Visualization of mining and geological data based on coal mine KWK “Knurów-Szczygłowice” Ruch “Knurów”

The aim of this work was to create a 3D model of underground workings of fragment coal mine KWK “Knurów-Szczygłowice” Ruch “Knurów” for 550 m and 650 m level. The 3D model has been developed on basis of the digital, two-dimensional mining map (Maciaszek et a l. 2010). Initially, completeness of mining maps has been checked, which allows one to select the south – east area to create the model. The elements were created in 3D space such as: boundaries of the mining area, protective pillars, workings wall, boreholes (Drąg 2011). Creating a model one started from the construction of the simplest form, the axis model. In turn moving to more complex visualization a circular cross-section model has been created. For workings walls the basis for showing them in three-dimensional space was to extrude the surface along the Z axis equal to the thickness of the deposit (Galica 2011). More complex task was modeling protective pillars because of their shape of the area. An important element was to define transparency level each of element from the model. Modeling was performed in Microstation, AutoCAD and with GeoLisp system, which bases on AutoCAD. Afterwards, conclusions for creating three-dimensional mining maps and using programs have been performed (Poniewiera 2008, Krawczyk 2008). The result of the work is an animation showing selected elements of mining map in 3D space (Mertas & Poniewiera 2009).
