Sandvik Mining launches next-generation blasthole drill

The Sandvik Mining DR461i is a diesel powered, self-propelled, crawler-mounted blasthole drill that is automation-ready and features forward-thinking design and technology for bulk mining operations.

It is designed to withstand the harshest conditions and equipped for rotary or down-the-hole (DTH) drilling. The DR461i was developed from the preceding DR460 drill rig and includes upgrades that make the drill extremely reliable, easy to maintain and safe.

“For decades, customers have counted on Sandvik to develop the most durable products on the markets – rigs that will be able to work a mine site for decades,” says Ken Stapylton, vice president of rotary drilling, Sandvik Mining. “In developing the DR461i, we’ve taken our customers’ feedback into our research and development efforts and are proud of the newest addition to our drilling equipment product line.”

Safety is a top priority at Sandvik Mining, and the DR461i includes several safety enhancements such as autonomous pipe handling, above-the-deck bit change, additional walkways, hand railings and safety interlocks. The drill was designed to fully comply with the various safety standards around the world, such as Mining Design Guidelines (MDG) for mobile and transportable equipment in mines, Earth Moving Equipment Safety Roundtable (EMESRT) Design Philosophies and CE conformity marking.

Additional highlighted features of the DR461i rig include:

Ergonomically-designed cab

The Sandvik DR461i has a completely new cab designed to ensure the maximum comfort and ease of operation for the operator. The cab includes air conditioning and sound insulation to 80 decibels or less. It also offers unique “all in the seat” drilling and tramming controls, as well as a roof designed as a canopy, which sits above the actual roof with a four-inch air gap between them. Due to the air gap beneath it, the actual cab roof will heat up less, keeping the cabin at more comfortable temperatures.

Graphical User Interface (GUI) System

The GUI system digitally displays the features of the DR461i while operating and tramming. Running off of the CanBus system on the drill, it acts like an electronic depth counter and drill monitoring system in one, picking up information that sensors monitor in different parts of the machine such as the motor, compressor, rotary head, tracks, etc. It then represents this data through an interactive touch screen that the operator can then easily scroll through in order to keep track of the condition of the drill, how it is drilling, whether it needs maintenance, etc.

Hydraulic main access stairway

Developed to be a safer alternative to accessing the drill rig rather than using vertical hanging steps, the stairway enables the operator or maintenance personnel to bring tools up onto the drill with a reduced risk of falling. It is designed to be self-leveling depending on the topography of the ground around the drill, and was also built to accommodate the different heights of the drill levels depending on the height of jack extension.
