Epiroc has introduced the DM30 XC blasthole drill for a variety of multi-pass rotary and down-the-hole (DTH) drilling applications, offering, the company says, 33% more power and many benefits to customers.

Built off the same platform as the Epiroc DM30 II, the DM30 XC is designed for maximum productivity and efficiency due to increased rotary torque, increased pulldown and a larger hole range capability. The DM30 XC is built to handle a 101-159 mm drill pipe and has a weight on bit up to 20,000 kg. The heavy-duty, crawler-mounted, hydraulic top-head drive drilling rig features a 9.1 m drill pipe change and a standard carousel.

“The DM30 XC is built tough for the most demanding jobs, and high quality at an excellent value is what sets it apart from other drills in its class,” Mark Stewart, Regional Business Manager, Epiroc Surface division, said. “The drill is designed for mining so the structural components will hold up to the heavy-duty cycles required in a mining drill. The robust frame and tower weldments are manufactured to last the lifetime of the machine.”

With a starter rod under the rotary head, the DM30 XC can achieve a total clean depth capacity of 45.1 m for multi-pass applications and 8.5 m for single-pass applications. High efficiency and a 1,136 litre fuel tank allow the rig to run for up to 16 hours before needing a refill for continuous operation. In addition, the smaller, compact footprint of the DM30 XC makes it easy to manoeuvre on tight benches and simple to transport over between pits.

No matter the customer’s need, the DM30 XC offers options to suit any application, according to Epiroc.

Customers can choose a low- or high-pressure compressor to create the right configuration for their drilling operation. A one-piece FOPS (Falling Object Protective Structure) rated cab with electric over hydraulic controls offers enhanced safety, visibility and operator comfort. The DM30 XC is easy to operate, especially for drillers who have experience in other DM series machines. The ergonomic controls layout allows immediate switchover from drilling to tramming mode, maximising time available to drill.

The DM30 XC is equipped with an Electronic Air Regulation System (EARS) that provides low load start up and easy adjustment of bailing air to save horsepower and lower fuel consumption, extending power component life and decreasing total cost of ownership.

Customers can add even more flexibility to their DM30 XC with Epiroc’s Rig Control System (RCS) Lite, which offers several safety and productivity features. It also provides a convenient foundation to add more functionality and technology options in the future without a major rebuild of the machine, Epiroc says.

RCS Lite allows all Epiroc rotary drills to have the same on-board display and system for consistent operator training and service. The modular RCS Lite solution offers customers three different packages to choose from.

Collar Keeper System exceeds expectations in latest Western Australia field trial

Explosives and blasting, Mining equipment, Mining services, , , , , ,

Aquirian Limited says its wholly owned subsidiary, TBS Mining Solutions Pty Ltd, has completed the final in-field trials of its Collar Keeper® System.

The field trials were conducted at a gold mine in the Mid-West of Western Australia, on a blasthole track rig in both wet and dry conditions. The trial included full production testing over the course of seven continuous shifts irrespective of ground conditions, it said.

Over the course of the trial, 254 production holes were drilled including 30 wet holes in difficult ground conditions where The Collar Keeper System eliminated the requirement for costly and time-consuming collar piping, according to Aquirian. In addition, the system achieved significantly reduced drilling time for the wet holes, seeing greater than 50% improvement in drill yield in these areas. Importantly, the system maintained full hole depth across all the holes removing the need for any re-drills.

“This post-drill hole quality represents a significant shift in operational benefit for the industry, removing costly rework in redrills and duplication of blasthole dipping throughout the drill and blast cycle,” the company said. “With the improvement in drill cycle times, drill yield and the elimination of re-drills experienced during the trial, it is expected the Collar Keeper System will make a notable impact on reducing CO2 intensity per drill hole produced.”

Just last month, TBS entered into a binding technology Memorandum of Understanding with MACA Mining Pty Ltd, a subsidiary of MACA Ltd, looking at collaborating on the development and commercialisation of the Collar Keeper System.

