MINEXPO PREVIEW
Caterpillar’ s revolutionary fully mechanised longwall Rock Straight System designed for continuous mining of flat and tabular deposits in hard rock
technology that meets US EPA Tier 4 Final and EU Stage IV certification requirements. Complementing the R1700K are new ground engaging tools for LHDs and a simulator demonstrating Command for underground, the Cat system for remote and semi-autonomous operation of LHDs.
In addition to displays of its surface and underground mining equipment, Caterpillar will dedicate areas to technology, data analytics, equipment life-cycle management and the global Cat dealer network.
“ At our core, we’ re committed to making quality products that are safe and reliable,” says Johnson.“ But we also recognise that the stepchange results our customers need don’ t rely solely on the machines. In the‘ age of smart iron’ it’ s technology, data and automation that will be the game-changer. And when we combine this with a focus on site performance, analytics and knowledge-partnering with our customers, we’ ll deliver the sustainable efficiencies our customers need today, and in the future.”
Sandvik will be revealing the DD422iE battery tramming jumbo, among other products designed to increase profitability and decrease operational costs. Optional 3D scanning is one of several innovative features available for this jumbo. It automatically scans overbreak and underbreak to save valuable time during the drilling cycle, helping operations develop more metres every month.
This simple automatic scanning process uses
lasers to guide the drill to its exact position, saving valuable setup time each drilling cycle. It measures angles and distances around the rig, comparing them with previous scans in its memory to locate a drilling location with perfect precision.“ Just press a button, either from the cabin or from a remote controller, and the automated rig navigation will start immediately.”
Performing a continuous overbreak and underbreak analysis, the scanning unit helps optimise the drilling and blasting cycle and produces an accurate profile. 3D scanning analyses blasts and continuously relays information. Using smart iteration cycles it analyses the geomechanical plane of the rock, increasing accuracy, reducing cycle times and ultimately enabling more drilling at less cost. It also analyses blasts and relays information back allowing the development of even better profiles for future use.
The scanning technology works with iSURE, Sandvik’ s integrated solution to combine tunnel line, theoretical profile design, drill plan design and data collection analysis.
By using electric energy from an onboard battery during tramming, the Sandvik DD422iE produces zero emissions while manoeuvring between headings. This improves health and safety for miners working underground and reduces ventilation costs.
“ The jumbo’ s intelligent power management system helps you meet ever-increasing productivity requirements despite often limited underground electric power capacities.”
Revolutionary Sandvik driveline technology enables the battery to recharge during the drilling cycle using the mine’ s existing electric infrastructure. The battery will even recharge as Sandvik DD422iE is tramming downhill by using energy generated by the braking system.
The company will also demonstrate its extensive experience in surface and underground drilling – whether top hammer, ITH, DTH or rotary. This includes the launch of the latest addition to the modular 400 underground range of ITH long hole drill rigs with automation capability. Visitors will also learn more about the latest in the series of diesel powered, self-propelled, crawler-mounted surface blasthole drills( automation-ready) featuring forward-thinking design and technology for bulk mining operations. Coupled with the patented Sandvik Compressor Management System fuel consumption can be improved by up to 25 %.
Sandvik continues to innovate in drill bit design. The newly-introduced top centre drill bits, incorporating the most significant upgrade to face drilling bits in decades, is one of the MINExpo highlights. The new design features a so-called“ raised front“, elevating two or three
Coupled with its smart battery charging system, the DD422iE jumbo will help maximise utilisation of a mine’ s electrical infrastructure
