In the field of mining engineering, design and planning are complex tasks,
which require the knowledge of various engineering disciplines. GRUBE
(Graphisch-RechnerUnterstiitzter BergwerksEntwurf) is a modular
databased program system, which offers computer aid for all mining
departments using a 3D CAD software as the user interface. Despite the
data quantity and complexity, specific and uniform working conditions
have to be applied to the planning of technical equipment of a pit. With
the application of 3D graphics, complex data stores and their
interrelations become 'palpable' for the user by suitable visualisation.
GRUBE-M forms the mechanical operations module of GRUBE, in
which underground locations displayed as three-dimensional graphic
models are `equipped' interactively. Planning alternatives can be created
and compared quickly in terms of technical calculations and economical
analysis.
