Porosity classification from thin sections using image analysis and neural networks including shallow and deep learning in Jahrum formation (Shahrood University of Technology, 2018-04-01)The porosity within a reservoir rock is a basic parameter for the reservoir characterization. The present paper introduces two intelligent models for identification of the porosity types using image analysis. For this aim, ...
 
- 
A practical approach to open-pit mine planning under price uncertainty using information gap decision theory (Shahrood University of Technology, 2018-04-01)In the context of open-pit mine planning, uncertainties including commodity price would significantly affect the technical and financial aspects of mining projects. A mine planning that takes place regardless of the ...

Random forests algorithm in podiform chromite prospectivity mapping in Dolatabad area, SE Iran (Shahrood University of Technology, 2018-04-01)The Dolatabad area located in SE Iran is a well-endowed terrain owning several chromite mineralized zones. These chromite ore bodies are all hosted in a colored mélange complex zone comprising harzburgite, dunite, and ...
 
- 
Removal of Te and Se anions in alkaline media in presence of cyanide by quaternary ammonium salts (Shahrood University of Technology, 2018-04-01)Precious metals are currently associated with selenium (naumannite, Ag2Se) and tellurium (calaverite, AuTe2; sylvanite, (Au,Ag)2Te4) to form species refractory to cyanidation. ...
 
- 
Stability analysis of support systems using a coupled FEM-DFN model (Case study: a diversion tunnel at Lorestan dam site, Iran) (Shahrood University of Technology, 2018-04-01)Various structural discontinuities, which form a discrete fracture network, play a significant role in the failure conditions and stability of the rock masses around underground excavations. Several continuum numerical ...
