As BME gears up to showcase its explosives and blasting offering to a Mining Indaba crowd in Cape Town, South Africa, that is encouraged by the global energy sector’s appetite for minerals, the company’s Managing Director warns that the mining industry is still focused on reducing its cost base.

The demand for minerals – many of which can be sourced in Africa – is good news for the future of mining, and will no doubt be an important focus at this year’s Investing in Mining Indaba, which runs from February 6-9.

However, the pressure on mines is still all about low-cost production, Ralf Hennecke, Managing Director of Omnia Group company BME, warns. This year, BME will be exhibiting at the event to showcase its mining and explosive solutions, including its flagship AXXIS Titanium™ electronic initiation system.

Hennecke is bullish about the positive impact of the energy revolution on mining, as there is widespread expectation that volumes of battery-related commodities will need to ramp up considerably. Efforts to decarbonise the world economy are relying on energy technologies that are mineral-intensive, he explained.

“The average amount of minerals needed for a new unit of power generation capacity will grow by 50%, according to predictions by the International Energy Agency,” he said. “This is because solar photovoltaic plants, wind farms and electric vehicles generally require more minerals to build than their fossil fuel-based counterparts.”

The typical electric car, for instance, requires six times the mineral inputs of a conventional car, and a wind plant requires nine times more mineral resources than a gas-fired plant. This quickly translates into considerable demand growth in certain minerals.

“In terms of lithium, the largest consumers are now electric vehicles and battery storage applications,” he said. “It is expected that these applications will also be the largest consumer of nickel within less than 20 years.”

While this is good news for Africa, where many battery minerals will be sourced, the continent’s mining sector will always need to be globally competitive, BME says. This means efficiency across the mining value chain, rooted in on-mine productivity and safety.

“As an early-stage activity in the mining cycle, BME recognises the importance of blast design and execution in laying the groundwork for optimal operations,” Hennecke said. “Our technology developments including AXXIS™ and other digital innovations allow quality blasting that raises productivity in energy-intensive phases such as loading, hauling, crushing and milling.”

Only by optimising efficiencies can mines achieve a place in the lowest cost quartile of producers, which in turn enhances their commercial viability and makes them less reliant on commodity price cycles, BME says.

“Given the cyclical nature of the mining industry, Africa’s mineral producers can build a long-term future for the sector by remaining sustainable even through the dips in the cycle,” Hennecke said. “There is a depth of experience and technologies, developed right here on the continent, that can help put them in that advantageous position.”

The AXXIS Titanium system being showcased at Mining Indaba has been trialled and tested in various global mining destinations and conditions.

Blasting and explosives leader BME hits safety milestone with zero RCR

After five years of steadily implementing its Safety for Life brand, Omnia Group company BME says it has successfully achieved one of its key safety targets – a zero recordable case rate (RCR) – for the year ending January 2023.

“We consider our zero RCR over the preceding 12 months as a proud landmark to have reached, based on the positive safety culture that our Safety for Life initiative has fostered within the business,” Ramesh Dhoorgapersadh, General Manager for Safety, Health, Environment, Risk and Quality at BME, said.

The RCR is based on the number of safety incidents which resulted in treatment beyond first aid.

Dhoorgapersadh highlighted that BME’s achievement has its foundation not only in sound policies and systems, but in the committed and practical application of these principles every day.

“Companies’ systems and processes often look very good at face value, but these need to be effectively translated into action,” he said. “A RCR of zero does not happen overnight and requires constant reinforcement from the highest level before it forms part of the prevailing culture in the workplace.”

He explained that BME’s safety protocols were driven by a range of safety interventions. These included working on visual felt leadership, process safety, near-miss reporting, driver awareness programs and fatigue management.

BME Managing Director, Ralf Hennecke, re-emphasised the importance of ‘leading from the front’.

“Visual felt leadership has been vital in helping to embed the culture of safety in BME,” he said. “This means a daily commitment by senior executives to focus on how safety plans are being applied on site.”

He noted the corporate alignment of BME’s efforts with the Omnia Group’s vision of zero harm and positive impact through responsible business practices. These frameworks also aligned with the stringent standards of mining customers, many of whom are major global players.

Dhoorgapersadh said the zero RCR was not an end point in the safety journey. The challenge of safety, he explained, was to continue finding ways to improve – thereby steadily reducing any risk of incidents.

