadow’s underground shuttle cars.

“Shuttle cars are considered to be one of the more higher risk pieces of equipment in underground mines as they are used to transport coal from the development face to the coal clearance system,” BHP said. “This machinery can unload hundreds of tonnes of coal per shift and are critical to the mine’s operations.”

After many months in planning and development, the team launched an Australian first for coal – rolling out the first ever Proximity Detection Shuttle Cars in full auto and stop modes.

“Keeping our people safe is always our highest priority so implementing this technology is a huge step forward in the future of underground mine safety,” Zanette said.

“It opens up the opportunity for us to use the technology across multiple pieces of mobile equipment and, if implemented correctly, can impact human behaviours in a positive way.

“It also has the potential to be replicated across all of our BHP underground and surface assets and throughout the broader industry, ultimately making mining safer for our people.”

The Proximity Detection System uses low frequency magnetic field generators, which are installed in the Shuttle Cars. The magnetic fields can detect two zones – Zone 1 (Warning Zone) and Zone 2 (Danger Zone).

When a pedestrian is detected in the Warning Zone, the machine will automatically slow down and the operator and pedestrian are both alerted via flashing orange beacons and alarms on the vehicle and cap lamps (worn on each person’s helmet).

Once someone enters the Danger Zone, a red flashing beacon and alarms sound and, importantly, the machine automatically stops, BHP said.

“Unique to an underground mining environment, there’s moving machinery, noise, limited lighting and confined spaces, so it’s fantastic to know that this technology provides an engineering solution on top of the existing controls to help keep our people safe,” Zanette said.

The project is currently in trial phase, with two of Broadmeadow’s shuttle cars already fitted with the system. All shuttle cars in Broadmeadow mine’s development panels are on track to operate the system by the first quarter of BHP’s 2020 financial year.

The Project Team will be testing this technology on Broadmeadow’s other mobile equipment such as personnel transporters, LHDs, shield haulers and selected surface mobile equipment, it said.

Ericsson and Ambra expand 5G partnership for mine automation

Ericsson and Ambra Solutions have announced a global cooperation agreement to lead automation for the mining industry, providing 5G-ready network solutions to automate ventilation systems, real-time personnel and vehicle tracking, and remote control of machinery like LHDs, haul trucks, drills and other mining equipment.

Ambra has selected Ericsson as a radio partner of choice, with the 5G-ready Ericsson Radio System portfolio enabling Ambra, a turnkey engineering services systems integrator, to simplify network deployments and replace up to 60 Wi-Fi access points with a single Ericsson solution, it said.

Eric L’Heureux, CEO, Ambra Solutions, said: “We are excited to expand our partnership with Ericsson to a global footprint. The Ericsson products are optimal to deliver the most demanding applications used by the mining 4.0 industry. The reliability of Ericsson products enables more predictable, secure and lower-cost connectivity, and mining companies want to use a reliable product that is available worldwide.”

Mission-critical Private LTE, deployed for Ambra’s mining customers, provides new capabilities and possibilities to cost-effectively enable digitalisation of mining-related tasks for open-pit or underground mines, Ericsson said. “Prior to this modernisation, specialised tasks and applications were difficult or simply impossible to achieve across the entire mining coverage area when using legacy ‘leaky cable’ or Wi-Fi connectivity.”

Shannon Lucas, Head of Customer Unit Emerging Business for Ericsson North America, said: “The global mining industry has been vulnerable to challenges of energy consumption, equipment loss, and human safety. We have designed an easy-to-use cellular connectivity solution to address these issues and deliver efficiency through digital transformation, while creating a path to 5G.

“Ambra will sell this solution as part of its portfolio and will partner with Ericsson customers (global service providers) to deliver it, which opens up exciting new opportunities and revenue streams for the service provider.”

Ericsson and Ambra partnered last year to deliver the world’s deepest underground LTE network for the Agnico Eagle mining complex, LaRonde Zone 5, in Abitibi, Quebec, Canada. Located 3.5 km below the surface, the mission-critical private network provides data and voice services across the LaRonde mine site and enables several internet of things (IoT) use cases to improve safety and mining operations. Since then, several applications have been deployed using Ericsson solutions to deliver automation of ventilation systems, real-time personnel and vehicle tracking and remote controlling of machinery like LHDs, haul trucks, drills and other mining equipment.

Agnico said recently that it was looking to expand this 5G network in the ramp area from level 269 to surface and at LaRonde 3.

Schauenburg launches artificial intelligence camera for mine safety

Schauenburg Systems says it has partnered with dotNetix to deliver an artificial intelligence-equipped camera to improve safety at mine sites.

The South Africa-based original equipment manufacturer (OEM) for mine-industry safety and productivity solutions said this will enhance its existing proximity detection system (PDS) range.

The SCAS PDS Artificial Intelligence Camera is an advanced driver assist system (ADAS), which is the first South Africa developed and manufactured camera with artificial intelligence specifically designed for mine safety/traffic management, allowing for event and video logging.