Greg Patching, Executive Director Business Development & Innovation, said: “We are again thrilled with the performance of our Collar Keeper System in a variety of typical drilling conditions. The system’s ability to improve overall drill time across the holes and, more importantly, deliver repeatable quality blastholes irrespective of conditions was fantastic.”

TBS has entered preliminary discussions with several clients for the Collar Keeper System with commercialisation to begin in the September quarter of 2022. The company is targeting implementation on 12-15 track rig units by June 2022, generating revenue of approximately A$125,000-$200,000/mth ($88,836-142,107) on an ongoing basis. The current commercialisation focus will target approximately 200 blasthole track rigs operating on mines (excluding quarries) in Western Australia alone, noting that thousands of these rigs operate on mines globally.

David Kelly, Managing Director, said: “This is a really exciting time for Aquirian as we work towards realising the commercialisation of the Collar Keeper System. It will not only make a step change impact on cost and quality for our customers, but it will also introduce a new and significant revenue stream for the company into the future.”

Aquirian buoyed by Collar Keeper System blasthole results in Western Australia

Aquirian Ltd says it has successfully completed the Stage II prototype trial of its Collar Keeper® System (patent pending), a technology designed to improve blasthole quality control across the mining sector.

The Stage II prototype unit was deployed on an existing drill rig operating in a hard-rock gold mining environment in the mid-west of Western Australia, according to Aquirian. The trial successfully tested fitment to existing drill rigs and delivered marked improvements to drilling rates and drill hole quality.

Drilling rates were improved by approximately two minutes per drill hole on a 5 m blast bench during testing, which equates to an improvement of more than 20% over conventional drill methods, the company claims. Further benefit in time savings as compared with a traditional collar piping process is expected to be realised during Stage III testing in December 2021, it added.

The prototype testing was conducted over numerous blast holes, testing system functionality and speed of deployment.

The Collar Keeper System is a combination of Aquirian-developed, retrofittable drilling apparatus combined with its existing Collar Keeper. The technology represents a step change in managing blasthole quality and is targeted to provide a unique solution to a range of different blasting environments with global applications, the company said.

The initial focus for the technology will be on mines operating in Western Australia with smaller-diameter holes in challenging ground conditions, where high-cost collar piping is traditionally used.

“The traditional method of collar piping has not changed in over 40 years and introduces significant hazards as well as cost, time and quality issues, and poor blast outcomes for clients,” the company said. “In addition, the poor blasting outcomes lead to further downstream costs in load and haul, and the processing of mined material.”

The current development focus is targeting around 200 operating drill rigs in Western Australia alone, pending the commercialisation of the technology intended for the 2022 financial year.

Aquirian Managing Director, David Kelly said: “We are excited by the successful trial of our Stage ll prototype last week. The system can be quickly and easily retrofitted to existing drill rigs and the improvements to drilling rates and blasthole quality exceeded our expectations. We will continue trialling the Collar Keeper System in alternate conditions with the aim of commercialisation over the current financial year.”

Epiroc has introduced the Automatic Bit Changer (ABC) for hands-free bit changes on Pit Viper 270 and Pit Viper 290 series drill rigs.

The ABC option is designed to change rotary tricone bits faster than manual exchanges and eliminates human interaction with the drill string for a safer way to operate a drill fleet, the company says.

It makes it possible to complete drill bit changes with a single touch of a button, according to Epiroc. This can be done from either a remotely based control room or in the comfort of the cab.

“The ABC option optimises productivity and efficiency of the drilling operation and improves safety by eliminating exposure to live work environments,” Epiroc added.

The ABC carousel can store three rotary tricone bits in varying sizes and cutting structure, for a total of four on-board bits, for flexibility and versatility on a drill site. Unique bit adapters allow the system to safely replace the worn drill bits with new fresh drill bits without exposure to live work.

Epiroc says the ABC is capable of completing a bit change in significantly less time than a manual process for decreased downtime. Time saved by eliminating manual drill changes increases machine utilisation and profitability.

“The Automatic Bit Changer is the next step in autonomous drilling advancements,” Tim Ledbetter, Vice President – Automation R&D, said. “The process of continuously evaluating how to move the industry forward is key to this innovation. We will eliminate live work for our customers with safer, more productive technology, machines and operations.”

