    Underground mine automation has the potential to increase safety, productivity and allow the mining of lower-grade resources. In a mining environment with both autonomous robots and humans, it is essential that the robots ...
  • Green, JJ; Hlophe, K; Dickens, J; Teleka, R; Price, M (2011-07)
    Underground mining robotics has not enjoyed the same technology advances as above ground mining. This paper examines sensing technologies that could enable the development of underground autonomous vehicles. Specifically, ...

    Underground mining robotics has not enjoyed the same technology advances as above ground mining. This paper examines sensing technologies that could enable the development of underground autonomous vehicles. Specifically, ...
  • Green, JJ; Coetzee, S (IEEE Xplore, 2012-08)
    The end state of an autonomous system in South Africa’s deep mines is a “fait accompli”. The current unacceptable safety records, and the increasing dangers as the mines get deeper, necessitate the removal of miners from ...
  • Dickens, JS; Van Wyk, MA; Green, JJ (IEEE Africon 2011, 2011-09)
    Mine vehicles are a leading cause of mining fatalities. A reliable anti-collision system is needed to prevent vehicle-personnel collisions. The proposed collision detection system uses the fusion of a three-dimensional ...
  • Green, JJ; Vogt, D (2009-10)
    Mining methods in South African deep level gold and platinum mines have remained relatively unchanged for the past hundred years. A Robot Miner has the potential to mine in a different way. This project is an initiative ...
  • Dickens, JS; Green, JJ (RobMech, 2011-11)
    A pedestrian detection system for underground mine vehicles is being developed that requires the segmentation of people from thermal images in underground mine tunnels. A number of thresholding techniques are outlined and ...
  • Green, JJ (IEEE Xplore, 2012-11)
    The Council for Scientific and Industrial Research (CSIR) in South Africa is currently developing a robot for the inspection of the ceiling (hanging-wall) in an underground gold mine. The robot autonomously navigates the ...
