Renishaw's new Quarryman Pro uses innovative technology to help optimise blasting
“This module and the calculation methodology behind it provide pertinent information on the energy efficiency of the drilling and blasting operation. Comparisons can now be made between different patterns and/or designs, and try to optimise their environmental and energetic impacts.
The software deals with the environmental impact of the drilling and blasting operation and it is important to note that in any study of the environmental impact of a quarry operation this must be combined with data that also takes into account the footprint of the other parts of the process such as load haul, crushing and secondary processing.
“This ‘holistic’ approach allows a proper balance to be struck between the relative environmental impacts of all parts of the communition process.”
The next step
“As outlined, the technology now exists to be able to accurately measure the confinement on each part of each hole in a blast and to load variable energy explosives in the hole to suit that confinement. In addition the carbon footprint of each blast can be reasonably estimated,” say Chavez and Farnfield.
“Clearly a highly competent rock will require more energy to blast than a weak or broken rock and the reliable collection of such data is the missing link in our blast design process.
“Drilling equipment is now becoming available that can be equipped with the so-called ‘measure-while-drilling’ technology thus giving a record of various rock parameters for each hole in a blast. We can therefore look forward to the day in the near future that it will be possible to automatically adjust the explosive energy to not only match the confinement of the hole but also the competence of the rock.”
Quarryman Pro Renishaw
’s says its new, speed-optimised rockface profiling and laser scanner system, the Quarryman Pro, uses innovative technology to help optimise blasting, “contributing to the profitability of quarrying operations.”
The system, which also helps to improve safety, is said to have been an essential on-site system for quarries for over 20 years.
The original Quarryman, and later models, “transformed safety on site and enabled forward-thinking quarry managers to simply and swiftly modify processes, to decrease post-blast workflow and costs.”
Martin Carr, business manager, mining systems, says: “Customers using the new Quarryman Pro alongside Renishaw’s Boretrak system to optimise blasting will see a significant competitive advantage: quite simply, they will access accurate data more quickly, in a wider range of conditions, and be more easily able to export data to other mining software packages.
The new Renishaw Quarryman Pro is said to be optimised for speed of operation in tough environments, with swift setup, programming, scanning and data processing, and offers significant benefits over previous models, says the company.
