Orica Turns Wireless Blasting Dream Into A Reality At Europe’s Deepest Mine



In Europe’s first demonstration of wireless blasting, Orica has enabled First Quantum Minerals’ (FQM) Pyhäsalmi underground mine in Finland to recover ore it previously thought inaccessible.

Orica’s WebGen™ 100, the first truly wireless rock blasting system, has been used in trials at the zinc-copper-pyrite mine since September 2018, with FQM, to date, carrying out five blasts.

Since the invention of the safety fuse by William Bickford in 1831, there has been three revolutions in blast initiation methods – electric detonators (1930s), shock tube (1980s) and electronics (~2000s). Every new initiation method development has increased the safety, precision and possibilities of initiating blasts.

The new Safety Integrity Level 3 certified WebGen system could end up being the fourth revolution in this line-up, Orica believes.
