"VIRTUAL REALITY IN MINE TRAINING"
L. Mallett, National lnstitute for Occupational Safety and Health, Pittsburgh, PA
R. Unger, National lnstitute for Occupational Safety and Health, Pittsburgh, PA
A representative from each participating organization gave a brief overview of their VR projects. Some highlights of the presentations are provided below not to summarize them, but to give an idea of the breadth of work being done around the world in this area of research and development.
CSlRO - VR in Mlne Automation, presented by Con Caris 澳大利亚科学及工业研究院
CSlRO has developed techniques for integrating complex, geospatial scientific data sets into web-accessible 3D models. This allowed previously dispersed data to be accessed throughout an organization so personnel can evaluate complex spatial data in a common environment and provided an interactive training tool for mine operations. It is now finding ways to provide data in real-time from an underground longwall system (Figure 1). One result will be a better description of the status of the mining process as it proceeds. Another is a training system that enhances the operator's understanding of his or her role in the longwall mining process.
One of their simulations is used to teach drill rig operation (Figure 2). They also use VR to provide a holistic approach to learning in their engineering program. Assignment data, such as spreadsheets, photographs, schematics and textual descriptions, which were previously distributed via printed course materials, are now presented in the realistic context of a VR mine.
Western Australia Department of Industry and Resources – The Use of Digital Photographs & Photogrammetry to Produce a Vlrtual Environment for the Use of Accident and Incident Investigation as well as Training Scenarios, presented by Ken Fowle
The WA Dept. of Industly and Resources uses 3D interactive virtual environments and digital photogrammetry to create tools for accident and incident investigations. Better understanding and presentation of past events can be used to prevent future ones. It is also supporting mining applications ranging from the analysis of rock mass structure to the monitoring of the mine environment using 3D imaging tools and 30 data analysis techniques.
Deutsche Montan Technologie GmbH and Deutsche Steinkohle -Knowledge-Based Maintenance and Trainlng Systems for the Mining Industry, presented by Christian Medrow
Researchers at DMT and Deutsche Steinkohle believe virtual reality will assist the mining industry as it faces increasingly complex operating processes, rising equipment costs, increasing mechanization, and pressures to increase productivity while maintaining high safety standards. They have developed VR longwall shield supports, a plough guide, and a tailgate drive for training purposes (Figure 3). They also see great opportunity for miners to use new technologies while doing maintenance tasks. They have created a program for a hand-held device to store information miners can use on the job (Figure 4). For example, maintenance workers can access machine information while doing their jobs and training for them.

AlTEMlN - Virtual Reality as a Tralning Tool for Mine Machlne Operators, presented by Carlos Catailna
University of
Dr. Schofield has conducted research on the effects that viewing and interacting with VR environments have on the viewer. This issue will become increasingly important as realism of computer-generated accident recreations improves. Allowing a trainee to experience a "real" accident might be a valuable teaching tool (Figure 7). Reconstructions can be used not only in training, but also in prevention as the virtual accident is reviewed and the virtual environment modified to assess potential prevention strategies.

Virginia Polytechnic Institute - VE Initiatives at Virginia Tech: lmmersive Virtual Environments for Mlnlng and Engineering Applications, presented by Doug Bowman
Investigators at VPI are focusing on ways to reduce injuries and fatalities resulting from powered-haulage equipment in metal and nonmetal mines. They have begun work on training applications for conveyor belts and haul trucks. Both cover hazard recognition and potential consequences of missing hazards during inspections and operation.
