Project Summary

This project is integrating subsurface stratum geology of Khewra salt mine with BIM (Building Information Model) to create a 3-dimensional model of the mine. A virtual environment of the subsurface mine is created using First Person Perspective (FPP) to give display of the model an interactive interface using a web application.

Building Information Modelling (BIM) was first used by Chuck Eastman and Robert in 1940 to improve the traditional modelling methods in AutoCAD. BIM is a complete procedure of modelling anything. In 1992, "Revit Software" was developed for making BIM integrated models. Now "Autodesk Revit" is available for modelling. BIM refers to the creation of intelligent models that can replicate themselves according to work progress. This process helps in managing a cloud platform along with the model, usually a dynamic database. Furthermore, it provides asset-representation of a model throughout its lifecycle. BIM is not used for buildings only; it can be used for anything that is in the process of building. This technique can help to develop a complete life-cycle details of working of a mine converting Building Information Modelling (BIM) to Mine information Modelling (MIM). A virtual mine can be designed to provide a work framework of a mine. Afterwards, this information can be shared with the mining industry.

Geological Model is used for generating a digital and computerized view of subsurface geology. This geology includes all the layers of Earth's Crust which are based upon geophysical and geological investigations. It has a great application in Mining, Oil and gas industries. It gives a complete model of rock type, mineral layer deposits, reservoir quality and geostatistical information. Such models help GIS (Geoinformatics) Engineers, Civil Engineers and Geologists to visualize all the stratum information just by looking into a detailed Geological Model. In this regard, Borehole Data is of supreme importance. Boreholes are produced by geologists working at a site to analyze the subsurface rock type, thicknesses of certain deposits and depth of a certain lithology. This borehole data can also be generated digitally by using computer software. The primary source for generation of boreholes is seam data. This data helps to create thickness wise boreholes which can further be used for Geological Modelling.

Project Objectives

The following objectives explain the project properly.

• To generate a BIM based 5-Dimensional Model of  Khewra Salt Mine.
• To create a First-Person Perspective (FPP) for virtual visualization of Khewra Salt
• Utility Management

Project Implementation Method

1. Tunnel modellingin revit:The centerline is assigned elevation information as it embodies the plane distributive and space construction characteristics. Every section of the centerline forms the space grid structure. The relevant parameters (such as the start and end points, linear parameters, coordinate system) can be processed using a computer to visualize the “skeleton structure” of the mine working. The sectional shape reflects the characteristics of the sub-elements, such as distribution, shape, dimension, and position. By applying a loft modifier and an appropriate embellish, a 3D geometrical model of mine working is formed. The 3D geometrical model is parameterized, which means it is suitable for computer processing, and the information model synchronization can rapidly respond even if the centerline changes. The relevant drawings and documents can also be generated from the adjusted geometrical model, which avoids errors such as drawing mismatches that may occur in manual modification.

2. Geological modelling in Civil 3D: Geotechnical modeller extension was used to create geological model. The borehole data was extracted from cross sectional maps of Khewra mine and that data was used to create 3d model.

3. Asset management: Web application based on Power BI was made that connected fbx and ifc model.

4. First person perspective: Model was made in Unity3D and the first person perspective was integrated.

Benefits of the Project

A reasonable mine information model is helpful in realizing the innovation and sustainable development of the production and management technology of mining enterprises.

This application would be useful for mine engineers and managers to visualize the working of mine effectively.

Tourists can also visualize the mine using first person perspective without actually going into the mine.

Technical Details of Final Deliverable

The final product would be a web application that would show the 3D geological and tunnel model and the mine managers would be able to keep track of the the assets in the mine.