“In recent years, for instance, BME has placed growing focus on the medical wellness of our employees,” he said. “They often work under very stressful conditions – frequently out in the open or on the road. Our medical surveillance programme has become more intense, to ensure that their physical condition is optimal at all times.”

This intervention also included subcontractors, especially in the transport sector, to ensure that similar attention was paid to the health of all drivers. He said BME’s focus on safety extended beyond people to the natural environment as well. The effectiveness of safety protocols had also contributed to the occurrence of no chemical spillages that could have an environmental impact.

“We are very aware that, to sustain our enviable safety record, we need to be revisiting all aspects of our progress to look for ways to refresh our approach,” he said. “An important aspect of safety management is about doing the simple things better and better. In every task, you need to be identifying where the risks are – and find ways of preventing those risks from becoming reality.”

BME supports industry skills development with new graduate program

A two-year graduate program has been launched by Omnia-group company BME to, it says, address youth unemployment and skills shortages in an evolving mining industry.

The program targets various disciplines in engineering and science – including mining, chemistry and microbiology, as well as skills in the fields of safety, health, environment and quality assurance. This is part of the commitment by BME’s leadership to support skills development and the growth of young people within the mining industry. The initiative is also instrumental in attracting and retaining talent for the company, it said.

Announcing the initiative, BME Managing Director, Ralf Hennecke, said that many businesses in industry require work experience, and graduates are often overlooked as they do not have the necessary skills or the understanding of the work environment to fill the role.

“Coupled to this, some graduates consider the work environment to be daunting,” Hennecke said. “We, therefore, believe our role will be to ensure that each graduate on our program is provided with the opportunity to grow and develop and reach their full potential. It is vital that we invest in skills development of the next generation of people who will drive the mining industry in the future.”

BME has recruited 19 graduates and placed them at various underground and surface mining sites where the company is currently active. Some graduates have also been placed at BME’s Losberg emulsion plant and its AXXIS™ initiation system plant.

BME Human Resources Manager, Tebogo Seakamela, said: “In a country like South Africa, it is crucial to train graduates without prior work experience, and this is what BME aims to do. Skills development and bringing new entrants into the sector is critical in growing our economy and the mining sector, which is still one of the largest contributors to the country’s gross domestic product.”

She noted that BME prioritises the nurturing and development of young talent, highlighting that these graduates gain immeasurable knowledge and understanding of the real world of work while on the program, ultimately preparing them for the workplace.

“Due to their resilience, agility and bold characters, our graduates have remained committed to the program,” she said.

As a trend in the market, most locally trained graduates are also recruited into other countries after having completed a graduate program – including those around Africa. “This is commendable and a testament to the calibre of our South African mining graduates,” she said.

She highlighted that while the graduates were from various universities across the country, the majority were from Wits Mining Institute at the University of the Witwatersrand in Johannesburg.

The industry is also evolving in terms of minerals extraction, she said, noting that with the introduction of automated and artificial intelligence-based mining, the graduates will get first-hand experience of these technologies being used in the workplace.

“We are building the skills for the future, as well as ensuring that we cultivate a learning culture that encourages and enables critical thinking and innovation,” she noted. “At the same time, these graduates are offered diverse career path options.”

Mampe Mogale, a Mining Engineering Graduate currently based at a mining operation in the Northern Cape, noted that BME held a two-day induction for all its interns across various disciplines at the beginning of October.

“The aim was to familiarise us with the company structure, various disciplines and the people responsible for certain roles within the organisation,” Mogale said.

Clement Marilela, a Mechanical Engineering Graduate, explained that BME made his transition into the company as smooth as possible, informing the graduates about the organisation, while helping them realise the “incredible opportunity” they have been offered.

“It was great to be given the chance to interact with and learn from some of the organisations’ leaders as they shared their expertise and passion for the business,” Marilela said.

Hennecke concluded: “BME is proud to play its part in cultivating the future workforce, preparing them for the field of work. South African graduates are talented and, with on-site experience, can be gainfully employed.”

BME’s AXXIS Silver electronic initiation system passes the test in Lesotho

High in the mountain kingdom of Lesotho, explosives and blasting specialist BME recently achieved the first blast outside of South Africa with its new AXXIS Silver™ electronic initiation system.

