Case Study
Extension of Excavation Damaged Zone Due to Longwall Working Effect

H. Mohammadi; M. A. Ebrahimi Farsangi; H. Jalalifar; A. R. Ahmadi; A. Javaheri

Volume 7, Issue 1 , January 2016, Pages 13-24


  In advance longwall mining, the safety of mine network, production rate, and consequently, economic conditions of a mine are dependent on the stability conditions of gate roadways. The gate roadway stability is a function of two important factors: 1) characteristics of the excavation damaged zone (EDZ) ...  Read More

Case Study
Probabilistic analysis of stability of chain pillars in Tabas coal mine in Iran using Monte Carlo simulation

M. Najafi; Seyed M. E. Jalali; F. Sereshki; A. Yarahmadi Bafghi

Volume 7, Issue 1 , January 2016, Pages 25-35


  Performing a probabilistic study rather than a determinist one is a relatively easy way to quantify the uncertainty in an engineering design. Due to the complexity and poor accuracy of the statistical moment methods, the Monte Carlo simulation (MCS) method is wildly used in an engineering design. In ...  Read More

Case Study
Development of a mechanical earth model in an Iranian off-shore gas field

E. Bozorgi; D. Javani; M. Rastegarnia

Volume 7, Issue 1 , January 2016, Pages 37-46


  Wellbore instability is a quite common event during drilling, and causes many problems such as stuck pipe and lost circulation. It is primarily due to the inadequate understanding of the rock properties, pore pressure, and earth stress environment prior to well construction. This study aims to use the ...  Read More

Original Research Paper
A New Approach for Obtaining Settling Velocity in a Thickener Using Statistical Regression: A Case Study

M. Hosseini Nasab

Volume 7, Issue 1 , January 2016, Pages 47-56


  In this research work, the parameters affecting the settling velocity within the thickeners were studied by introducing an equivalent shape factor. Several thickener feed samples of different densities including copper, lead and zinc, and coal were prepared. The settling tests were performed on the samples, ...  Read More

Case Study
Negative impacts of mine exploitations on rural regions of Tekab Township

Gh. Mojarradi; R. Rezaei; A. Ketabi

Volume 7, Issue 1 , January 2016, Pages 57-66


  This descriptive analytical survey was aimed to study the negative impacts of mine exploitations carried out in the rural regions of the Tekab Township located in Iran. The statistical population of the studied areas consisted of all the heads of the rural households in the villages located in the vicinity ...  Read More

Case Study
Joint inversion of ReMi dispersion curves and refraction travel times using particle swarm optimization algorithm

A. Zarean; R. Poormirzaee

Volume 7, Issue 1 , January 2016, Pages 67-79


  Shear-wave velocity ( ) is an important parameter used for site characterization in geotechnical engineering. However, dispersion curve inversion is challenging for most inversion methods due to its high non-linearity and mix-determined trait. In order to overcome these problems, in this study, a joint ...  Read More

Estimation of Cadmium and Uranium in a stream sediment from Eshtehard region in Iran using an Artificial Neural Network

F. Razavi Rad; F. Mohammad Torab; A. Abdollahzadeh

Volume 7, Issue 1 , January 2016, Pages 97-107


  Considering the importance of Cd and U as pollutants of the environment, this study aims to predict the concentrations of these elements in a stream sediment from the Eshtehard region in Iran by means of a developed artificial neural network (ANN) model. The forward selection (FS) method is used to select ...  Read More

Research Note
