Cavability Assessment of Rock Mass in Block Caving Mining Method based on Numerical Simulation and Response Surface Methodology

B. Alipenhani; A. Majdi; H. Bakhshandeh Amnieh

Volume 13, Issue 2 , April 2022, , Pages 579-606


  The present work aims at implementing Response Surface Methodology (RSM) in order to generate a statistical model for Minimum Required Caving Span (MRCS) and estimate both the individual and mutual effects of the rock mass parameters on rock mass cavability. The adequate required data is obtained from ...  Read More

Determination of Caving Hydraulic Radius of Rock Mass in Block Caving Method using Numerical Modeling and Multivariate Regression

B. Alipenhani; A. Majdi; H. Bakhshandeh Amnieh

Volume 13, Issue 1 , January 2022, , Pages 217-233


  Determining the hydraulic radius of the undercut in the block caving method is one of the key issues in this method. The hydraulic radius is directly related to the minimum caving span. In this research work, the rock mass cavability is investigated using the UDEC and 3DEC software. Since the factors ...  Read More

Application of simulated annealing for optimization of blasting costs due to air overpressure constraints in open-pit mines

H. Bakhshandeh Amnieh; M. Hakimiyan Bidgoli; H. Mokhtari; A. Aghajani Bazzazi

Volume 10, Issue 4 , October 2019, , Pages 903-916


  Estimating the costs of blasting operations is an important parameter in open-pit mining. Blasting and rock fragmentation depend on two groups of variables. The first group consists of mass properties, which are uncontrollable, and the second one is the drill-and-blast design parameters, which can be ...  Read More

Numerical analysis of energy transmission through discontinuities and fillings in Kangir Dam

A. Siamaki; H. Bakhshandeh Amnieh

Volume 7, Issue 2 , July 2016, , Pages 251-259


  A considerable amount of energy is released in the form of shock wave from explosive charge detonation. Shock wave energy is responsible for the creation of crushing and fracture zone around the blast hole. The rest of the shock wave energy is transferred to rock mass as ground vibration. Ground vibration ...  Read More
