Driving Success through Innovation
DynoConsult employs advanced technologies to measure cost savings and productivity gains for its customers.
These include:
High speed digital filming and motion analysis photography High Speed filming provides valuable quantitative information about how rock structure, firing sequence, burden movement and explosives energy interact to affect fragmentation and muckpile formation. High-speed photography is also useful when a blast design is not providing the outcomes expected, or when faced with specific blast related problems requiring quantitative diagnosis. High-speed photography has been used to determine appropriate timing and burden relief for optimising overburden casting operations and so to help identify the causes of oversize material, coal-edge loss mechanisms, airblast and flyrock.
Digital Video Digital video is also routinely used to provide a record of blast sequence and behaviours in those situations where detailed quantitative analysis is not required.
Velocity of Detonation Monitors A number of different methods are used to measure velocity of detonation in a wide range of applications. Conventional point to point instruments are ideal for determining product performance. Continuous VOD measurement techniques provide detailed analysis of inhole explosive detonation characteristics. This technique has been used to assess detonation rate, booster performance, gap sensitivity, effect of water on the explosive column and product quality issues, both in the field and at Dyno Nobel’s test facilities.
Vibration and Air Blast Monitoring / Analysis DynoConsult uses a number of seismograph systems to monitor ground vibration and airblast. If there is concern about damaging structures or exceeding environmental limits, then analysis of monitored results enables the optimisation of blast design within vibration and air blast constraints.
Synthetic Waveform Analysis and Blast Design By monitoring a single "signature" seismic waveform, DynoConsult provides analysis and blast design recommendations to minimize and optimize environmental effects from blasting. By using state-of-the-art software, explosive products, and process control techniques, our team of specialists can help you achieve your seismic control goals.
Laser Profiling and Borehole Surveying DynoConsult can provide face profiling and borehole surveying to maximise the efficiency of explosive energy distribution and to minimise the risk of airblast and flyrock. Laser surveys in large open pits, pre-blast and post-blast, enable optimisation of excavation and an estimation of material quantities blasted and/or dug. This information can be integrated with mine based survey systems.
Photogrammetry Through the use of three dimensional (3D) digital photography and specialized software, DynoConsult can efficiently map and analyze rock mass structures, face profiles, wall damage and blast effects for final pit wall designs.
Fragmentation Analysis Photographic techniques allow the assessment of fragmentation distribution within a blast. This information can be used to establish a fragmentation model for existing blast practices. The effect of subsequent blast design changes on fragmentation can then be estimated using available blast simulation software.
Computer Based Simulation and Analysis DynoConsult has access to a wide range of sophisticated blast analysis and simulation tools. DynoConsult computer models have blast design, simulation and vibration analysis capabilities and can estimate fragmentation and damage. Sophisticated blast editing and design tools allow input of both surface and underground blasts. Complex blast designs can then be formulated quickly and both explosive energy distribution and firing sequence can be examined prior to charging blastholes. DynoConsult is also working with its alliance partners to develop complex blast models to predict blast movement, muckpile profile etc.
