Numerical modelling in mining SlideShare

Numerical modelinganalysis with the help of FLAC-3Dfacilitates the mining engineer to foresee themining process & to know the behavior of the rock after every stage of mining likedevelopment & stoping. The main objective of numerical modeling is to simulatethe mining scenario & to predict the behavior and the effect of stress distributionwithout actually performing the mining in

Applications of numerical modelling in underground

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 and shaft.

Numerical modelling approach for mine backfill

Abstract. Numerical modelling is broadly used for assessing complex scenarios in underground mines, including mining sequence and blast-induced vibrations from production blasting. Sublevel stoping mining methods with delayed backfill are extensively used to exploit steeply dipping ore bodies by Canadian hard-rock metal mines. Mine backfill is an important constituent of mining process. Numerical

Numerical Modelling an overview ScienceDirect Topics

Numerical modeling is at present widely used to simulate the behavior of rockmass with or without rockbolting in various geotechnical projects. The numerical methods used in modeling of geomaterials include finite element method (FEM), boundary element method (BEM), finite difference method (FDM), and discrete element method (DEM).
