177 3-D Geological and Laneway Integrated Model of Mine Disaster

To solve the problems in mine disaster rescue arising from separate geological model and laneway model, this paper proposes a multilayer 3-D model which combines the geological model, laneway model and 3-D visualization technique. We first elaborate the techniques needed in 3D model for complex geological body and laneway 3-D model. Then we establish an integrated 3-D model based on the multi-stratum 3-D geological model and 3-D laneway section model. Finally we design an implementation method which takes into consideration topological relationship of node-arc model with stratum lithology and node correlations. From that, we further apply the heuristic searching algorithm in our model and implement intelligent selection of emergency rescue routes. Our result demonstrates that this integrated system of 3-D geological model with laneway model and 3-D visualization technique has great practical value in rescue of mine disaster and in location of the disaster spot.
