  • Johnson, RA; Hagan, TO; Squelch, AP; Jaku, E (2000-03)
    Assessments of accident records indicate the need for improved understanding and competence among underground production and service personnel with regard to strata control, and the associated risks, in gold and platinum ...
  • Hagan, TO; Milev, A; Spottiswoode, SM; Vakalisa, B; Reddy, N (CSIR, 1998-12)
    The objective of this investigation is to improve worker safety through a better understanding of mine excavation response to rockbursts. The improved understanding should lead to improved mine layout and support design. ...

  • Brink, AVZ; Hagan, TO (2002-03)
    The objective of the project was to develop a software tool for the assessment of rock engineering (RE) risk based on the concept proposed in GAP 608 and to evaluate the software with real mine data from a deep level gold ...

    The primary output of this report was the determination of geotechnical areas across the gold and platinum mines to form the basis for future understanding of the rock mass behaviour around reefs where the hanging wall and ...
  • Brink, AVZ; Hagan, TO; Spottiswoode, SM; Malan, DF; Glazer, SN; Lasocki, S (2000-03)
    The development of techniques to quantify the potential for rockmass instability that may result in rockbursts, has been a priority for researchers in the South African gold mining industry for some decades. These techniques ...
