Improving safety and productivity with the world’s first wireless electronic blasting system
27 Sep 2017
Melbourne, Australia: Orica (ASX: ORI), the world’s largest manufacturer of commercial explosives and innovative blasting systems, today announced the successful production trials of the premium WebGen™ 100 wireless electronic blasting system.
WebGen™ 100, signals a step-change in in-hole initiation and decisive step on the path towards full automation of drill and blast operations in the future.
The system provides for groups of in-hole primers to be wirelessly initiated by a firing command that communicates through rock, water and air. This removes constraints often imposed by the requirement of a physical connection to each primer in a blast.
Orica Chief Commercial Officer, Angus Melbourne described the technology as being a game-changer for the industry, saying, “WebGen™ is a world first technology and that is something we are very proud of.
“The WebGen™ 100 wireless blasting system not only improves safety by removing people from harm’s way, it improves productivity by removing the constraints imposed by wired connections and importantly is a critical pre-cursor to automating the charging process.
“The entire industry is moving rapidly towards an automated future and the introduction of WebGen™ signifies that we, Orica, are serious about being a big part of this automated future.”
Successful wireless implementation in Australia and Canada
Two production trials have been executed recently to validate and prove the benefits of the technology. The first production blast took place at the Glencore operated Ernest Henry Mine (EHM), a large Sub Level Cave (SLC) operation in North West Queensland, Australia.
During the trial, 30 rings were pre-charged with WebGen™ well in advance of the cave and then initiated from Mine Control on the surface. WebGen™ eliminated the need for mine site personnel to work near the brow to hook up the blasts, and also demonstrated that lost brows would not remain a production risk. The system was easily integrated into their current method of operation with no misfires or production delays.
In a second production blasting trial at Goldcorp’s Musselwhite Mine in Northern Ontario, Canada, five temporary rib pillars were pre-charged using Orica’s WebGen™ primers.
The main body of the ore panel was blasted and extracted first while the temporary rib pillars held back the waste rock backfill. The inaccessible ore pillars were then blasted. The introduction of this technology delivered reduced dilution, increased truck fill factors and improved overall productivity.
Orica’s first explosive product to obtain a Safety Integrity Level (SIL) 3 rating
During July, the WebGen™ system obtained Safety Integrity Level 3 (SIL3) certification, through TÜV Rheinland, a global leader in independent inspection, safety testing and certification services. A SIL 3 component running continuously is classified as having a safety critical failure less than 1 in a 100 billion devices, this is the highest level that can be practically achieved for a commercial blasting product.
Orica is now working to produce a wireless primer specifically for surface mining applications that will deliver greater flexibility to the open cut mining sector in coming years. This is a critical first step towards full automation of the drill and blast process across the underground and surface mining sectors, a long-term goal shared by both the mining industry and Orica.
WebGen™ will be featured at the AusIMM Underground Operators Conference held on the Gold Coast, Australia in October. For more information and presentations on the WebGen™ system, please visit Orica at trade stand 42 & 43.