Customising a Pit Viper 270 or Pit Viper 290 drill rig with the ABC option offers many benefits for the operator, Epiroc claims. It reduces the possibility of human error, injuries related to heavy lifting, lost time on manual adjustments and accidents.

Eliminating these Live Work tasks is crucial in the mining industry, with several options for Live Work Elimination available for a range of Epiroc equipment.

At the conclusion of field trials, the ABC will be available for new drills and retrofit of drills already in the field, Epiroc says.

Robit’s ‘built to last’ philosophy on show with newest products

Environmental, Explosives and blasting, Mining consumables, Mining equipment, Mining services, Steel and iron ore, Sustainable mining, , , , , , , , ,

Robit has launched two new products that, it says, have been designed to deal with the harshest mining conditions.

Its tubeless range of high-performance down-the-hole (DTH) hammers and the Robit Extreme Carbide are made for environments where wear and tear are a constant factor, the company says.

The new range of tubeless DTH WH TL hammers has been designed to eliminate the risk of foot valve breakages and the resulting operational downtime, according to Robit. Not only has the foot valve been removed to enhance reliability, but the design of the hammers has been further revamped to bring maximal usability in a minimal footprint, making them ideal for both blasthole and energy well drilling applications, Robit said.

The integrated choke system allows for airflow adjustments to suit the compressor and improve flushing, Robit says. The hammers’ inner liner allows optimal airflow and provides improved performance in wet conditions. The piston, itself, has been redesigned for improved strength and optimal performance. The hammers are suitable for ground conditions with high volumes of water or in soft unconsolidated ground, according to the company.

The Dual Property Extreme Carbide, meanwhile, is built to last.

Customer trials conducted in North America showed bit life improvements of over 50% when drilling in highly abrasive ground conditions, making it the ideal choice for blasthole and well drilling applications, Robit claims.

The Dual Property Extreme Carbide has a wear-resistant outer layer that uses the Robit Extreme grade #4 carbide. This is specifically formulated for highly abrasive ground conditions, staying sharper for longer while increasing productivity and reducing the number of necessary regrind processes. Furthermore, the Robit Extreme Carbide has been developed to reduce the overall CO2 impact of drilling and to improve the sustainability of Robit products, the company says.

Under the outer layer of wear-resistant Robit Extreme Carbide, the inner core is made of standard grade #1 carbide. This makes it strong and durable against fracturing, all the while guaranteeing the DTH bit performs at the same high level as Robit standard quality carbides are renowned for once the outer layer has eventually worn away. And for customers that do not re-grind drill bits, preferring to “drill-to-destruction” or “run-to-life”, the Robit Extreme carbide has shown to be even more advantageous, Robit says.

The recently-released Robit Rbit button bit series is also showcasing the company’s sustainability credentials. Made of 100% recyclable steel and finalised with eco-friendly water-based paint, the Rbit is designed to achieve the fastest rates of penetration and lowest cost-per-metre drilling in the company’s range.

All these products will be presented at the company’s MINExpo 2021 booth in Las Vegas, September 13-15.

Ausdrill says it has just commissioned the first of four new Caterpillar MD6250 drills at the Boggabri coal operations in New South Wales, Australia.

The machine has been successfully commissioned on site four weeks ahead of the contract start date, according to the Perenti company, with the help of the WesTrac team at Tomago, NSW.

These M6250 drills come with the next level of drill automation and driller assist, Ausdrill says, including one touch auto levelling and auto drilling functions combined with Cat MineStar Terrain for drilling to improve safety, productivity, reliability and accuracy.

Back in February, Perenti reported its Surface Mining Industry Sector Group had been awarded A$155.5 million ($113 million) in new and extended contracts. This included a three-year contract (with options to extend) for production drilling services with Boggabri Coal Operations (a part of Idemitsu Australia Resources Group) at Boggabri.

The MD6250 is designed for both down-the-hole drilling in hard rock and rotary drilling in softer rock. The blasthole drill carries out single-pass drilling and multi pass, as well as angle drilling, according to Cat.

