GMSG: open mining format to improve 3D interoperability

Global Mining Standards and Guideline Group (GMSG) have released a report stating that a survey of more than 18 3D software applications has demonstrated that users experience significant difficulties and delays working with the software, collaborating with peers and learning multiple proprietary programmes. A solution to these difficulties is an open mining format (OMF) that would encompass a set of guidelines and recommended steps. 

Currently, mining companies use multiple applications to manage and manipulate their 3D models. Many job functions including surveyors, geologists, mine engineers, and managers, need to be able to move from one 3D data application to another with consistency and relative ease in order to manipulate 3D projects while collaborating with clients and colleagues. This is where issues arise, as many of these applications and software do not allow for easy, clean and accurate movement of 3D information.

“If you’re importing a model from one software to another and not double checking that the variables are imported correctly, you could totally screw up pit operations,” said one report interviewee.   

Having multiple applications creates common technical challenges and common process challenges that can result in significant setbacks. Some technical challenges are more common than others. These issues revolve around scripts, ASCII, flat files, name conventions, rotation of 3D images, validity, colour models, managing coordinate systems and file size, while the significant process challenges are the time loss, reverse engineering, restricted use of available technology, additional costs, and increased risk. 

The report says an OMF is a better solution to transferring, managing and manipulating 3D information and would improve the compatibility of mining software packages resulting in fewer issues with manipulating 3D information. 

The report is based on interviews of five representatives from the mining industry and two additional interviews with industry stakeholders. Some of the representatives included industry leaders such as Teck, Barrick Gold and Newmont. These interviews involved a discussion of the current state of interoperability in 3D application technology.
