Develop a mobile device based tool to identify structural features in geological rock samples
Diamond drilling is used to produce underground rock core samples for geological analysis. These samples contain structural features that geologists use to develop a 3D understanding of ore deposits; where they are and why, and where to look to find more. Engineering geologists also use this information in mine design.
The objective of this challenge is to develop a user friendly tool on a mobile device that can automatically measure the orientation and type of structural features present in the core samples.
Currently, this is a manual process that uses hardware. It can be slow and subject to errors and subjectivity. A mobile based software tool that automates this process could be quickly distributed to mine sites around the world and will create an easy way of collecting accurate data allowing geologists to make real time decisions on site.
Geologists orientate structural features of in-situ rocks by their direction (e.g North, South) and the angle at which they are dipping relative to horizontal. Core samples collected from drilling, are no longer in-situ, so can’t be measured this way.
As part of the drilling process, a core orientation tool is used to provide the in-situ orientation of the core sample in the form of a reference mark, which is then used to mark on the orientation line.
The most common existing method of orienting structural features involves a geologist manually measuring the alpha and beta, which are angles of the feature being measured relative to the orientation line. This data is then entered, along with the structure type, and the alpha and beta data is transformed into true 3D
Potential Areas to consider:
•Is it possible to use existing mobile software and/or hardware for this challenge?
•Custom accessories and fixtures?
•Can you come up with another way to record and view the data in 3D?
6 physical core sample trays will be available at the event. They have been logged and verified using the current methodology. The data from 3 of these trays will be made available for reference, in addition to the physical tools used. The remaining 3 trays can be used to test your prototype.
The data includes alpha and beta angles, and type of features identified. The features may be planar, linear or a combination. All types are described in the data dictionary.
Downhole survey; the azimuth and dip of the drill hole. This data refers to the orientation line marked on the core and is used to transform the alpha and beta to true 3D.
Photos of the drill core are also supplied at various angles.
Submitting your prototype solution:
For this challenge, a second set of samples have been provided to test solutions. The data for these are withheld and will be used to test the accuracy of the solutions. Please ensure you submit the data for this set of samples in your final submission, in the same format of the open dataset for the first set of samples. You will not be judged on this during the weekend, but it will be used by Boart Longyear to identify how successful your prototype is, and to determine potential partners to develop this solution.
