Application of DaveyTronic® with Synchroblast in controlled blasting
Blasting near critical structures
In inland Rio Grande do Sul, Brazil, a paint company had the goal to expand its production area in a location where it would have to excavate a rocky area of 4,000 m² using explosives. In this scenario, Boqueirão Desmonte sought a partner to carry out a large-scale blasting project at a critical distance from the existing factory structure. The factory housed tanks containing 80,000 liters of solvent, located approximately 10 meters away, in addition to offices and other nearby facilities.
“The timing between holes and lines was achieved using evolutionary switching strategies, and this, alongside Enaex, aided in the flawless execution of programmed times, utilizing the DaveyTronic® electronic detonators. The product’s precision and accuracy are very high and this greatly assisted in flyrock control, making a significant difference in energy optimization.”

Guaranteeing precise blasting control
Enaex proposed a solution to employ DaveyTronic® electronic detonators along with the O-Pitsurface software by O-Pitblast. This approach allowed for the automatic programming of timing, ensuring precise vibration control, eliminating operational errors, and ensuring optimal blasting performance.
Furthermore, the Synchroblast mode was employed to enable the simultaneous initiation of 2,900 DaveyTronic® detonators in a single event. This mode allows for the execution of large-scale blasting by synchronizing up to 3 Blast Drivers in a single firing, resulting in fewer blasting cycles and production interruptions. This ensures the operational continuity of the end customer.
The EMTS (Enaex Mining Technical Solutions) team played an extremely important role in the success of this project, thanks to their great expertise in specialized blasting and the use of electronic detonators. They were responsible for handling the software, planning the connections, applying the electronic detonators, managing circuits and electrical currents, as well as overseeing the firing procedure.
Excellence in execution
The blasting operation was completed successfully, setting a record for the highest number of electronic detonators initiated in an urban area by Enaex. The vibrations remained within the established parameters, resulting in no damage to the structures or adjacent tanks. Furthermore, there was no interruption to production, and evacuation occurred only during the blasting procedure, allowing for a swift area clearance, while immediately resuming production at the factory. This outcome was only possible due to excellence in the implementation of the electronic detonation system and the extreme precision that the DaveyTronic® detonators provided for the blasting results.
Enaex stood out as a strategic partner for the client, showcasing a strong and effective collaboration in project development. Through the implementation of efficient solutions, such as the use of DaveyTronic® electronic detonators and the O-Pitsurface software, the EMTS team played a pivotal role in overcoming the challenges faced.
