SAFER BLASTING

摘要

The Swedish company Transtronic AB has developed Devibench, a Windows-based system for electronic hole deviation measurement during bench drilling in quarries. The system, which comprises a bench probe and a robust PC, is easy to use and enables exact measurements in order to increase safety and optimise the blasting effect. According to the manufacturer, this provides reduced drilling costs, more even surfaces at the bottom of the holes and reduced vibrations.The first row of holes can be measured with great precision, enabling controlled blasting, which reduces the risk of human injury and property damage.
