Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The purpose of this book is to introduce the students, geologists, and engineers to the fundamentals of the finite element method and its application in the field of geotechnical engineering with emphasis on rock mechanics. They learn the necessary principles to help them use commercially available programs or to create their own basic finite element code for the stress and deformation analysis of solid structures. The topics covered in this book are: Introduction to numerical methods, displacement Finite element method, equilibrium equations, elasticity relations, formulation procedure (solid mechanics), shape functions, stiffness matrix, load vectors, mesh convergence and accuracy, isoparametric element and numerical integration.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Many Canadian underground mines use longitudinal and transverse stoping with delayed backfill to extract tabular ore deposits. These methods require access to the orebody through a number of sill drives or cross-cuts which link the orezone to the haulage drift hence creating intersections on multiple levels. This study is the first to attempt stochastic methods with numerical analysis to mine developments for the purpose of evaluating their stability performance with respect to planned mining sequence. Consequently, a qualitative method is developed to estimate the risk level (e.g. rating and ranking) resulting from mining activity. Risk is the product of probability of failure and cost of consequences. A resultant assessment scale matrix (e.g., a 5-level risk index is derived which ranges from low to extreme) is then used to assign a risk index value which is directly proportional to the potential for excavation instability. The methodology is demonstrated through a case study (e.g., the No. 1 Shear East orebody at Vale's Garson Mine in Sudbury, Ontario). Finally, the risk indexing tool can be used to confirm the need for enhanced supports and to compare alternative mine designs 268 pp. Englisch.…
