Delivering high-quality bulk emulsion explosive to a remote island in the Atlantic Ocean – and ensuing problem-free blasting for a two-year project – has proved BME’s ability to design and manufacture a safe and reliable product suited to the most demanding conditions.
Daunia Open Cut coal mine in the north-eastern state of Queensland, Australia, has broken the world record for the largest electronic detonator blast ever – firing 5,665 detonators in 2,683 blastholes using the AXXIS™ digital detonation system from BME.
It is well known that good blast design ensures an effective distribution of powder that improves blast results and reduces drilling and blasting costs. Now, through the use of unmanned aerial vehicles (UAVs or drones), global positioning systems (GPS) and three-dimensional (3D) photogrammetric software, the field of blast design has been taken another step forward.
Bulk emulsion explosives have come a long way since BME introduced double-salt – ammonium nitrate and calcium nitrate (AN/CN) – cold emulsion products into South Africa over 30 years ago.
In another record blast for BME’s AXXIS digital initiation system, Omnia Subsidiary Advanced Initiating Systems (AIS) successfully blasted 4,485 detonators in a coal mine in Australia’s north-eastern state of Queensland.
Umesh Chhika, general manager for Asia Pacific and strategic projects at BME, said the company has been engaged to provide electronic detonation systems and related technical advice to ensure low-vibration blasting in the 35 metre-deep box cut, from which three more rail tunnels will be developed.
