DRILLING BLASTING Self contained single boom jumbo ensures long drilling period SANDVIK MINING ROCK TECHNOLOGYS DT912D single boom jumbo serves as a self contained air mist flushing diesel hydraulic unit The jumbo features an electric controlled drilling system with added automatic functions including one hole automatics and an SB150 universal boom for large optimally shaped coverage and full automatic parallelism An onboard compressor and 265 gallon water tank allow the DT912D to operate independently from the tunnel or mine infrastructure to guarantee a longer drilling period The DT912D provides quick safe and balanced tramming because of its four wheel drive articulated carrier In addition the cabin is available with a cabin lifting system that allows more visibility to tramming and drilling The Sandvik Intelligent Control system Architecture with comprehensive built in diagnostics also ensures the jumbo is easy to use and maintain rocktechnology sandvik Drill rig fills gap between small large drill rig models ATLAS COPCOS DM30 II is a crawler mounted hydraulic tophead drive multi pass rotary drill rig that fills a gap between larger and smaller drill rigs Atlas Copco modeled the DM30 II after its DM45 and DML models The drill rig features a 30 ft drill pipe changer and a standard four rod carousel With a starter rod under the rotary head the DM30 II has a total depth capacity of 145 ft In addition the DM30 II comes with a Cummins Tier 4 Final engine and an Atlas Copco 1050 cfm high pressure compressor It is capable of both rotary and down the hole applications The drill rig offers a spacious electric over hydraulic cab increased decking access and improved rod handling www atlascopco us Blast design system detects productivity issues MAPTEKS BlastLogic blast design and management system enables mines to preempt risk and productivity issues before they emerge through instantaneous sharing and visualization of operational data According to the company BlastLogic accelerates the process of developing and implementing accurate blast designs and it provides measurements and reports on blast execution process These features are achieved through real time data integration reporting and 3 D visualization that can be viewed by users throughout the blast design and execution process In addition BlastLogic quickly relates fragmentation results to blast and geology parameters in order for users to optimize fragmentation to improve dig rates and crusher throughput The tool helps engineers enhance future designs and better informs operations of expected postblast ground conditions www maptek com 38 PIT QUARRY January 2018 pitandquarry com
