Sandvik continues to grow its battery-electric equipment offering. The new fully automated Sandvik DL422iE top hammer longhole drill is equipped with an electric driveline system to eliminate diesel emissions while tramming. This increases productivity while reducing environmental impact and creating a healthier working environment underground.
The zero-emission Sandvik DL422iE joins Sandvik DD422iE as the company’s second battery-driven underground drill. Sandvik expects to offer a full range of battery-tramming rigs covering all underground drilling applications by the end of 2021.
The new Sandvik DL422iE is designed for underground mass mining in 4 x 4 m or larger production drifts. It features the latest intelligent technology to enable continuous and unmanned operation, with automation and teleremote for drilling during shift changes and breaks. These features, combined with comprehensive data collection and transfer through wireless networks, improve equipment utilisation and productivity.
Emission-free carrier and tramming
As the industry’s focus on sustainability increases, Sandvik’s latest drilling solutions specifically address the challenge of providing enhanced operational drilling performance combined with reduced emissions. Sandvik DL422iE is mounted on a C400E 4-wheel drive frame steered carrier equipped with an electric driveline system (battery package and electric motor) for zero diesel emissions and reduced operating costs. The batteries can be charged during drilling (a newly patented feature), while electric power can be drawn from the electrical supply system from the mine’s network.
Sandvik DL422iE helps mines reduce overall emissions and ventilation and fuel costs, and to create a healthier working environment. Thanks to shorter cycle times and increased drilling capacity, Sandvik DL422iE has the potential to help mines increase drilled meters per shift by up to 10%. Productivity can increase by up to 20% via improved equipment utilisation.
Extensive automation features
As standard, Sandvik DL422iE is equipped with Sandvik’s Platinum drilling automation package for continuous and automated production drilling. This is combined with the i-Class iSOLO drilling control system to maximise productivity and enhance accuracy in drilling fans and parallel longholes. It acts as a full-time stinger control and is used in uploading drill plans to the control system, with drill plan management direct at the user interface to ensure one-hole automation drilling to a predefined depth. Furthermore, feed and boom positioning to the next hole are automatic, while data is transferred via WLAN ethernet connection.
Sandvik DL422iE can be equipped with an optional automatic bit changer, enabling autonomous drilling of complete fans and working through shift changes. In addition to being equipped with MySandvik remote monitoring, units can also be integrated with AutoMine and OptiMine, providing multi-unit control and fan-to-fan remote tramming.
