Groundwater Modelling for Mining 2 - Numerical Modelling covers set-up of a numerical model, model calibration and verification, modelling predictions, and evaluation of model uncertainty The course comprises ten learning sessions of 30 to 60 minutes each, several case studies, and interactive reviews that confirm achievement of the learning objectiv
Case Studies of Parametric Assessments Using …
Hoek (1991) recommended engineers use parametric studies as habit to forecast the performance of geotechnical designs and Wiles (2005) later described the reliability of numerical modelling and probability-based outcomes using several mining case studies. Despite numerical modelling being routinely undertaken for rock mechanics problems, multi-parametric assessments to characterize …
Applications of numerical modelling in …
01.09.1999 · Numerical modelling has been used to investigate a variety of problems in underground mining and tunnelling: subsidence induced by longwall coal mining; stresses generated when an open stope is filled cemented backfill and the stability of exposures created during subsequent mining of adjacent stopes; the interaction of two tunnels; and the effects of under-mining a pre-existing tunnel …
GROUNDWATER FLOW MODELLING APPLICATIONS IN MINING …
In the presented stone some specific features and problems of numerical modelling applications in mining environment are briefly discussed. The issues discussed are documented by three modelling case studies. Two of the applications are aimed at mine dewatering problems in active coal mines. The first represents the underground hard coal mining region in the Czech part of the Upper Silesian ...

Esen Mining Consulting | Case Studies
These studies have shown that all the processes in the Mine to Mill value chain are inter-dependent and the results of the upstream mining processes have a significant impact on the efficiency of downstream milling processes such as crushing and grinding. Numerous Mine to Mill projects to date resulted in mill throughput increases of between 5 and 30 % depending on the ore strength and ...
Paper: Using numerical modelling to represent …
Numerical models have an advantage over empirical methods when it comes to understanding the physics of a rock mechanics problem such as caving geomechanics. In using numerical modelling, various hypotheses can be tested and compared to the actual behaviour of the rock mass response to caving. Predicting rock mass caveability remains a ...
Strength, fallouts and numerical modelling of hard rock masses
evaluated through three case studies. A Round Robin Test was conducted for two of these cases. The evaluation was performed in order to identify robust systems and criteria, as well as to identify the parameters having the strongest impact on the calculated rock mass strength. The case studies revealed that the N, Yudhbir – RMR 76,
The Utilisation of Numerical Modelling to Predict …
This stone illustrates how numerical modelling has been utilised to predict water and gas pathways around active longwall panels using two case studies. This information has proved invaluable m the design of methane drainage schemes and for risk assessments undertaken at the mining planning stage. The modelling approach described has now been applied successfully to several situations in UK ...
