The best in new technology

◢ Drill durability

 JoyGlobal_hydraulic_drill  Designed for use at hard rock operations in harsh conditions, Joy Global’s new rotary blasthole drill seeks to minimize maintenance downtime. The P&H 285XPC diesel hydraulic drill can operate in -40 C temperatures and is designed for 270- and 311-millimetre diameter hole applications, making it ideal for iron ore and copper operations. “We were looking to provide a drill best suited for that market that combines the reliability and productivity of other drills we have in our product line,” said Eric Wilkinson, product manager for drills. The diesel power unit in the 285XPC facilitates mobility for various drilling functions around mine sites by removing the trail cables necessary with an electric drill. The drill comes with Joy Global’s Universal Drill Cab to simplify training for operators familiar with other P&H drill models and also improve safety with unobstructed views of the drilling area through expansive windows. 

◢ Packing power

In March, Boart Longyear unveiled its LM110 underground diamond coring drill, which sports a new 110-kilowatt (kW) power pack. This allows users to drill efficiently at deeper depths with one-third more torque than the 90-kW power pack in the previous model. “That just means when you’re in a deeper hole, it’s much easier [to continue drilling],” said Justin Warren, senior global project manager. Due to the modular nature of the LM drill series, Boart Longyear is selling a 110-kW power pack kit separately, as it is compatible with its older models. This allows customers to upgrade their current drills by replacing the older power packs. Drillers also have the option of adding a rod handler to the new drill rig, making the rod-loading process easier and safer. They can also add Boart Longyear’s Drill Control Interface, which includes display and optimization functions like data logging, reporting and other productivity tools.

◢ Predict your blast fragmentation

 WipWare_blast_software Inconsistent and unexpected blasting results due to the unknown characteristics and variables in rock have the potential to cost companies millions of dollars in cleanup and additional fuel consumption. To improve blasting results, WipWare has added BlastCast to its suite of blast of fragmentation analysis software. The new tool allows customers to forecast blast fragmentation before actual blasting occurs. Users adjust their blasting parameters such as hole diameter and rock density, and BlastCast generates a graph that predicts blast fragmentation. After blasting, users compare the actual results with predicted results using photo-analytic technology and as they continue to blast and update parameters, BlastCast predictions become more accurate, unearthing previously unknown variables. “By solving that unknown, you’ve got a very accurate predictive model for the rock type under your operation,” said Tom Palangio, company president. “You keep using our software to measure but now you’re able to predict with more accuracy and finetune the blast to meet your specific needs.”
