Sandvik reinforces underground mining safety focus with DSI Underground buy

Sandvik has signed an agreement to acquire DSI Underground, a global leader in ground support and reinforcement products, systems and solutions for the underground mining and tunneling industries, from owner Triton.

The OEM has agreed a purchase price of approximately €943 million ($1.15 million) on a cash and debt free basis, it said, adding that the company will be reported in the Sandvik Mining and Rock Solutions division.

Stefan Widing, President and CEO of Sandvik, said: “This acquisition is an important step in our growth ambition. DSI Underground’s track record of driving progress and safety in underground operations and its global reach will further strengthen our world-leading market position within mining and rock solutions.”

DSI Underground is present in 70 countries, with 22 production units situated close to end customers, according to Sandvik. The product offering includes bolting systems, injection chemicals and resin capsules.

Henrik Ager, President of Sandvik Mining and Rock Solutions, added: “With the world’s most extensive choice of ground support products and systems, DSI Underground’s offering is highly complementary and enables us to deliver greater value and safety to our customers. The deal gives DSI Underground access to Sandvik’s substantial R&D, global service and sales network, complements our growing aftermarket business and strengthens our leadership in underground mining and tunnelling.”

Michael Reich, CEO DSI Underground, said: “With our knowledge of ground support technologies, we can add a valuable and complementary offering to Sandvik Mining and Rock Solutions. On the other hand, we will benefit from the knowledge of the new group and Sandvik’s global customer network.”

DSI Underground has around 2,000 employees, with revenue for 2020 expected to be about €518 million ($631 million, excluding the four joint ventures that are part of the acquisition). The purchase price is approximately €943 million on a cash and debt free basis.

The transaction is expected to close by mid-2021 and is subject to relevant regulatory approvals.

Montana Tech puts Epiroc Swellex bolts to the test

Mining engineering students at Montana Technological University are testing bolt integrity when loaded using a Ground Support Pull Test Kit and Swellex bolts donated by Epiroc.

The Montana Tech mining engineering program provides students with education, access to cutting-edge labs and participation in leading research, Epiroc says. The school has the only on-campus underground mine education centre in the US and uses it to give students hands-on experience.

“Working with modern equipment is also an important part of preparing students for the workforce,” Epiroc says. For this, the Mining Engineering department often relies on donations from equipment manufacturers.

Students are testing how much load and deformation they can get from Swellex bolts without losing integrity. This test project began as a challenge from a leading mining corporation.

To help make the project a reality, Epiroc donated the Ground Support Pull Test Kit and Swellex bolts, with an Epiroc team led by Adrian Berghorst, Segment Business Manager – Ground Support, and Eric Ball, Northwest District Sales Manager – Rock Drilling Tools, providing installation and hands-on training support.

As part of the test, sleeves will be used on bolts to qualify the critical bond length of Swellex bolts under forced displacement without loss of integrity in the bolts. The Pull Test Kit supplied will be essential to testing the bolts’ load and deformation characteristics in that rock mass and borehole.

In addition to benefiting the students, the research performed also allows the school to publish their findings, Epiroc says.

Scott Rosenthal, Mining Engineering Department Head, Associate Professor, Mining Engineering at Montana Tech, said: “With access to this equipment, students can do something unique and different. We thrive thanks to the support of industry partners like Epiroc.”

Shawn Cheney, Epiroc Business Line Manager – Rock Drilling Tools, added: “Partnering with Montana Tech helps give the next generation of miners a great start, enables additional research on mining limitations and capabilities, and gives Epiroc additional insights so we can continue our ongoing quest for improvement in mining.”

Ground support, electrification, automation, digitalisation all part of MacLean’s PERUMIN 34 showcase

The upcoming PERUMIN 34 mining convention in Arequipa (September 16-20) is providing Canada-based mining vehicle manufacturer MacLean Engineering a chance to share its latest field data and learnings from product development efforts in the areas of ground support, electrification, automation, and digitalisation.

This includes face bolting, full-fleet battery electrification, tele-remote and driver assist vehicle operation, real-time vehicle monitoring, and virtual reality training.

MacLean’s participating delegation includes a full contingent of sales and product management specialists both from the MacLean Peru branch, in Lima, as well as from head office in Canada.

The company first established a branch in Lima in 2012 to provide technical and sales support to the local mining industry. Since that time, the company has grown its in-country staffing contingent to over 50 employees, including over 40 mining vehicle technicians who provide site-level service and support to mines throughout the country.

Peru is also the first international mining jurisdiction where MacLean has sold and commissioned its latest ground support installation option – face bolting on the 975 Omnia scissor bolter – with two units currently working underground for bolting the face within the underground mining cycle. At least one of these is at the Nexa Resources’ owned Atacocha zinc-copper-lead-silver-gold operation in the Peruvian Andes (pictured).

MacLean President, Kevin MacLean, said the company’s Lima branch is at the heart of its commitment to underground mining, not only in Peru but also across South America.

Tony Caron, MacLean’s Vice President of Latin America, Quebec and Nunavut, said: “Our approach in Peru has stayed faithful to our approach to building a lasting business in other international markets, which is to establish local roots and take a long-term view, focusing on nurturing customer partnerships.

“From the Abitibi region of northwest Quebec to the nickel basin and gold mines of northern Ontario; from the Kivalliq region of Nunavut in the Canadian Arctic to Nevada, Sub-Saharan Africa, and Australia – in each of these unique mining geographies, geologies and cultures, the one constant is the importance of in-country service and support.”

MacLean’s Product Manager for Bolting, Stephen Denomme, said the MacLean bolter is the benchmark for ground support installation safety, productivity and versatility in Canadian hard-rock mines. “With our latest face bolting design, we are able to offer up to the mining industry in Latin America, a semi-mechanised bolting option where the operator is always working under protected ground, where you get best-in-class productivity for bolts and screen installed per shift, along with the versatility of multiple bolt-type installation and a deck configuration that allows for the storage of a full shift of consumables,” he said.

“This is the MacLean bolting approach and technology that we look forward to sharing with industry colleagues during the week of PERUMIN 34 in Arequipa.”
