Technical Note: Nonelectric Detonator Initiation Mode of Operation A nonelectric detonator operates using a shock tube to transmit energy without the use of electrical signals, providing a safer and more reliable initiation system in blasting operations (Cardu et al., 2024). In this article, I provide a breakdown of its mode of operation: Stage 1: Shockwave Transmission through the Shock Tube The process begins with a high-energy shockwave traveling through the shock tube. This shockwave is generated when the blasting cap is triggered and moves at supersonic speed within the shock tube. Stage 2: Initiation of the Pyrotechnic Element Upon reaching the detonator, the shockwave ignites a pyrotechnic element housed within the detonator. This element is designed to convert the energy of the shockwave into sufficient heat and pressure to initiate the next stage of the process. Stage 3: Detonation of the Primary Charge The energy from the pyrotechnic element triggers the primary explosive charge inside the detonator. The detonation of the primary charge produces a high-energy shockwave. Stage 4: Initiation of the Booster and Complete Hole Charge This shockwave, in turn, initiates the booster explosive/Primer charge, which amplifies the energy and ensures the initiation of the entire explosive column within the borehole. The sequence ensures controlled detonation, optimizing fragmentation and minimizing hazards. Continuous Improvement Using WipFrag If a mine plans to switch from Detonator A to Detonator B, continuous assessment of blast performance is crucial to ensure the change improves efficiency and fragmentation quality. Here's how WipFrag software can assist: Baseline Fragmentation Assessment Use WipFrag to analyze fragmentation results from Detonator A. Capture and process images from muck piles to establish a particle size distribution (PSD) curve. This serves as the baseline for comparison. Comparative Analysis with Detonator B Conduct blasts using Detonator B and analyze the resulting fragmentation with WipFrag. Generate PSD curves and overlay them with the baseline to identify differences in fragmentation size and uniformity. Adjust Parameters for Optimization If fragmentation with Detonator B does not meet or exceed the baseline, evaluate and adjust other blasting parameters, such as charge weight or timing. Use WipFrag to assess the impact of these adjustments. Generate Specification Envelopes Create a specification envelope using WipFrag to set acceptable fragmentation targets, ensuring each blast meets operational requirements consistently. By integrating WipFrag into the evaluation process, mines can make data-driven decisions to optimize performance and reduce costs during transitions between detonator types. This approach ensures enhanced fragmentation, better crusher compatibility, and overall operational efficiency. WipWare Inc.

Stemming Length Effects on Fragmentation In blasting operations, stemming plays a crucial role in controlling the energy distribution within the blast hole. The stemming length directly affects fragmentation efficiency, with improper lengths often leading to poor fragmentation, fly rock, or excessive vibrations. Impact of Stemming Length on Fragmentation A short stemming length can result in premature venting of gases, reducing the energy available for rock breakage and increasing the risk of boulder formation. Conversely, an excessively long stemming may over-constrain the explosive energy, causing inefficient fragmentation. Both cases negatively impact downstream operations, increasing costs and delays in material handling and crushing. How WipFrag Can Help WipFrag, an advanced image analysis software, is a powerful tool for assessing the effects of stemming length on fragmentation. It enables users to: 1. Evaluate Boulder Formation: By capturing high-resolution images of the muck pile post-blast, WipFrag identifies and analyzes oversized particles that indicate stemming issues. 2. Analyze Particle Size Distribution (PSD): The software generates detailed PSD curves, allowing engineers to quantify the size range of fragments and determine how stemming adjustments affect fragmentation quality. 3. Optimize Stemming Practices: WipFrag’s merging feature facilitates the comparison of PSD results across multiple blasts. This allows for data-driven decision-making on stemming length optimization. 4. Boulder Counting and Specification Envelopes: Using tools like Edit Assist and specification envelopes, WipFrag helps isolate and measure large particles, providing insights into the stemming’s contribution to poor fragmentation. Continuous Improvement with WipFrag Integrating WipFrag into blasting operations ensures continuous assessment and improvement of blast designs. By correlating stemming length variations with PSD results, operators can fine-tune their practices to minimize boulders, enhance fragmentation, and reduce overall costs. #blasting #mining
