MAIN STAGES OF BUILDING A CO MPUTER MODEL OF ROCK MASS
The current capabilities of automated information systems of modelling of rock masses and mineral deposits are examined. A comparative analysis of the possibilities of some of them, which are formed on the basis of the findings on the use, is made. the processes of finite-element covering the geological model and direct selection of the type and kind of finite element are also discussed. The complexity and especially the construction of models of the rock mass in areas with large defects and faults are considered. The advantages and disadvantages of using the finite element in the form of octahedral and triangular prisms are discussed and a common sequence of actions to build a large-scale threedimensional finite element model of the rock mass is formed.
