Automated tools to be used for ascertaining structural condition in South African hard rock mines

Author: Teleka, Ruth ; Green, J ; Brink, S ; Sheer, J Date: Nov 2011 The use of automation in deep level hard rock mines has over the years been overshadowed by mechanized mining. However, more and more readily, the industry is starting to recognize the validity of considering automation as an option both in ... Read more
CMI and the simulated test stope

Author: Teleka, Ruth ; Green, J ; Dickens, J Date: Sep 2013 The South African mining industry is plagued by accidents ranging from vehicle incidents to roof/rock falls. In the attempt to carry out its mandate of improving the quality of life of South African citizens, the Council for Scientific and ... Read more
Creating three-dimensional thermal maps

Author: Price, M ; Green, J ; Dickens, J Date: Nov 2011 A method for generating 3D maps of mines with thermal imaging texture from a robotic platform is presented. The objective is to use these models to generate risk maps that can be used to assess mine safety. Analysis will take place offline, ... Read more
CSIR Center for Mining Innovation and the simulated test stope: Paper

Author: Teleka, Ruth ; Green, J ; Dickens, J Date: 2013 The South African mining industry is plagued by accidents ranging from vehicle incidents to roof/rock falls. In the attempt to carry out its mandate of improving the quality of life of South African citizens, the Council for Scientific and ... Read more
Integrating two spectral imaging systems in an automated mineralogy application

Author: Harris, D ; Viranna, N ; Hill, G ; Green, J Date: Nov 2009 A system for the automated analysis and sorting of mineral samples has been developed to assist in the concentration of heavy mineral samples in the diamond exploration process. These samples consist of irregularly shaped mineral grains ranging ... Read more
Mine rescue robots requirements: Outcomes from an industry workshop

Author: Green, J Date: Oct 2013 Mine rescue robotics is an area of research and development that has had some attention in the past, but has been bypassed in development by urban search and rescue, where the conditions could arguably be classified as less extreme. The safety ... Read more
Mobile robot competition. Underground mining: A challenging application in mobile robotics

Author: Green, J ; Plumb, S Date: Sep 2011 This paper presents the history, current position and future aspirations of the mobile robot competition. It has been run for a number of years in the past under the guidance of National Instruments as an undergraduate competition for National ... Read more
Point-cloud registration using 3D shape contexts

Author: Price, M ; Green, J ; Dickens, J Date: Nov 2012 The problem of aligning scans from a range sensor is central to 3D mapping for robots. In previous work we demonstrated a light-weight descriptor-based registration method that is suitable for creating maps from range images produced by devices ... Read more
Posture estimation system for underground mine vehicles

Author: Hlophe, K ; Ferreira, G ; Green, J Date: Sep 2010 Platform pose is a key requirement for autonomous systems. The severe natural conditions and complex terrain of underground mines diminish the performance of classical localization systems. This paper proposes a pose (localization and ... Read more
Robotics and automation activities in South Africa

Author: Utete, S ; Green, J ; Liddiard, A ; Burger, Chris R Date: Sep 2013 Second in the series of articles focusing on the state of robotics and automation in the BRICS countries: Brazil, Russia, India, China, and South Africa, this article provides an overview on South Africa written by researchers from the Council ... Read more
Robots in mining

Author: Green, J Date: 01 Sep 2010 This presentation investigated the hypothesis stating that robots can improve mining safety. Mine safety statistics are analysed, and accident features are discussed. The conclusion is reached that robots have a role to play in improving ... Read more
Underground mine navigation using an integrated IMU/TOF system with unscented Kalman filter

Author: Hlophe, K ; Green, J Date: Jul 2011 Platform pose (localization and orientation) information is a key requirement for autonomous mobile systems. The severe natural conditions and complex terrain of underground mines diminish the capability of most pose estimation systems, ... Read more
