Global debut for Sandvik’s Leopard DI650

Surface Drilling & Exploration and Sandvik Mining and Construction. Pipe sizes range from 89 to 140 mm, depending on the size of the hammer. Maximum hole depth is 53,6 m when using the carousel option with pipe sizes from 89 to 114 mm. The capacity range of the 403 kW Tier 3 CAT C15 diesel engine and the compressor is adequate for high-pressure drilling with 4-6.5 inch DTH hammer sizes. With good visibility to the drilling area and a single integrated touch screen for all monitoring, diagnostics and mining automa- tion displays, the Leopard DI650i’s ergonom- ic iCAB cabin provides the rig operator with a safe, productive working environment. With both safety and uptime in mind, the maintenance crew can carry out all daily servicing tasks at ground level on both sides of the machine. “The advanced serviceability and reliability features can increase the Leopard DI650i’s availability by up to 20% compared with conventional DTH rigs at a similar technology level,” explains Lahdelma. Intelligent control technology applied in both the compressor and the hydrau- lic system’s cooler fan can reduce fuel consumption by up to 15% compared with conventional DTH rigs. The Leopard DI650i’s fuel efficiency is further boosted by the flow-controlled drilling control system that eliminates fluctuations in airflow, instead allowing the pressure level to fluctuate in response to more difficult ground conditions and increased back pressure (for example, due to groundwater or collapsing holes). b

The Sandvik Leopard DI650i DTH drill rig is designed for high-capacity production drilling applications in surface mining.

Sandvik Mining and Rock Technology used Electra Mining Africa 2018 to introduce its new, intelligent down-the-hole (DTH) surface drill, the Sandvik Leopard DI650i. Combining proven engineering solutions and innovative new components, the new DTH drill rig is said to offer better fuel efficiency, improved safety and higher productivity in challenging rock conditions. “The Sandvik Leopard DI650i DTH drill rig is designed for high-capacity production drilling applications in surface mining and large-scale quarrying applications,” explains however, achieving a digital mining trans- formation is often seen as a looming burden upon mining companies due to additional installed connected devices. “This is because cost and maintenance is perceived as much harder than current main- tenance practices. This is not the case at all, and simplified strip-and-replace as well as plug-and-play technologies are being incorporated within the connected devices layer of IoT platforms,” says Ramsay. Connected and agile mining operations are critical to organisational change and process re-engineering. The value extracted is generated through technology enablement and integration of the data and systems. They are a combination of four key elements: 1. Smart mining – this is the process of collecting data across equipment, people, and within the mine to create the ability to utilise insight through

Joanne Cooke, President of Surface Drilling and Exploration at Sandvik Mining and Rock Technology. It comes with a range of new or re- designed components to boost productivity. The standard rotary head option, the HTRH6, has a proven track record on current Sandvik DTH rigs. “For the Leopard DI650i, we also offer a new heavy-duty option, the MRH6, which is designed to perform in tough environments and for drilling larger hole sizes. It is a perfect fit for Sandvik’s new RH560-series DTH hammers,” explains Ilkka Lahdelma, director, Product Management, automated or human response. Data is used across all areas of the mine to enable users to understand what is happening; anticipate future events and embed those insights and feedback within processes that enable the business to respond. 2. Digital mining – this is the use of data to build a digital working model of physical products and processes. It is used for understanding, scenario modelling and simulation to test scenarios for extreme efficiency or any other optimised outcome, for example, safety. The control centre is the core of successful mining operation and application of advanced analytics and collaboration are centralised here. 3. Automation – this includes automation of equipment via robotics, for example,

predictability. 4. Integration – this is the ability to

integrate the operation as a system, from resource to final user and from supplier to customer. A holistic strategy brings together the collection of data and hence responsive operations are created. The responsive operations help automate and create digital processes. b