It has been identified in the mining environment that there are certain scenarios where tag-based PDS systems are not practical. For these scenarios, object detection systems are required that use passive PDS sensor technology, according to the company.

“This technology, in layman’s terms, is when a vehicle PDS system can detect and warn a driver of other objects without having any active PDS equipment installed on these objects,” Schauenburg Systems said. “There are many passive sensor technologies that assist tag-based PDS systems or act as standalone PDS systems. Schauenburg’s AI Camera stands for high accuracy, reduced false alarms, distance detection and data/video logging capabilities for effective incident analysis.”

This camera, specifically designed for the harsh mining environment, combines 3D-image processing with AI integrated into camera systems. The system uses advance algorithms to detect objects; depending on the risk profile the cameras are positioned in front, rear or on the sides of the vehicle, the company said.

“The potential of a collision is analysed by the system and the driver is warned with an audible alarm and/or voice command. The 3D cameras were designed to accurately calculate the distance to an object by means of configurable dynamic zones of up to 150 m,” Schauenburg said.

Ettiene Pretorius, Business Manager at Schauenburg, said although the product is designed at this stage specifically to fulfil mining PDS requirements, it is evident there are many other applications where this product can assist in automating operations. “Schauenburg and dotNetix are excited about the official launch of this product, after the product went through stringent test, trial and certification phases which were part of the industrialisation process,” the companies said.

Dieter Kovar, CEO of Schauenburg International-Africa Group, said Schauenburg’s vision is to innovate new products through latest digital technologies and by ingraining a customer-centric culture.

“In line with the latest Mining Charter it strives for developing and manufacturing products primarily in South Africa. It considers itself as a prime partner for supporting the digital drive in mining,” he said.

Sandvik LHDs and dump trucks open to third-party proximity detection systems

Sandvik Load and Haul says it has developed a Proximity Detection System Interface for its underground LHDs and dump trucks.

The feature allows installation of a third-party proximity detection system (PDS) to a Sandvik underground loader or dump truck to meet legal requirements and improve safety in underground operations.

“PDSs help to improve safety at mine and construction sites where risks of collision may occur,” Sandvik said. “The PDS is generally designed to slow down and/or eventually stop the equipment in case the system detects a person or an object carrying a tag inside a predefined zone. The exact operation of the PDS always depends on the selected system and the local conditions, which vary from site to site.”

Marjut Seppälä, Product Safety Manager, Load and Haul, said: “A PDS is a legal obligation in South Africa, which is an important market area for Sandvik. We have developed the interface to meet these requirements and, at the same time, to improve safety on our customer sites. As we want to provide the same opportunity for all our customers, regardless of the market area, the interface now becomes globally available for our loaders and trucks.”

She continued: “But even though PDSs help to improve safety, they shall never be used to replace normal safe and sound operating practices.”

The PDS interface comes together with another safety enhancing feature, Speed Brake Interlock, which is used to prevent excessive speed during driving. When the Speed Brake Interlock functionality is in use, it monitors the equipment speed and guides the operator to slow down by means of visual and audible messages on the system display.

Barminco and Independence Group establish Technology Development Committee

Barminco Holdings and Independence Group have established a Technology Development Committee at the same time as the two agreed to extend the services contract at the Australian miner’s Nova nickel-copper-cobalt operation in Western Australia.

The committee’s aim is to identify and implement innovative methods and technologies to advance safety and productivity in underground mining. According to Barminco Chief Executive Officer, Paul Muller, this will initially target projects such as the early stage development of electric vehicles, enhanced mine control systems, machine vision and proximity detection.

In the meantime, a four-year contract extension for underground mining services at Nova will see Barminco pocket some A$240 million ($170 million). There is an option for a two-year extension within the contract.

Muller said Nova was an important project for the company, with Barminco delivering 29 km of development and extracting 2.4 Mt of ore since development started in 2015.

“Barminco has supported the Nova project’s transition from development, starting with excavation of the box-cut on Australia Day 2015, to production, delivering a successful first year of commercial production in the 2018 financial year.” The 2018 financial year saw the operation produce 22,258 t of nickel and 9,545 t of copper.

Muller added: “We now look forward to working closely with IGO under a formal arrangement to drive further productivity and safety improvements at Nova.”

Peter Bradford, IGO’s Managing Director and CEO, said: “Barminco has been an important partner in the development of Nova. With the majority of the capital development completed at Nova there is a focus on incremental operational and productivity improvements associated with stope mining activities.

“The four-year term, with the option to extend by two years, allows us to work together to unlock this value.”

He added that both companies are committed to mapping and implementing these productivity improvements through new technologies, with the establishment of the technology committee representing an important step towards this objective.

Just last week, Barminco, which is in the middle of being taken over by Ausdrill, was awarded two four-year contracts at Gold Fields’ Agnew gold mine in Western Australia.

On the same day the Nova contract extension was announced, Ausdrill confirmed its shareholders had signed off the deal for Barminco. The offer values Barminco’s equity at A$271.5 million. The deal is now expected to be completed by the end of the month.
