Amalgamated Mining and Tunneling will carry Sandvik loaders, trucks, development drills and bolters to supply to customers in the Canadian market as part of a new alliance partnership.

Amalgamated Mining is an Edmonton-based company that supplies new and used equipment, equipment reconditioning, and parts for customers.

For over 30 years AMT has been an industry leader in providing creative options for equipment and parts to clients globally, according to Sandvik. With in excess of 300 machines in its inventory, AMT can supply clients with equipment requirements for a new mine or fleet expansions with various rental and finance options.

Sandvik’s underground mining equipment will be available to rent or on a rent-to-purchase basis from Amalgamated Mining and Tunneling under the new alliance partnership beginning in September 2021, the companies say.

“It was important that we partner with an OEM that has a diverse line of equipment with great support,” President of Amalgamated Mining Group, Tom Flanagan, says. “With Sandvik being an industry leader in equipment technology, it will allow us to offer more options to our clients.”

The company will now carry products like Sandvik’s DD422i (pictured), DD421, and DD212 development jumbos, DS311 and DS312 mechanised bolters, as well as a wide range of Sandvik’s loading and hauling equipment including popular i-series models like the LH517i loader and TH545i truck.

Sandvik’s recently released Dual Controls drilling package, developed in conjunction with Byrnecut Australia, will also be available from AMT. The package is available for DD422i and DD422iE development drills and permits operators to complete both standard face drilling and ground support.

Sandvik Canada Inc’s VP, Peter Corcoran, says: “This new partnership with Amalgamated will give Sandvik an expanded network to provide access to our technologically advanced equipment to a wider audience in Canada.

“Amalgamated has an existing network that nicely complements Sandvik’s and the customer service that Amalgamated is known for will make them an excellent partner to deliver Sandvik equipment to those customers; we are very excited to begin the journey with this organisation.”

Amalgamated will also offer used Sandvik equipment, refurbished with OEM genuine parts.

Redpath puts Australia’s first Sandvik DD212 into operation at Silver Lake’s Rothsay

Redpath Australia says it has taken delivery of the first Sandvik DD212 production drill in Australia, putting it into action at Silver Lake Resources’ Rothsay gold mine in Western Australia.

The DD212 is a single-boom, electro-hydraulic drill for mining development and production and has been highly anticipated in the Australian narrow-vein market, Redpath says.

Redpath Australia’s Plant Manager, Chris Riethmuller, said the contractor specifically needed a rig that could drill in a 2 x 3 m drive and was able to drill within 100 mm of each wall to minimise dilution and increase recovery.

“Sandvik Mining and Rock Solutions stepped up to the challenge to the extent of redesigning the boom configuration to accommodate the request,” he said. “We then challenged them further and requested a 12-rod carousel be fitted to both of the rigs we have ordered. Sandvik had a plan in the pipeline for this carousel but agreed to fast track the project for us.”

The carousel has not yet been fitted to the first machine working at Rothsay due to scheduling requirements but is due to arrive in June, according to Riethmuller, who said the company is looking forward to taking advantage of the increased safety and expected productivity gain this tool will deliver.

In January, Sandvik announced the introduction of the DD212 rig, an upgrade of the Sandvik DD210 development drill rig, which is designed for narrow-vein operations.

Redpath, back in April 2020, announced it had been awarded a contract to carry out underground mining services at Rothsay.

Sandvik advances narrow-vein drilling options with new DD212 rig

Sandvik Mining and Rock Solutions has introduced a new compact and intelligent single-boom electro-hydraulic drill for tunneling and mining development in narrow-vein drifts.

The Sandvik DD212 is an upgrade of the Sandvik DD210 development drill rig, and is designed for narrow-vein operations. It delivers both high level productivity and low cost of ownership, the mining OEM says.

Based on factory and field tests, the Sandvik DD212 delivers an up to 20% reduction in boom positioning time per face and a circa-15% improvement in drill penetration rate. Its 3% improved pull out ratio, meanwhile, can result in an up to 10 cm greater advance per face when compared with similar equipment.

The machine reached 93% mechanical availability during its mine site test period, accumulating 300 hours of percussion drilling within two-and-a-half months of operation.

“The drill provides great performance with net penetration rate, drill quality and rock tools improvements with zero drill rods jammed during the test period,” Sandvik added.

Among the new features are a drilling control system, the THC562, which provides torque control and reaming hole selection. This enables the DD212 to provide increased drilling performance, while reducing the wear on both the rock drill and rock tools.

The SB20i intelligent boom is used for accurate hole electronic positioning, which enables the precise and fast navigation of drill feed and tool, with automatic parallelism and instrumentation for hole angle measurements, Sandvik says. The boom offers a large face drill coverage from 6-25 m² thanks to the 1 m boom extension and the two narrow-vein type rotation actuators.

The development drill has an extended, 12 ft (3.7 m) TF feed rod, which optimises the advance/round, while its RDX5 rock drill provides a fast drilling cycle time and low operating costs.

The specific compact and versatile CFX telescopic feed, meanwhile, can retract from 12 ft to 6 ft (1.8 m), enhancing multipurpose operation in small tunnel sizes of 2.5 m x 2.5 m to 3.5 m x 3.5 m.

“The DD212 delivers accurate face drilling, cross cutting and bolting and enables mines to open smaller tunnel sections, reducing overbreak, dilution and drilling costs,” Sandvik says.

The company added: “The new DD212 brings operational safety and versatility for tackling different applications, precise electronic positioning, ergonomic operator interface and data monitoring, all leading to a superior pull-out ratio and reduced tool consumption, ensuring that the new DD212 delivers the best fit in narrow-vein drilling.”
