en.Wedoany.com Reported - The Russian EVOBLAST Group (Группа «ЭВОБЛАСТ») presented a comprehensive approach at a recent meeting, aimed at addressing issues in drilling and blasting operations (БВР) such as low initiation accuracy, insufficient control at various stages, and poor fragmentation quality through digitalization and electronic initiation systems. These shortcomings in traditional operations directly impact mining economics, especially under complex mine geological conditions.
One of the core elements of this comprehensive approach is the use of iDet® electronic detonators, which expands the variety of blasting network installation schemes, thereby enabling flexible control over seismic effects and fragmentation quality. The company's digital ecosystem "БВР Контроль" (Drilling and Blasting Control) is considered a key component of this approach. This platform enables end-to-end control from project loading to report generation, automatically analyzing drilling and blasting parameters, recording deviations, and reducing human errors. The system operates even under unstable network conditions: engineers load the project via the internet before going to the site, operators record drilling parameters offline, and data automatically synchronizes with the server upon returning to network coverage, allowing real-time analysis of deviations between actual and design parameters.
To address the issue of seismic effects from blasting in the pit wall area damaging rock mass and causing slope spalling and collapse, the EVOBLAST Group recommends detailed monitoring using in-hole and surface geophones, along with adjusting drilling and blasting parameters for the wall blocks. By using electronic initiation systems, decoupling intervals, and optimizing blasting direction, the level of seismic effects can be reduced by 1.5 to 2 times compared to traditional methods. Ivan Kovalchuk (Иван Ковальчук) noted that this approach improves wall stability and operational safety, while combining decoupling intervals with electronic initiation systems can increase the width of the wall block area excavated in a single large-scale blast by more than two times, improve excavation efficiency by 10% to 15%, and reduce the number of blasting days.
The EVOBLAST Group, together with Piklema, also demonstrated the EvoVision.Shovel hardware and software complex based on computer vision. Installed on an excavator, this system continuously analyzes the granulometric composition of the rock mass throughout the excavation cycle of the entire blasted block. It is compatible with most excavator models, operates under harsh climatic conditions, and requires no complex maintenance. The main tasks addressed by this system include: blasting fragmentation control, floor level control, loading cycle control, high-precision bucket positioning, optimization of drilling and blasting parameters, and improving the quality of mineral recovery. According to reports, EvoVision.Shovel can optimize drilling and blasting parameters, reducing specific explosive consumption by up to 25%, increasing excavation efficiency by up to 8%, and reducing drilling and charging costs by an average of 5%.
The developments showcased by the EVOBLAST Group cover aspects such as precise initiation in drilling and blasting operations, seismic monitoring, blasting fragmentation control, and the quality of mineral recovery. Operating in the Russian market since 1993, the company employs over 700 experts and undertakes projects ranging from the Kola Peninsula to the Far East, focusing on providing commercial explosives, engineering services, and innovative comprehensive solutions for the mining and construction industries.
