Geovariances’ scientific rigour, continuous innovation and geostatistical expertise guarantee the quality of your evaluations at different stages of the development of your projects (feasibility studies, bankable studies, desktop reviews, etc.).Estimating mineral resources is performed at all stages of the mine life cycle.Geostatistics will ensure you get the maximum value out of the available information: investigate data quality, focus on the reliable data, discount unreliable, erroneous data and produce accurate resource estimates.Maximise the return on your data investment and then use the results to optimise future data collection.Geostatistics can help assuring they are fit for the purpose of producing a MRE you can trust by focusing on: – Statistical Homogeneity – Boundary Analysis and Boundary Treatment – Domain Combination or Sub-division This is the only way you can ensure the estimation methodology you use will be completely adapted to the deposit you are modeling: – Exploratory Data Analysis – Experimental Variography – Data transforms – Variogram Modeling – Cross-Validation – Exploration – Feasibility – Grade Control A sound evaluation of Recoverable Resources is a pre-requisite for Reserve Calculation.They help determine the portion of the deposit that is technically recoverable when one applies a cut-off to selective mining units (SMU’s) to be mined at production stage.These finite element models are mostly based on the design drawings and nominal material properties.
In this analysis we focus on stochastic kriging metamodels.
When a prediction for a new input is required the procedure is to augment the metamodel forecast with additional simulation outputs for a given input.
The key benefit of the method is that it is possible to reach the desired prediction accuracy at a new input faster than in the case when no initial metamodel is present.
A common method is by predicting the deflections of the bridge during each construction phase through the associated finite element models.
Therefore, the cambers of the bridge during different construction phases can be determined beforehand.
