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...
متن کاملApplication of Confined Blasting in Water-Filled Deep Holes to Control Strong Rock Pressure in Hard Rock Mines
In extra-thick coal seams, mining operations can lead to large-scale disturbances, complex overburden structures, and frequent and strong strata behavior in the stope, which are serious threats to mine safety. This study analyzed the overburden structure and strata behavior and proposed the technique of confined blasting in water-filled deep holes as a measure to prevent strong rock pressure. I...
متن کاملSlope Stability Analysis for Open Pits
In the process of wall design for open pits, a number of steps and levels of analyses are required, from local bench design to overall stability of the walls, to evaluation of the design performance and calibration of parameters through back-analysis. This process requires the use of a variety of methods of analysis and software ranging from limit equilibrium methods to more involved numerical ...
متن کاملSensitivity Analysis of Stress and Cracking in Rock Mass Blasting using Numerical Modelling
Drilling and blasting have numerous applications in the civil and mining engineering. Due to the two major components of rock masses, namely the intact rock matrix and the discontinuities, their behavior is a complicated process to be analyzed. The purpose of this work is to investigate the effects of the geomechanical and geometrical parameters of rock and discontinuities on the rock mass blas...
متن کاملBlasting Open a Choice Space: Learning Inflectional Morphology for NLP
This article discusses the various aspects of designing a system for eliciting knowledge about language from informants. For each design aspect, various options for implementation are presented, along with their pros, cons, and repercussions for other parts of the knowledge elicitation system. A running example throughout the text is taken from the paradigmatic morphology elicitation module of ...
