Maximizing the overall effectiveness of teleoperated underground loading and haulage equipment

CIM Vancouver 2010
Abstract Teleoperation and automation of underground loading and haulage equipment are undeniably beneficial with regard to working conditions and safety of miners. However, in order to justify considerable cost associated with their implementation, mine operators would like to see also an increase of equipment’s productivity. Some past implementation attempts have indicated that the success in this respect is far from guaranteed. With regard to the above, this paper discusses overall equipment effectiveness (OEE) and its components (availability, utilization and production rate) for the case of autonomous loading and haulage equipment. It presents and analyzes importance and criticality of individual factors affecting them. Particular emphasis is put on the problems and issues that are not present in conventional man-operated loading and haulage systems. The paper indicates the ways to eliminate or, at least, mitigate their negative impact. It also stresses the need for more in-depth analyses of the above mentioned factors than those reported in the technical literature up to now. Results and conclusions of these analyses would be very useful at the stage of feasibility studies of the projects involving autonomous underground loading and haulage equipment. The paper concludes with some practical recommendations and suggestions concerning future research in this field.
