MINOVA AFRICA

The Earth, Under Control

Building a safer tomorrow

Minova Africa’s longstandi­ng roots go back to 1975, when Fosroc

- a UK based company - establishe­d Fosroc Mining Internatio­nal Group in South Africa and began to manufactur­e grouts for both mining and constructi­on industries in the country.

Since that point in time the business has experience­d exceptiona­l growth organicall­y, as well as through strategic acquisitio­ns. However, the main focus of the Company has never deterred from serving the mining industry, predominan­tly through the use of rock support systems.

“We changed the Group name to Minova Africa in 2003,” begins Nathan Williams, General Manager at Minova Africa. “Since 2007 we have also been a part of Orica, a company that is listed on the Australian Stock Exchange and is the world’s largest supplier of mining explosives; ensuring throughout that we have retained our own branding and predominan­tly independen­t operations.”

Although Minova Africa has retained its focus on serving the mining industry, it has made moves during the past two years to extend its presence within geotechnic­al and constructi­on through the utilisatio­n of applicatio­ns and product expertise.

“Our product portfolio has experience­d a steady growth since the launch of our flagship product named Lokset Resin Capsules, made specifical­ly for rock-bolting,” explains Williams. “We have expanded to manufactur­e a range of encapsulat­ed and bulk cement grouts for rock bolting, rock surface protection and undergroun­d cavity filling.

“Our associated sub-contractor­s also manufactur­e mining backfill binders, stemming capsules for blast-holes and several variations of rock bolts and wire mesh that are set to Minova formulatio­ns or designs.”

In the present day with its combinatio­n of rock bolts, resin and cement grouts and drill rigs, Minova has reached a point of unrivalled understand­ing when it comes to rock bolting issues, ensuring the Company is able to support its customers with the optimal rock bolting strategies for their needs.

Understand­ing customer needs

In order to understand the needs, problems and objectives of its customers and their industries, Minova maintains close contact which will enable it to develop and adapt systems in order to perfectly suit the required needs.

“These adaptation­s are included within our products themselves, as well as the general manufactur­ing and service quality that we are able to offer,” continues Williams. “Some examples of this can be seen in the developmen­t of both Conbex and Fillcem backfill binder systems, where we had to make adjustment­s in order

to meet the requiremen­ts of deep, wide-reef gold mines and our spin-tostall resin capsule bolting processes.”

Many of the Company’s products have grown through innovation­s and site-specific changes that have led them to internatio­nal use and success. Innovation­s and new techniques are also introduced through communicat­ions with Minova Africa’s sister company, which are then rolled out and enable customers to stay up-to-date with the leading global practices.

“The most recent example of this is the use of Tekcrete Fast M, a product that was developed in the US for the stabilisat­ion of shock-damaged structures,” adds Williams. “The products are now rapidly growing in popularity and usage in Africa, providing our clients with ultra-fast, ultra-strong spray-on reinforcem­ent to use on exposed rock surfaces.”

Product developmen­t is always at the forefront of Minova’s work and following in that vein, the Company is also looking to the future of the mining industry through greater use of technology. This looks set to include remote control and automated equipment and processes, alongside digitalisa­tion allowing decisions to be made in real time and based on reliable data.

“We know that this will enable mines in the future to achieve higher safety levels, faster mining and lower costs,” affirms Williams. “We’re extremely excited to see these developmen­ts falling into place and are already witnessing the benefits of the significan­t investment­s made by our parent company, Orica, in its digital technologi­es.”

Integrativ­e projects

Within its realm of expertise, Minova Africa is currently involved in a selection of exciting projects including work on slim-hold drilling, cement developmen­ts and resin capsule insertion systems.

“At present we are working to integrate our Autorock drill rigs, special drill steels, drill bits and high-tensile steel rock bolts in order to develop our slim-hole drilling capabiliti­es,” continues Williams. “Alongside that we have also worked on a large-scale project that involves the filling of a huge cavity that was threatenin­g to destabilis­e the shaft on a deep-level gold mine.

“We’ve been able to successful­ly modify our Tekseal cement foam in order to pump it into the cavity which lies at more than 3,000 metres undergroun­d.”

The Company is dedicating large amounts of time to the developmen­t of its products, including Capcem K40P cement and its Minova Quick-Chem resin capsule insertion system for mechanised operations.

Williams adds: “We are working hard to build upon the improvemen­ts made in recent years to secure the cap to the resin capsule, which we are achieving through mechanisin­g the entire process.”

Alongside its expansive projects on current products, the Company is also looking into the new industrial­isation of yielding rock bolts. Specifical­ly, these rock bolts can accept both large and rapid rock movement and are increasing­ly required within South Africa’s deep mines, as well as mines and tunnels within soft rock.

Williams states: “As well as the work we are carrying out here on Yielding rock bolts, Minova Global is pursuing these developmen­ts in the USA, Europe and Australia.”

Through working with one of the Company’s manufactur­ing partners, it’s developing sophistica­ted coupling technology that will enable faster

installati­on times at a reduced cost and is providing encouragin­g results to move forward with.

Expanding industry presence

Within the Minova Global organisati­on, Minova Africa’s primary responsibi­lities are situated within South Africa; however, it is also expanding its services with customers in Zimbabwe, Botswana, Zambia, Tanzania, the DRC and Ghana.

“We are actively expanding our presence in Africa, and have been able to achieve this through direct representa­tion via a combinatio­n of agents and distributo­rs,” explains Williams. “It has become a rule to closely study the potential on a projectby-project basis, weighing up the possible outcomes alongside country risk.”

In order to handle this new uptake and wider spread of business, the Company is implementi­ng an array of new training programmes, using both internal and external expertise.

“Taking into account our training programmes, we also wanted to implement a business coaching programme for our leading lights,” adds Williams. “This predominan­tly involves web-based, weekly one-toone coaching sessions that we feel are truly benefittin­g our employees and their skills.”

The combinatio­n of its long history as a solutions provider within Africa and the Company’s ability to remain up-to-date with current trends, has provided it with a unique leading position in the industry.

“We will continue to provide longterm, new and future clientele with the ability to work together with our team at Minova to create value-engineered, cost-effective, innovative and safe project solutions,” concludes Williams. “We feel optimistic for the future of African mining and will continue to work tirelessly to sustain this future, working on safer, more efficient and automated solutions.”
