Comments on Corner Fracture in Rock caused by Blasting with Two Free Faces

Numerical Analysis of the Primer Location Effect on Ground Vibration Caused by Blasting

Ground vibration is one of the undesirable results of blasting operations. Different methods have been proposed to predict and control ground vibration that is caused by blasting. These methods can be classified as laboratory studies, fieldwork and numerical modeling. Among these methods, numerical modeling is the one which saves time and cuts costs since it takes into account the basic princip...

Acoustic Emissions Produced by Discrete Fracture in Rock

An experimental programme was undertaken to develop a servo-controlled loading and high-fidelity data acquisition system to ~westigate acoustic emission (AE) waveforms produced during discrete fracture propagation in rock. Large (0.3 × 0.3 × I m) chevron-notched specimens were loaded in controlled conditions, and characteristic acoustic emissions associated with Mode I and Mode l l fracture wer...

Implementation of Hyperbolic Tangent Function to Estimate Size Distribution of Rock Fragmentation by Blasting in Open Pit Mines

Rock fragmentation is one of the desired results of rock blasting. So, controlling and predicting it, has direct effects on operational costs of mining. There are different ways that could be used to predict the size distribution of fragmented rocks. Mathematical relations have been widely used in these predictions. From among three proposed mathematical relations, one was selected in this stud...
