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, increasing productivity while reducing environmental impact and fostering a healthier work environment. 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. Through these and other features, combined with comprehensive data collection and transfer through wireless networks, Sandvik DL422iE helps to ensure improved equipment utilization and productivity.
Sandvik DL422iE is capable of drilling vertical and inclined fans and single or parallel Ø89-127 mm longholes up to 54 m in depth using ST58 and ST68 tube rods. It is equipped with the powerful 33 kW HF1560ST longhole rock drill, which is based on a proven concept in terms of drilling capacity, reliability and operating cost. With an impact frequency of 40-45 Hz and optimized percussion dynamics for ST68 tubes, Sandvik DL422iE delivers optimal bit-to-rock contact for improved energy transfer. This leads to decreased stress level in rock tools, lower coupling/front housing temperatures and extended service life for shank adaptor and tube.
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 maximize 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.
In addition to the standard Platinum package, 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.
