BME releases new blasting app

Global Mining Review,


BME has launched a new, free Blasting Guide application for Android mobile devices, enabling users to rapidly calculate and check blast designs.

Currently available for download from the Google Play Store, the new BME Blasting Guide mobile app replaces traditional paper booklets carried and referenced by in-field users. It includes a blast design calculator, quick calculators and prediction calculators. Other app features include surface blast design rules of thumb, environmental guidelines, a table of common rock properties and a company contact directory per country.

The app runs both metric and imperial unit measurements, making it useful across the globe. “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. “This platform gives our Blasting Guide a mobility and ease of use that makes a blasting engineer’s job easier and more productive.”

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.

“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 Global Manager Blasting Science, D. Scott Scovira. “The blast design calculator utilises 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. 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.”

Scovira added that the rules of thumb table – which summarises surface blast design guidelines – can be referenced by users as they access the blast design calculators.

The quick calculator includes a BME in-house formula for the target powder factor, as well as calculations related to the volume of rock to be blasted – either volume per hole or volume per blast. There are energy equations to compare different types of explosives based on their relative bulk strength, while hole-charging equations determine the mass of explosives going into a hole and address loading with gassed emulsion products. This helps determine column lengths and stemming lengths – with gassed and ungassed explosives.

The app’s prediction calculators include estimation of peak particle velocity and maximum charge weight per delay based on industry standard scaled distance equations and user defined ground transmission constants.

One of the prediction calculators can provide the user with guidance in estimating the blast clearance radius. The estimated blast clearance is based on maximum projected rock throw, calculated from scaled depth of burial equations and parameters. The scaled depth of burial equations and parameters are propriety to world recognised blasting consultant R. Frank Chiappetta of Blasting Analysis International Inc. and used by BME with permission.

“In line with its strategic commitment to collaboration in the digital space, BME engaged VIGA Interactive to create a world-class user experience and design, as well as Sympl Technology Solutions for the development work,” added Liebenberg.