BME, a member company of the JSE-listed Omnia Group, is assisting a diamond mine customer to conduct quality blasts in all weather. According to BME’s AXXIS™ Support Manager, Hennie du Preez, BME has been active on this mine since 2016. Located at an altitude of over 3,000 m, the operation frequently experiences snow and sub-zero temperatures.

“This means blasting under challenging conditions, including extreme cold, snow and ice,” du Preez said. “BME provides everything from the emulsion explosive to the detonation equipment, which all continues to function well under these conditions.”

The AXXIS Silver initiation system employed at the mine is a leaner version of BME’s flagship product AXXIS Titanium™. The company conducts the priming, logging and firing of the blasts, and ensures a regular supply of emulsions to the site.

“Among the benefits of AXXIS Silver is its thin, copper-cladded downline wire, which de-coils easily for use in small diameter holes – even when they are waterlogged,” Du Preez said. “Due to their robust quality, our electronic detonators were able to remain in the holes for two days before blasting, in temperatures below zero where the hole collars froze solid.”

Despite the conditions, there were no issue encountered with the wire or the connector. BME’s latest logger, the TDC 600, also performed as normal in these cold and wet conditions, with no signs of screen lagging. Its battery lasted the entire duration of the logging and the firing of the blast, according to the company.

“We kept our blasting boxes in the vehicle until blasting time, and they switched on without any problems,” du Preez said. “Neither did the cold conditions cause any sluggishness of the screens.”

He confirmed that firing the blast went ahead as planned, with smooth communication between the logger and the blasting boxes. In the final communication check, there was no instability detected.

“This was another confirmation of the resilience of our system in cold climates and freezing weather,” du Preez said. “We have had AXXIS successfully tested in the US for operating in temperatures below minus 40°C, in anticipation of growing business opportunities in the US and Canada.”

AXXIS Silver allows up to 1,800 holes to be detonated in a single blast, initiated from two blast boxes linked.

du Preez noted that mines are increasingly asking for larger blasts to reduce downtime from pit stoppages during blasting. BME is expecting to apply AXXIS Titanium at the Lesotho operation, which can raise the number of detonators in a single blast to 20,000 – or 20 blast boxes firing up to 1,000 detonators each.

An added benefit of the copper-cladded wire, du Preez said, is that the steel wire responds to a magnetic field. After a blast, this allows remnants of wire in the blasted material to be removed by magnetic separators on the conveyor belts before entering the crushing and milling phases. It, thus, prevents potential damage to comminution equipment and contamination of mined material.

BME has also been supplying various Lesotho mine with up to 500 t of emulsion explosive each month. This involves the monthly movement of over 15 tankers through steep mountain passes to keep them supplied with fresh emulsion.

Another South African record for the largest electronic detonator blast has been broken by the blasting and explosives company BME.

The blast was conducted by BME, an Omnia Group company, at the end of 2020 at a manganese mine in South Africa’s Northern Cape province. Using its AXXIS™ electronic initiation system, BME was able to plan and execute a blast of 4,647 detonators. Just a few months earlier, the company had broken a previous record at the same mine by initiating 3,780 detonators in a single blast.

“The latest achievement involved a remarkable 535 t of emulsion explosive in over 2,300 blast holes requiring a total of more than 37,000 m of drilling,” Kobus Boonzaaier, BME Area Manager in the Northern Cape, said. “The resulting blast was able to move almost 2.3 Mt of rock within a matter of seconds.”

Boonzaaier highlighted that the advantage of these large blasts is that they allow mines to blast less often; this means less disruption and a more streamlined operation. The size of the blast was not the only factor to consider, however, as a quality blast must also optimise key outcomes like fragmentation, BME said.

“We were pleased to once again achieve good fragmentation with this blast, ensuring that the resulting particle size would facilitate efficient loading, hauling and comminution by the mine,” Boonzaaier said.

The mine has made use of a full blasting service from BME for the past five years, with BME providing its expertise through a team of over 20 blasters, operators and assistants.

BME’s emulsion explosives – combined with AXXIS electronic initiation system, electronic detonators, blast planning software and other accessories – have been helping break records at South African mines for over a decade. It has conducted even larger blasts in Australia and Zambia in recent years – in the coal and copper sectors, respectively.
