‘It could be used, for example, to investigate potential blast patterns for a greenfield site, where numerous scenarios can be quickly generated and calculations checked.’ ‘The blast design calculator utilizes user inputs – including burden, spacing, stemming height, sub-drill, hole diameter, bench height and explosive type – to determine explosive loads, powder factors and other outputs. ‘The blast design calculator is a series of guiding formulas that allows a blaster or engineer to plan a blast from start to finish,’ said BME’s global manager of blasting science, D. Mr Liebenberg said that while the app is not a blast design tool, it is a powerful means of verifying blast design outputs and making important blast planning decisions. ‘This platform gives our Blasting Guide a mobility and ease of use that makes a blasting engineer’s job easier and more productive.’ ‘The new app is an integral part of BME’s pioneering approach to harnessing the power of digital technology in the blasting sector,’ said Christiaan Liebenberg, software product manager at BME. The app runs both metric and imperial unit measurements, making it useful across the globe. Other app features include surface blast design rules of thumb, environmental guidelines, a table of common rock properties and a BME contact directory by country. It includes a blast design calculator, quick calculators and prediction calculators.
