Effect of air column in transport canisters on measured gas contents of coal

N. Aziz; A. Mirzaghorbanali

Volume 8, Issue 1 , January 2017, Pages 1-9


  Canister desorption is a widely used technique to measure the gas content of coal. The gas content data, when normalized to volume/weight and multiplied by coal seam mass, is used to estimate the gas in place in an area around the cored hole. However, the gas content and the percentage of each constituent ...  Read More

Case Study
Operational dynamics of “Galamsey” within eleven selected districts of western region of Ghana

J. Mantey; F. Owusu-Nimo; K.B. Nyarko; A. Aubynn

Volume 8, Issue 1 , January 2017, Pages 11-34


  The uncontrolled spread of illegal artisanal small-scale gold mining (ASM), popularly termed “galamsey” in Ghana, has, for decades, impacted adversely upon water bodies, soils, wildlife, human health, and safety. A lack of understanding, however, of the types of galamsey, their operational ...  Read More

Case Study
Use of artificial intelligence techniques to predict distribution of heavy metals in groundwater of Lakan lead-zinc mine in Iran

Z. Bayatzadeh Fard; F. Ghadimi; H. Fattahi

Volume 8, Issue 1 , January 2017, Pages 35-48


  Determining the distribution of heavy metals in groundwater is important in developing appropriate management strategies at mine sites. In this paper, the application of artificial intelligence (AI) methods to data analysis,namely artificial neural network (ANN), hybrid ANN with biogeography-based optimization ...  Read More

Case Study
A new model for mining method selection based on grey and TODIM methods

H. Dehghani; A. Siami; P. Haghi

Volume 8, Issue 1 , January 2017, Pages 49-60


  One of the most important steps involved in mining operations is to select an appropriate extraction method for mine resources. After choosing the extraction method, it is usually impossible to replace it with another one because it may be so expensive that implementation of the entire project could ...  Read More

Case Study
Rock mass structural data analysis using image processing techniques (Case study: Choghart iron ore mine northern slopes)

M. Mohebbi; A.R. Yarahmadi Bafghi; M. Fatehi Marji; J. Gholamnejad

Volume 8, Issue 1 , January 2017, Pages 61-74


  Presence of joints and fractures in rocks strongly influences the behavior of the rock mass by dividing the media into smaller units. These structures intensify the potential instability besides the development of sliding and rotational movements. The assumption of discontinuum media changes the whole ...  Read More

Case Study
Investigation of parameters affecting desilication of diasporic bauxite in Jajarm mine by thermo-chemical treatment

M. Rezaee Rad; Sh. Shahhoseini; M. Janfada; H. A. Mirzaee; P. Kelidari

Volume 8, Issue 1 , January 2017, Pages 75-81


  Low grade diasporic bauxite in the Jajarm mine with an A/S (Al2O3/SiO2) ratio of 2.3 is not usable in the Bayer process at Jajarm Alumina Complex. Due to the severe interlocking effect between the diaspore and aluminosilicate minerals (Chamosite and Kaolinite) and iron-containing minerals in a microcrystal ...  Read More

Case Study
A new brittleness index for estimation of rock fracture toughness

H. R. Nejati; Seyed A. Moosavi

Volume 8, Issue 1 , January 2017, Pages 83-91


  Assessment of the correlation between rock brittleness and rock fracture toughness has been the subject of extensive research works in the recent years. Unfortunately, the brittleness measurement methods have not yet been standardized, and rock fracture toughness cannot be estimated satisfactorily by ...  Read More

Case Study
Determining fractal parameter and depth of magnetic sources for ardabil geothermal area using aeromagnetic data by de-fractal approach

A. Khojamli; F. Doulati Ardejani; A. Moradzadeh; A. Nejati Kalateh; A. Roshandel Kahoo; S. Porkhial

Volume 8, Issue 1 , January 2017, Pages 93-101


  The Ardabil geothermal area is located in the northwest of Iran, which hosts several hot springs. It is situated mostly around the Sabalan Mountain. The Sabalan geothermal area is now under investigation for the geothermal electric power generation. It is characterized by its high thermal gradient and ...  Read More

Detection and determination of groundwater contamination plume using time-lapse electrical resistivity tomography (ERT) method

S. Moghaddam; S. Dezhpasand; A. Kamkar Rohani; S. Parnow; M. Ebrahimi

Volume 8, Issue 1 , January 2017, Pages 103-110


  Protection of water resources from contamination and detection of the contaminants and their treatments are among the essential issues in the management of water resources. In this work, the time-lapse electrical resistivity tomography (ERT) surveys were conducted along 7 longitudinal lines in the downstream ...  Read More

Case Study
Evaluation of structural analysis of tunnel segmental lining using beam-spring method and force-method (Case study: Chamshir water conveyance tunnel)

M. Nikkhah; Seyed S. Mousavi; Sh. Zare; O. Khademhosseini

Volume 8, Issue 1 , January 2017, Pages 111-130


  The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms ...  Read More
