Epiroc says a large fleet of battery-electric mining equipment will be deployed at Assmang Proprietary Ltd’s Black Rock underground manganese mine in the Northern Cape of South Africa after the two companies signed an agreement.

Assmang has ordered several of Epiroc’s battery loaders and mine trucks – the Scooptram ST14 Battery and Minetruck MT42 Battery, respectively – for the deployment. The order was booked in the March quarter of 2022 and is valued at SEK120 million ($12.5 million).

The order extends Assmang’s and Epiroc’s collaboration to use state-of-the-art solutions for optimised operations at the mine, Epiroc said. Assmang has previously ordered the same type of battery-electric machines for this mine, and, in 2019,  selected Epiroc’s Mobilaris Mining Intelligence digital solution, which provides superior situational awareness of the mining operation in real-time

“Epiroc is proud to support Assmang on its journey toward lower emissions through the use of our cutting-edge battery-electric machines, while also prioritising productivity and safety,” Helena Hedblom, Epiroc’s President and CEO, said.

The Scooptram ST14 Battery and Minetruck MT42 Battery machines, manufactured in Örebro, Sweden, are built to face the toughest conditions and are packed with intelligent features, according to Epiroc. They will be equipped with a Collision Avoidance System as well as with the telematics system, Certiq, which allows for automated monitoring of productivity and machine performance.

PYBAR sets records at Glencore’s Black Rock mine with Sandvik DL432i longhole drill

The introduction of PYBAR’s new Sandvik DL432i longhole drill in October 2020 has led to month-on-month improvements in drilling productivity at the Black Rock copper-lead-zinc mine, in Queensland, Australia.

Versatile and compact, the Sandvik DL432i is a fully mechanised electro-hydraulic top hammer longhole drill, designed for large-scale mining. The Sandvik iSOLO drilling control system allows the client (Glencore in this case) to provide electronic drill plans on a USB, which is plugged straight into the drill. The operator then lines the drill up on the survey markings and selects the required drill design, with the remainder of the drilling taken care of by the iSOLO software.

Since arriving on site, a specialised pump has been installed on the DL432i, allowing AMC (a subsidiary of IMDEX) to add a Bore Hole Stabiliser™ to the water circuit while drilling to improve hole integrity in the soft ground conditions. This technology, combined with Sandvik’s iSOLO drilling control software, has been key to PYBAR’s production success at Black Rock to date, the contractor said.

“The ground conditions at Black Rock have put Sandvik’s iSOLO drilling control system to the test, and the technology has proven itself with flying colours,” PYBAR said. “After several months of on-site refinement of the automated drilling system, the drill can now operate with minimal operator input.”

This has led to month-on-month increases in production drilling rates with a record month in March, closely matched in April, according to PYBAR. This, in turn, has meant a significant increase in available production fronts resulting in increased tonnes and improved overall project performance.

Trials of automated drilling for complete firing patterns will begin shortly at Black Rock to enable drilling to take place during firing and shift change, as well as free up the operator to assist with other tasks around the mine, PYBAR said.

The transition to further automation has the potential to significantly maximise both productive drilling time and overall performance for the project, it added.
