Jun 23, 2019 Jun 23, 2019 Parametric assessments using numerical models are not new in rock mechanics and described as far backs as the 1980's. However, the uptake of parametrical assessments using numerical modelling for design and sensitivity assessments in the mining industry has not kept pace with advances in computing power

Mine Design and Numerical Modeling Laboratory - McGill

Three-dimensional models of the case study mining block are constructed to examine drift stresses associated with individual stope recovery as the mining block is extracted. Model results include stress distribution around the drift, extent of yield zones as well as drift deformation profiles. In stage 4, numerical modelling results are validated with well documented field observations and monitoring

Ground Water Flow Modelling Applications in Mining

Ground Water Flow Modelling Applications in Mining

Oct 16, 2007 Some specific features and problems of numerical modelling applications in mining environment are briefly discussed and three modelling case studies are presented. 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 Coal Basin. The second

Extending empirical evidence through numerical

numerical models is demonstrated. The first case examines the analysis of discontinuity effects on the strength of slender pillars in limestone mines, and the second case evaluates the effects of stress orientation on coal mine entry stability. It is concluded that numerical model calibration and verifi
