Establishment and Application of 3D Visualized Model to Mine Main Aquifer

In order set up the effective mine water inrush early warning and the water inrush prevention and control countermeasures, based on No.3 mining block of Danhou Mine as the engineering background and based on the prepared data of the site geological boreholes, the Surpac software was applied to establish a 3D vis ualized model of the mine main aquifer.With the 3D interactive graph functions, the software could be applied to directly display the space location, scale morphology a nd the distribution scope of No.5 seam and No.1 seam as well as the main aquifer in No.3 mining block.With the statistical analysis and calculation, the water isolation t hickness contour drawing between the coal mining faces in No.5 seam and No.1 seam and the nearby aquifers could be obtained including the min water isolation layer scope between the nearby aquifer and each coal mining face.The flow field area and volume was determined.A rational mining sequence was provided.The analysis cou Id be conducted under the complicated hydrogeological conditions and the water inrush could predicted and prevented.
