Blast Preperation Audit

The foundation of the audit schedule is based on controlling and managing the resulting effects from blasting operations i.e. ground vibration, air blast, fly rock, fumes, fragmentation, explosive energy misuse, explosive quality deficiencies, improper blast controls, explosive stock control, improper blast results, safe and effective blasting procedures etc.

    High Speed Video

    Applications of high-speed video imaging include:

    • Immediate availability of the blast for review
    • Confirmation of the firing sequence of holes
    • Measurement of the firing time and scatter in detonators
    • Assessment of the degree of confinement
    • stemming blowouts and fly rock zones
    Fragmentation Analysis

    Application of Fragmentation Analysis:

    • Accurate measurement of fragmentation from existing blasting practices
    • Using actual measurements for future prediction of fragmentation
    • Uses digital photographic analysis for better quality and accuracy
    • Assist in blast design for optimum blasting pa
    Velocity of Detonation, Product Timing

    Application of Velocity of Detonation Measurements of explosive products includes:

    • Test the performance of explosives against the quality control standards set by the manufacturers
    • Measure the continuous VOD in any charge diameter under confined or unconfined conditions
    Face Profiling

    Performing accurate bench and blast designs with the following advantages:

    • Bench design according to free face
    • Accurate and correct first row Blast hole depths
    • Minimize fly rock from the face
    • Proper explosive energy application
    • Proper charging configuration calculations
    Borehole Inspections

    Application of Borehole Inspections:

    • Boretrak and Blast hole Inspector
    • Conducting blast hole inspection for quality of drilling
    • Determination of the hole quality concerning cracks, geological faults, fissures, faults etc.
    • Suspect holes can be inspected
    • Inspection of craters, tunnels through bore
    Blast Influence

    Influence of blasting operations on the surrounding environment is investigated. Investigate the related levels and possible influences of expected ground vibration, air blast, fly rock and noxious fumes on the area of 3500m surrounding the blast areas. The possible environmental or social impacts expected can be summarized in the following
