In late 2008, Global Survey was awarded NZ’s largest machine control contract to supply Leica fleet management and machine guidance solutions to Solid Energy at their Stockton coal mine north of Westport. The project involves installation of Leica’s Jigsaw 360 systems on 30 items of plant, plus installation of a wireless broadband network to cover the mine – an area of 8 x 3km. Systems installed include drill-rigs, excavators, dozers, wheel loaders, haul trucks and supervisor vehicles. Our teams have spent the last 3-4 months completing the installation of the hardware and are currently involved in commissioning and customer training.
For Solid Energy, the system will allow them to automatically schedule and optimise movements of haul trucks and excavators, improve safety when working above old underground workings and track coal movements from the pits to the stockpiles. Comprehensive reports are available in real time or at shift change to enable analysis of performance against customised KPIs. Visibility to the system is controlled by Solid Energy’s IT department, ensuring those who need to know get access to the data they need, right when they need it.
In order to map old underground workings, Solid Energy and Chris Coll Surveying have been Laser Scanning (including the Leica Scanstation and the MDL cavity scanner) to create detailed and accurate maps which are used to generate hazard zones for the Leica fleet management system.
The system is scheduled to ‘Go Live’ on June 1st, when the many stakeholders at the mine will be analysing the results for improvements in safety, operational costs and product quality.
