Importance of VoD Testing – Is it just for specialists or should everyone be doing it?

In the demanding and precision-oriented field of mining, the Velocity of Detonation (VoD) stands out as a critical factor that can significantly influence the outcome of blasting operations yet VoD measurement is often neglected , leading to less than optimal blasting results.

The introduction of the ShotTrack VoD unit provides an easy-to-use solution that enables both specialists and non-specialists to accurately monitor VoD, thus enhancing blasting operations and achieving more predictable and controlled outcomes.

This post delves into the transformative impact of VoD in optimised blasting and the benefits of integrating regular VoD monitoring into mining operations.

 

The Crucial Role of VoD in Optimised Blasting

Velocity of Detonation (VoD) is a critical performance metric for explosive products, directly influencing energy release, pressure generation, propagation distance, and confinement effect. In mining, where explosive performance is paramount, understanding and optimising VoD can significantly impact the efficiency and safety of blasting operations. Despite its importance, VoD often gets overlooked and is not consistently tested in blasts.

Optimised Blasting through VoD Monitoring

VoD is an essential parameter in achieving optimised blasting outcomes. Regular quality control of explosive products through VoD measurements ensures consistent and effective blasting results, leading to improved safety, cost efficiency, and data-driven decision-making.

User-Friendly VoD Equipment: ShotTrack VoD Unit

The ShotTrack VoD unit is designed with ease of use in mind, allowing even non-specialists to perform VoD measurements effectively. By making the equipment accessible to a broader range of users, ShotTrack ensures that VoD monitoring can be integrated into regular blasting operations without requiring specialised expertise.

Comprehensive Guidance

To further ensure ease of use, comprehensive instructions and diagrams are included on the coaxial cable itself, guiding users through the setup and operation process.

Importance of Consistent VoD for Blast Design

Significant effort goes into designing the “perfect” blast, considering factors like hole depth, width, spacing, burden, geology, and desired fragmentation. However, all this meticulous planning can become redundant if the energy release/VoD of the explosive product do not match what the shot was designed for. Ensuring the VoD is consistent with the blast design is crucial for achieving the desired results. Even measuring a single hole in every blast will help to ensure a consistent blast performance.

Benefits of Regular VoD Monitoring

  1. Consistent Performance: Regular VoD checks help maintain consistent explosive performance, leading to predictable and controlled blasting results.
  2. Improved Safety: By detecting and addressing any deviations in explosive behaviour, potential safety hazards can be mitigated.
  3. Cost Efficiency: Optimised blasting reduces the need for secondary breakage, lowers operational costs, and improves overall mining efficiency.
  4. Data-Driven Decisions: Continuous VoD monitoring provides valuable data, enabling data-driven decisions to enhance blasting strategies and outcomes.

By integrating these features, the ShotTrack VoD unit supports optimised blasting operations through regular and reliable VoD monitoring, accessible to a broad range of users.
