(International Journal of Coal Science and Technology, 2016-12-17)Conventionally, mining industry relies on a deterministic view, where a unique mine plan is determined based on a single resource model. A major shortfall of this approach is the inability to assess the risk caused by the ...
-
(Wires Water, 2017)Water resources in Central Asia are scarce, so complicated issues arise from this. Kazakhstan is a Central Asian landlocked country, which has mostly closed drainage basins, characterized by endorheic lakes that do not ...
-
(Engineering Geology, 2017-08-30)Abstract One of the essential tasks in the excavation of tunnels with TBM is the reliable estimation of its performance needed for the planning, cost control and other decision making on the feasibility of the tunneling ...
-
(The 26th International Symposium on Mine Planning and Equipment Selection, 2017-08-31)Geostatistical methods have been increasingly used as powerful techniques for predicting spatial attributes and modelling the uncertainty of predictions in un-sampled locations, especially through multi-element deposits. ...
-
(Resources Policy, 2017-11-10)Abstract Geological uncertainty represents an inherent threat for all mining projects. Mining operations utilise resource block models as a primary source of data in planning and in decision making. However, such operational ...
-
(25th World Mining Congress 2018. Proceedings. Geological Exploration., 2018)Geometallurgical variables have a significant impact in downstream activities of mining projects. Reliable 3D spatial modelling of these variables play an important role in mine planning and mineral processing, in which ...
-
(25th World Mining Congress 2018. Proceedings. Geological Exploration., 2018)Geostatistical modeling of Iron grade (Fe) in metalliferous deposits is a rationale stage in further analysis of mine design such as mine planning and mineral processing plant optimization. This procedure is becoming ...
-
(Geological Exploration: 85-96, 2018)Geostatistical modeling of Gold grade (Au) is challenging since the presence of outliers makes the distribution long-tailed and impacts significantly the process of mineral resource evaluation, the mine design and financial ...
-
(Natural Resources Research, 2018)Fractal/multifractal modeling is a widely used geomathematical approach to capturing different populations in geochemical mapping. The rationale of this methodology is based on empirical frequency density functions ...
-
(Energies, doi:10.3390/en11020292, 2018-01-28)Thermal oil recovery techniques, including steam processes, account for more than 80% of the current global heavy oil, extra heavy oil, and bitumen production. Evaluation of Naturally Fractured Carbonate Reservoirs (NFCRs) ...
-
(Energies 2018, 2018-02-01)In this paper, we characterized the natural fracture systems and inferred the state of in situ stress field through an integrated study in a very complex and heterogeneous fractured carbonate heavy oil reservoir. Relative ...
-
(Natural Resources Research, 2018-04)With a mining-driven economy, Botswana has experienced increased geochemical exploration of minerals around existing mining towns. The mining and smelting of copper and nickel around Selibe-Phikwe in the Central Province ...
-
(Frontiers, 2018-05-22)Lake Dziani Dzaha is a thalassohaline tropical crater lake located on the “Petite Terre” Island of Mayotte (Comoros archipelago, Western Indian Ocean). Stromatolites are actively growing in the shallow waters of the lake ...
-
(Journal of the Southern African Institute of Mining and Metallurgy, 2018-07-01)Mathematical programming has been applied to optimizing open pit mine planning problems since the early 1960s. Nonetheless, it still remains challenging to obtain a life-of-mine plan with current computational hardware and ...
-
(ELSEVIER, 2018-07-05)Low salinity water is an emerging enhanced oil recovery (EOR) method that causes wettability alteration towards a favorable state to reduce residual oil saturation, while water alternating gas (WAG) is a proven EOR process ...
-
(Stochastic Environmental Research and Risk Assessment, 2018-07-06)Cokriging allows predicting coregionalized variables from sampling information, by considering their spatial joint depen- dence structure. When secondary covariates are available exhaustively, solving the cokriging equations ...
-
(The Southern African Institute of Mining and Metallurgy, 2018-08)The quantification and classification of mineral resources and ore reserves is often based on an assessment of the certainty (or uncertainty) of the estimates of tonnage and grade of elements of interest (metals and ...
-
(Geometallurgy Conference 2018, Back to the Future Cape Town, (6-8 August 2018). The Southern African Institute of M ining and Metallurgy, 2018-08-06)Several geomechanical variables reflect the characteristics of rock masses and in recent years have been considered as the geometallurgical responses in the mining industry. These variables have a great effect on the ...
-
(Journal of Petroleum Exploration and Production Technology, 2018-08-14)Deterministic modeling lonely provides a unique boundary layout, depending on the geological interpretation or interpolation from the hard available data. Changing the interpreter’s attitude or interpolation parameters ...
-
(SPRINGER HEIDELBERG, 2018-10-12)Application of polymer flooding in high temperature–high salinity (HTHS) carbonate reservoirs is challenging due to lack of polymers that can withstand such harsh reservoir conditions. The traditional polymers are usually ...