MACA is currently running an MD6250 at the Bluff coal mine, in Queensland, while AngloGold Ashanti Australia, with support from Flanders and Tropicana Mining Alliance partner, Macmahon Holdings, now has five autonomous Cat MD6250 drill rigs as part of its drilling fleet at the Tropicana gold mine, in Western Australia. Thiess, Cat and WesTrac have also introduced an MD6250 drill rig with autonomous drilling capability at Mount Pleasant, in New South Wales, in a phased 12-month pilot project.

Mineral Resources Ltd says it has become the first company in Australia to start up Epiroc’s new generation SmartROC D65 drill rig.

The updated SmartROC D65 delivers high-quality blast holes with accuracy and precision and is loaded with smart features such as automated drilling and rod handling, according to the miner and technology and service provider. It also uses less hydraulic oil than previous versions and has fewer hoses and pumps. This helps to reduce costs and makes servicing easier, while increasing sustainability and reducing the environmental impact of the rig, Minerals Resources says.

Back in October 2019, Epiroc’s Kris Thomas, Product Manager – SED at Epiroc Australia, told IM that Australia was the first big target market for this new rig, with the new model already having been put forward in several major tenders, particularly in the Western Australia iron ore industry.

Mineral Resources’ own portfolio of iron ore assets comprises numerous known deposits and highly prospective targets across two of Western Australia’s premier iron ore provinces – the Yilgarn and the Pilbara.

“We decided to bring our drill and blast function in-house to enable greater agility, innovation and optimisation,” Mineral Resources said. “We’re always looking at ways to reduce our environmental footprint, not only with the work we perform but also in our choice of equipment.”

Having the new drill rigs on site allows for further efficiencies, the company says, as a platform drill is no longer required to drill up to 229 mm blastholes.

“By being more efficient in everything we do means we’ll continue to achieve our aim of being a leading provider of innovative and sustainable mining services and a low cost mining operator,” the company concluded.

Mining3’s ‘Top of Coal’ tech heads for commercialisation with CR Digital pact

Coal technology, Explosives and blasting, Mining services, Mining techniques, Steel and iron ore, , , , , , , , , ,

Mining3’s “Top of Coal” technology is heading for commercialisation after the company signed an agreement with CR Digital for the next phase of the innovation’s development.

The announcement comes on the back of promising new results delivered from the most recent trial in the Bowen Basin of Queensland, where the technology was tested over 12 weeks and collected downhole data from over 250-plus boreholes, the companies said.

“Accurately detecting the approaching top of a coal seam prior to blasting is fundamental to efficient coal recovery,” Mining3 and CR Digital said. “During the extraction stage, a significant percentage (up to 12%) of overall coal loss is attributable to blast damage and coal dilution, which then makes it difficult to separate the coal cleanly from the waste during both overburden excavation and coal processing. By eliminating the damage done to the top of seam, substantial increases in recovery are enabled.”

With support from ACARP, Mining3 has been developing a measurement while drilling (MWD) system that detects the top of a coal seam while routinely drilling blast holes.

During the drilling process, the detection system uses resistance measurements ahead of the drill bit to detect approaching coal in real time. This method of detecting “Top of Coal” brings significant benefits to surface mining operations, Mining3 says, including:

  • Providing a reliable indication of the approach to “Top of Coal” that will enable drilling to be stopped before touching coal or at a minimum standoff distance;
  • Increase production by reducing damage to coal from blasting; and
  • Strata recognition and mapping during routine blasthole drilling.

The system can also be retro fitted to a standard rotary air blast drill rig.

CR Digital, part of the global CR Group, is now working with Mining3 on the commercialisation of the technology, and the integration of the Top of Coal technology into its technology portfolio.

Together, CR Digital and Mining3 see potential for the technology to be an extension to the Thunderbird 1110 and StrataSense products within the CR Digital portfolio.

“Collectively, this agnostic range can be retrofitted to any rotary air blast drill rig and is intended to build on the StrataSense capability of CR Digital, to compile a three-dimensional understanding of the bench and coal seam in real time,” the companies said.
