E*BLAST Consulting offers a full-scale blast optimization for every blast application. Let us show you our magic!
23. 9. 2021 we have introduced the E*BLAST Consulting to our customers at International Blasting conference in Valec in Czech Republic.
Back in 2016, We were able to save 40 Workdays for the Largest Infrastructure Project in Norway
What we are proud of
Quarry Fragmentation improves by 15% while secondary breakage is reduced by 67%
Geology variation throughout the quarry made it difficult to keep consistent fragmentation. Most of the time the muckpile contained boulders that required intense secondary breaking by a hydraulic hammer. Subsequently, the blasts were creating uneven faces that were influencing safety on bench; making it harder for blast planning to keep the patterns uniform as needed for the desired final fragmentation.
Reduction of Ground Vibrations by 14% with Blast Size increase by 300%
Nonelectric blasts were generating unpredictable vibrations with a big value spread. When blasting operations get closer, vibrations get higher, and the spread gets bigger. Typical blast parameters are: hole lengths from 15 to 20 m, hole diameters 92 mm, burden 3.3 m and spacing 2.9 m. Charge weight might be a maximum of 27 kg per deck. The request was for the lowest vibration inside the caves – close to stalagmite.
Mill throughput improved by 46 % with reduction of critical size particles by 11 %
After several trials with different powder factors, the Phu Kham Mine decided to use our services and tailor the timing of their blasts using E*STAR detonators to bring the intended results.
