The role of GIS Modelling and Infrared Technology to Detect the Missing Miners Trapped Underground

Following the collapse of the Crown Pillar at Lily Mine on the 5th of February 2016, there was a national outcry to find the unfortunate miners who were trapped in a surface container lamp room that disappeared in the sinkhole that formed during the surface collapse.  A two-way strategy was suggested going forward to find the container. The first approach, which is the subject of this paper, is to test temporal 3D modelling software technology, and second, to use scientific measurement and testing technologies (This investigation appears in a separate article by Hussain and Cawood (2016)). The overall methodology used was to first, request academia and research entities to supply the Wits Mining Institute (WMI) with ideas, which ideas list was compiled as responses came in.  These were scrutinized and literature gathered for a conceptual study on which is likely to work.  The major results of this software screening and preliminary testing exercise are discussed in this article. The findings are that software modelling is likely to locate the present position of the container, but accurate data and a combination of different advanced software packages will be required at tremendous cost.

Curriculum Vitae

Mr. Hamid Ashraf holds a Bachelor of Science Degree in Civil Engineering and a Master Degree in Geographic Information Systems (GIS) from National University of Science and Technology (NUST), Pakistan. As a civil engineer, he has vast experience of construction of highways and buildings in various parts of Pakistan and Liberia. He remained on Civil Engineering and GIS faculty of NUST in the teaching capacity. He is currently a Ph.D. scholar at University of the Witwatersrand, Johannesburg and pursuing his Ph.D. in Mineral Resource Management.

His research interests include geospatial hazard potential assessment using remote sensing and GIS technologies. He has worked on the avalanche risk assessment for parts of Himalayas and Karakorum Ranges (Gyong sector Siachen). Currently he is part of the digital mine research group at University of the Witwatersrand and is working on the geospatial subsidence modelling for the Sterkfontein Caves.
