MMSM – Orica successfully completes first ever Electronic Blasting System – TigerDet Training & Demonstration in Nepal – Upper Seti HPP
The application of advanced blasting technologies is essential for improving safety, precision, and excavation efficiency in large hydropower projects. On 12th December 2025, Electronic Blasting System (EBS) – TigerDet was successfully introduced at the Upper Seti Hydropower Project through a controlled blast conducted by Mohanman Shaktiman, authorized Channel Partner of Orica in collaboration with blasters and geologists of Upper Seti Hydropower Project. The blast employed Orica’s TigerDet electronic detonators with Orica – Blaster marking a significant advancement in blasting practices at the project site.
Mr. Kamal Nayak, senior mining engineer and export manager from Orica India along with MMSM Blast Tech-Geologist Mr. Lok Raj Bajgai conducted training on safe and efficient operations of the Electronic Blasting System TigerDet to the site blasters, geologists and project manager of Upper Seti Hydropower Project.
The training was conducted both on open and inside the tunnel. The site blasters and geologists are now fully capable of handling TigerDet and Blaster by themselves to conduct future blasts. Nepal Army personal in-charge of security at site have also been briefed about this new technology in blasting and were also present during the training. The blast resulted in uniform fragmentation, reduced overbreak, and improved excavation profile control.
Electronic blasting systems use digitally programmable delays and allow verification of circuit integrity prior to firing, significantly improving safety and precision. TigerDet in case of projects in Nepal would be primarily used just to initiate the blast in absence of electric detonators. Electric detonators were earlier and still being used to initiate blasts. However, following a ban of electric detonators by Government of India due to the safety concerns of electric detonators, electronic detonators are being widely used in India and now in Nepal. 
The successful implementation of electronic blasting represents a significant step toward modernizing blasting practices in Nepal’s hydropower sector.
Orica’s TigerDet electronic detonators offer millisecond-level delay accuracy, programmable timing, and resistance to electromagnetic interference. The electronic blast conducted on 12th December 2025 using Orica’s Tiger Det system under controlled conditions with full digital testing and validation before firing marks a milestone for the Upper Seti Hydropower Project and sets a benchmark for future projects.
