ELTEK Hellenic Explosives Technology has successfully executed the largest underground up-hole blast ever performed in Greece, marking a significant milestone in underground blasting operations.
For this landmark blast, ELTEK developed a specially formulated up-hole emulsion matrix, capable of achieving a flexible density range from 0.80 to 1.25 g/cc, enabled by an advanced chemical sensitization process. Priming and charging operations were carried out by ELTEK’s experienced crew using ELTEK Dynamis Boosters in combination with Digishot+ 4G electronic detonators, ensuring high accuracy and reliability.
In-borehole VOD measurements exceeded 5,500 m/s, confirming optimal detonation performance and resulting in an excellent and fully successful blast outcome.
The operation utilized a purpose-designed up-hole charging unit, engineered by ELTEK to allow precise and controlled up-hole charging, even under demanding underground conditions.
In total, the blast involved the installation of 428 electronic detonators and approximately 12 tonnes of emulsion explosives. The blast was remotely initiated from the surface, leveraging state-of-the-art electronic initiation technology to maximize safety and operational control.
