    Application of Numerical Modelling to Examine Damage in Wall Control Operations

    By P. Katsabanis

    Numerical modelling was used to examine damage in wall control operations. Decoupled charges appear to create larger damage zones than fully coupled low density charges with similar charge distributio

    South African Blasting Practice in Shaft Sinking

    By Rodney C. Espley-Jones, John C. B Wilson

    South Africa is well known for its shaft sinking exploits, and many of the world's biggest and deepest shafts are to be found there. Blasting practice differs in a number of respects from that followe

    The Laboratory Determination of Dynamic Pressure Resistance of Cap-Sensitive Explosives

    By Michael Wieland

    Sharp transient stress waves generated during the delay blasting of underground coal can damage unfired borehole charges remaining in the delay pattern. These tremendous stress pulses in coal bear a s

    Correlation Between Ground Vibration and Performances of Explosive (Ground Vibration by Underwater Explosion)

    By Minoru Kawamura, Koichi Kurokawa, Yukio Kato, Kenji Hashimoto

    It is well known that ground vibration by blasting is mainly related to a distance and charge weight. However, it is not known the correlation between ground vibration and performances of explosives;

    Prediction and Determination of Explosive-Induced Fracture

    By J R. Hearst, T R. Butkovich

    Explosive-induced fracturing and permeability enhancement far from a free face were studied. A one-dimensional computer program, SOC, was used to predict the total failure-associated distortional stra

    Increased Blasting Efficiency Through Operational and Geological Controls on Ore Particle Size

    By W. Boas, R. Silva, D. Yumi, L. Steffen

    The continuity of the flow and stages within the mining process is essential to achieve success in its operation and results, especially when it comes to a gold mine. During the first seven months of

    Sources of Variability in Rock Hardness During Crater Blasting

    By Bradley C. Paul

    Similar rock formations exhibit great variability in resistance to fragmentation during crater blasting. This observation was made during an attempt to calibrate the Kuz-Ram blast fragmentation model

    Rugged Emulsion Explosive Formulation #37 - Candidate Permissible

    By Michael S. Wieland, Thomas C. Ruhe

    Delay blasting in underground coal results in shock waves traveling through the coal that can damage delay charges remaining in the blast pattern. Undetonated explosives which are dynamically desensit

    Fragmentation Control Through the Attenuation of Explosively Produced Shock Waves

    By S B. Richardson, N T. Moxon, A C. Torrance

    In many mining situations the energy released by an explosive is far too high and results in over fragmentation and excessive damage to the surrounding strata. Laboratory experiments have demonstrated

    The Origins and Effects of Inter-deck Pressure in Decked Blasts

    By J. A. Rodgers, K. C. Whitaker

    The time domain during which an explosive detonates and causes rock to fragment and displace is on the order of tens of milliseconds. Because of this, the dynamic processes that occur during this time
