... theory (Kirchoff 1850, Timoshenko & Krieger 1982). The plate is resting on a foundation and subjected to a uniformly distributed surface load q (i.e. weight of the flooded overburden rock mass) The Winkler model (Timoshenko & Krieger 1982) is accepted as the simplest but most widely known foundation...

...1 INTRODUCTION As part of a study on cemented rock fill (CRF) spans in underground mines, laboratory testing of CRF beams was conducted. Additional laboratory testing was performed on CRF samples to determined ma- terial properties to be used in the construction of numerical models of the tested...

...), V/V, volumetric strain (after Martin 1997) and superimposed typical cumulative AE re- sponse (after Eberhardt 1998). Figure 2. A typical stress-strain curve from a discrete element simulation involving a bonded particle model under triaxial loading with a 3 of 20 MPa. Accumulation of new cracks...

... element model was ca- librated against the actual field data from the first test sites to predict and compare to the second test site field data. The field data from the second test site will also be used for refining the same computer model for future 85 room mine design. After achieving good ground...

...1 INTRODUCTION The design of mining slopes relies strongly on eco- nomical considerations; this is the fundamental dif- ference between civil and mining engineering slope design. Open pit mine designs generally start with the resource model, and mine optimization software tools are used...

... prediction method for estimating pillar stability and will show how numerical modeling can play a significant role in day-to-day mining operations. Since 1986, Golder Associates has been successfully using Displacement Discontinuity models to predict pillar stability for the Doe Run Company at their SEMO...

... is to construct numerical models in order to simulate shotcrete performance. The numerical models that are discussed in this paper were initially developed to model shotcrete test specimens prepared under the ASTM C-1550 test procedure. This ASTM test procedure utilizes a 75 mm thick by 800 mm diameter disk...

.... Thus HM coupling analysis gives more realistic results than H analysis. One of the methods for fluid flow analysis through rock masses is the numerical method. Nu- merical modeling of fluid flow, contaminant trans- port and geochemical reactions in fractured rock has attracted the attention of many...

... 1 HISTORY OF MODELING OF ROCK DRILLABILITY During the early part of the twentieth century, the drilling community did not account for the streng- thening effect of downhole pressure on rock. Kühne (1952) pointed out the effect of pressure and sug- gested that rock may be treated as a Mohr-Coulomb...

...1 INTRODUCTION The use of discrete particle modeling as a practical tool in rock mechanics analysis is becoming more and more realistic due to improvements in computer technology and availability of 3D pore structure cha- racterization. The work presented here is part of the development...
