Adaptive Multi-Size Block Modeling for Mineral Resources and Ore Reserves Evaluation

F. Khorram; O. Asghari; H. Memarian; A. Hoseein Morshedy; X. M. Emery

Volume 12, Issue 2 , April 2021, , Pages 339-350


  The key input parameters for mine planning and all subsequent mining activities is based on the block models. The block size should take into account for the geological heterogeneity and the grade variability across the deposit. Providing grade models of smaller blocks is more complex and costly than ...  Read More

Development of a New Experimental Technique for Dynamic Fracture Toughness Measurement of Rocks using Drop Weight Test

Gh. Khandouzi; H. Memarian; M. H. Khosravi

Volume 11, Issue 3 , July 2020, , Pages 909-920


  The dynamic fracture characteristics of rock specimens play an important role in analyzing the fracture issues such as blasting, hydraulic fracturing, and design of supports. Several experimental methods have been developed for determining the dynamic fracture properties of the rock samples. However, ...  Read More

A comparison between effects of earthquake and blasting on stability of mine slopes: a case study of Chadormalu open-pit mine

R. Shafiei Ganjeh; H. Memarian; M. H. Khosravi; M. Mojarab

Volume 10, Issue 1 , January 2019, , Pages 223-240


  Dynamic slope stability in open-pit mines still remains a challenging task in the computational mining design. Earthquake and blasting are two significant sources of dynamic loads that can cause many damages to open-pit mines in active seismic areas and during exploitation cycles. In this work, the effects ...  Read More

Determination of scratching energy index for Cerchar abrasion test

M. T. Hamzaban; H. Memarian; J. Rostami

Volume 9, Issue 1 , January 2018, , Pages 73-89


  Rock abrasivity is an essential factor for selecting cutting tools, estimating tool wear and life, and ultimately, matching various mechanized excavation systems with a given geologic condition. It also assists engineers to determine economic limits of different cutting tools and machines used in civil ...  Read More

Application of Bayesian decision making tool in detecting oil-water contact in a carbonate reservoir

Amir Mollajan; Hossein Memarian; Behzad Tokhmechi

Volume 5, Issue 2 , July 2014, , Pages 91-97


  Detection of Oil-Water Contacts (OWCs) is one of the primary tasks before evaluation of reservoir’s hydrocarbon in place, determining net pay zones and suitable depths for perforation operation. This paper introduces Bayesian decision making tool as an effective technique in OWC detecting using ...  Read More

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
