Hekmatnejad, Amin; Emery, Xavier; Elmo, Davide (Elsevier Ltd, 2019)© 2018 Elsevier Ltd This work addresses the problem of parameter inference in the Cox-Boolean discrete fracture network model, in which the fractures are represented by flat discs with random orientations and diameters ...

Hekmatnejad, Amin; Emery, Xavier; Alipour-Shahsavari, Mehrnoosh (Taylor and Francis Ltd., 2019)© 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. Ore/waste classification and economic evaluations of mineral deposits rely on the grade of elements of interest, which must be predicted as accurately ...

Hekmatnejad, Amin (Universidad de Chile, 2018)La caracterización de fracturas es crítica en minería a cielo abierto y subterránea, así como en ingeniería geológica e ingeniería de petróleo, para comprender las propiedades mecánicas e hidráulicas del macizo rocoso. ...

Hekmatnejad, Amin; Crespin, Benoit; Opazo, Álvaro; Emery, Xavier; Hitschfeld-Kahler, Nancy; Elmo, Davide (Pergamon-Elsevier, 2020)The purpose of this work is to highlight the impact of input parameters uncertainty in discrete fracture network (DFN) models and their engineering applications. We show how the error of an input parameter, here the ...

Hekmatnejad, Amin; Emery, Xavier; Vallejos, Javier A. (Elsevier SCI Ltd, 2018)A distribution-free approach is proposed to estimate the fracture size distribution from a given trace length distribution, assuming that the fracture network can be represented by a Poisson-disc model. This approach ...

Hekmatnejad, Amin; Emery, Xavier; Brzovic, Andrés; Schachter, Paulina; Vallejos Massa, Javier (Elsevier, 2017)This work addresses the problem of predicting the discontinuity intensity P32 (discontinuity area per unit volume of rock mass) in space and of quantifying the uncertainty in the true P32 values, using information from ...
