Assessment of natural attenuation of acid mine drainage pollutants in El Bierzo and Odiel basins: A case study

Prof R.N. Singh; O Aduvire; V.F Navarro Torres

Volume 2, Issue 2 , July 2011, Pages 78-85


  In the past, mining activities have generated major acid drainage sources, which usually carry dissolved metals that flow into the main rivers of the affected basins. The study looks at natural attenuation processes in local, sub-basin and basin areas, in the El Bierzo and Odiel basins of Spain, where ...  Read More

Investigation of blind massive sulphide deposit signatures in the calcrete layers as a geochemical barrier: A case study of Areachap, Kantienpan and Copperton deposits

Reza Ghavami-Riabi; H.F.J Theart

Volume 2, Issue 2 , July 2011, Pages 86-101


  The trace element contents on the surface originated from mineralization would depend to the thickness of the calcrete layer above the ore deposit on the surface. A very thick layer of calcrete may not allow for much dispersion of the elements of interest in the surface. These elements may be concentrated ...  Read More

On the reduction of the ordinary kriging smoothing effect

H. Rezaee; O. Asghari; J.K. Yamamoto

Volume 2, Issue 2 , July 2011, Pages 102-117


  A simple but novel and applicable approach is proposed to solve the problem of smoothing effect of ordinary kriging estimate which is widely used in mining and earth sciences. It is based on transformation equation in which Z scores are derived from ordinary kriging estimates and then rescaled by the ...  Read More

A new algorithm for optimum open pit design: Floating cone method III

ebrahim elahi; Reza Kakaie; amir yusefi

Volume 2, Issue 2 , July 2011, Pages 118-125


  Ultimate limits of an open pit, which define its size and shape at the end of the mine’s life, is the pit with the highest profit value. A number of algorithms such as floating or moving cone method, floating cone method II and the corrected forms of this method, the Korobov algorithm and the corrected ...  Read More

Original Research Paper
Limestone chemical components estimation using image processing and pattern recognition techniques

F. Khorram; H. Memarian; B. Tokhmechi; H. Soltanian-zadeh

Volume 2, Issue 2 , July 2011, Pages 126-135


  In this study based on image analysis, an ore grade estimation model was developed. The study was performed at a limestone mine in central Iran. The samples were collected from different parts of the mine and crushed in size from 2.58 cm down to 15 cm. The images of the samples were taken in appropriate ...  Read More

Relationship between fracture dip angle, aperture and fluid flow in the fractured rock masses

Mohammad Fatehi; Arash Pashapour; Javad Gholamnejad

Volume 2, Issue 2 , July 2011, Pages 136-145


  Most of the Earth's crust contains fluids, and fractures are common throughout the upper part. They exist at a wide range of scales from micro-fractures within grains to major faults and shear zones that traverse the crust. In this paper, the stress-dependent permeability in fractured rock masses have ...  Read More

Estimating the deformation modulus of jointed rock mass under multilateral loading condition using analytical methods

M Ebadi; Saeed Karimi Nasab; H Jalalifar

Volume 2, Issue 2 , July 2011, Pages 146-156


  rnDetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. In-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. However, these methods are very expensive ...  Read More
