Sandvik has released the DL422iE battery-electric top hammer longhole drill, which produces zero emissions and is fully automated.

The drill features an electric driveline system that eliminates diesel emissions while tramming, as well as automation and teleremote for drilling during shift changes and breaks.

This owes to Sandvik’s Platinum drilling automation package which provides continuous and automated production drilling.

Combined with the i-Class iSOLO drilling control system, Sandvik stated that productivity was maximised and accuracy enhanced when drilling fans and parallel longholes.

The unit can increase drilled metres per shift by up to 10 per cent, and productivity by up to 20 per cent via improved equipment utilisation.

Its batteries can be charged during drilling, while electric power can be drawn from the supply system in the mine’s network.

The Sandvik DL422iE, which is mounted on a C400E four-wheel drive frame steered carrier, also provides direct access to drill plan management at the user interface.

This helps to ensure one-hole automation drilling to a pre-set depth.

The equipment is also capable of drilling vertical and inclined fans and single or parallel Ø89-127 millimetre longholes up to 54 metres in depth.

Its drilling capacity, reliability and operating cost are optimised by the 33 kilowatt HF1560ST longhole rock drill.

Mining companies can choose to equip the machine with an automatic bit changer to enable autonomous drilling of complete fans.

It is also equipped with MySandvik remote monitoring and can be integrated with AutoMine and OptiMine, providing multi-unit control and fan-to-fan remote tramming.

The Sandvik DL422iE is the company’s second battery-driven underground drill, suitable for underground mass mining in four by four metres or larger production drifts.

Sandvik plans to release a full range of battery-tramming rigs covering all underground drilling applications by the end of the year.
