The planned stages of developing a quarry are viewed in 3D. By importing data representing the surrounding areas and local community the visual impact of the project can be assessed, including nominating the camera position and target to assess the visual impact from a specific point.
Photographic images may be accurately draped over a DTM of the quarry surface. The user is then able to digitise directly onto the surface. This is a great tool for mapping physical boundaries such as geology outcrops which can then be extended into 3D for subsurface interpretation.
Quarry design is made easy in Quarry. The design surface is built step by step from the bottom up or top down. Multiple ramps may be included, and the design may be extended to match a seam or land surface at any time. The height of benches and width of berms is flexible throughout the design process.
A variety of data may be brought together in graphics in order to study the 3D relationships between geology, quarry design or survey data, faults and grade models. The block modelling module is optional.
A different scenario is shown where geology sections and slicing planes allow compex 3D data to be viewed and modelled effectively.
Existing data such as DXF information is imported directly into Quarry. Here we see both surface data and a geology surface generated from underground contours. Accurate volumes between such surfaces are available using several reliable techniques.
Quarry is the world leader in storing and managing drillhole information. The user is able to use his preferred database product or generate the database directly in Microsoft Access or Paradox format directly with Quarry. Sections may then be extracted and viewed with ease, and geology models created in 3D within a friendly graphics and CAD environment.
The creation and sectioning of 3D geology models allows areas and volumes to be established, and may be viewed in graphics while designing the quarry to ensure the most efficient and reliable quarry design.
Once geology polygons are generated from drillhole sections and surface maps, 3D models may be generated. These models may then be re-sectioned in any orientation for presentation in maps and plans together with other relevant data.
Here the original geology polygons are shown together with the solid model. There are several algorithms, including an automatic stitching option, which aid the user to ensure that realistic models are achieved. The models are then validated to ensure reliability when reporting volumes.
Plotting is an essential requirement of most quarrying operations. Quarry is both efficient and flexible in this important area. Plots are fully customisable, and include multiple viewing areas, custom title blocks, colour fill, and editing of detail before sending to the plotter.
The plotting of drillhole data is also very flexible. Multiple grades can be shown with each drillhole, and data such as orebody sections, or faults may be viewed as well. In this example a plan view of the drillholes is shown in strip form at the top of the sheet, with colour fill representing grade contours or surface outcrop.
