Overburden management in open pits: options and limits in large limestone quarries

引用

International Journal of Mining Science and Technology 2019年第2期29卷 217-228页

作者： claudio Oggeri Taddeo Maria Fenoglio Alberto Godio Raffaele Vinai Department of Environment Land and Infrastructure Engineering Politecnico di Torino College of Engineering Mathematics and Physical Sciences University of Exeter

The management of overburden is an important task in open pit exploitations. Site topography and morphology as well as geological and geotechnical properties of natural and remoulded materials are the most important factors affecting the disposal phase. Economic and environmental requirements must be followed in order to achieve the best reclamation results, keeping into account site constraints such as slope stability, hauling and dumping issues, and interactions with groundwater. This paper deals with the above mentioned issues, illustrating a rational approach applied on the case of a large limestone quarry where the thickness of the overburden is relevant and the spoil material has to be dumped in a flooded pit. The proposed multidisciplinary approach led to the selection of most suitable methods for excavation, transportation and disposal. The selection was based on a detailed laboratory and site characterisation that defined favorable and adverse factors to be considered during the preliminary study of a large quarrying project.

An Adaptive hp-DG-FE Method for Elliptic Problems: Convergence and Optimality in the 1D Case

引用

Communications on Applied Mathematics and Computation 2019年第3期1卷 309-331页

作者： Paola Antonietti claudio Canuto Marco Verani MOX-Dipartimento di Matematica Politecnico di MilanoP.zza Leonardo Da Vinci 3220133 MilanItaly Dipartimento di Scienze Matematiche Politecnico di TorinoCorso Duca degli Abruzzi 2410129 TurinItaly

We propose and analyze an hp-adaptive DG-FEM algorithm, termed hp-ADFEM, and its one-dimensional realization, which is convergent, instance optimal, and h- and p-robust. The procedure consists of iterating two routines:one hinges on Binev's algorithm for the adaptive hp-approximation of a given function, and finds a near-best hp-approximation of the current discrete solution and data to a desired accuracy;the other one improves the discrete solution to a finer but comparable accuracy, by iteratively applying D?rfler marking and h refinement.

Development of AI-and Cu-based nanocomposites reinforced by graphene nanoplatelets： Fabrication and characterization

引用

Frontiers of Materials Science 2017年第2期11卷 171-181页

作者： Abdollah SABOORI Matteo PAVESE claudio BADINI Paolo FINO Department of Applied Science and Technology Politecnico Di Torino Corso Duca Degli Abruzzi 24 10129 Torino Italy

Aluminum and copper matrix nanocomposites reinforced by graphene nanoplatelets （GNPs） were successfully fabricated by a wet mixing method followed by conventional powder metallurgy. The uniform dispersion of GNPs within the metal matrices showed that the wet mixing method has a great potential to be used as a mixing technique. However, by increasing the GNPs content, GNPs agglomeration was more visible. DSC and XRD of AI/GNPs nanocomposites showed that no new phase formed below the melting point of AI. Microstructural observations in both nanocomposites reveal the evident grain refinement effect as a consequence of GNPs addition. The interfacial bonding evaluation shows a poor interfacial bonding between GNPs and AI, while the interfacial bonding between Cu and GNPs is strong enough to improve the properties of the Cu/GNPs nanocomposites. In both composites, the coefficient of thermal expansion decreases as a function of GNPs while, their hardness is improved by increasing the GNPs content as well as their elastic modulus.
