History of endeavours to mitigate the rockburst risk in South African mines

Author: Durrheim, RJ ; Riemer, KL Date: Apr 2012 Gold was discovered near present-day Johannesburg in 1886. Mining-induced seismicity was first encountered in the early 1900s when extensive stopes reached depths of several hundred meters. The State appointed committees in 1908, 1915, 1924, ... Read more
Influence of Mn on the tensile properties of SSM-HPDC Al-Cu-Mg-Ag alloy A201

Author: Müller, H ; Masuku, EP ; Curle, UA ; Pistorius, PC ; Knutsen, RD ; Govender, G Date: Mar 2011 A201 aluminium alloy is a high strength casting alloy with a nominal composition of Al-4.6Cu-0.3Mg-0.6Ag. It is strengthened by the O(Al2Cu) phase and the ’(Al2Cu) phase during heat treatment. Further strengthening of this alloy system can ... Read more
Introduction to the geophysical methods applicable to coal

Author: Fourie, S ; Van Schoor, Michael ; Vogt, D ; van der Walt, J ; Jikelo, A ; Campbell, G ; Du Plessis, A Date: Jan 2015 This chapter introduces a range of geophysical methods that may be applicable to coal mining and exploration problems.

Macro and micro management of hearing conservation in the South African mining

Author: Edwards, AL ; Franz, RM Date: Mar 2009 Noise-induced hearing loss (NIHL) can be prevented, but only by incorporating more proactive and innovative measures into our NIHL-prevention programmes. At present, direct and indirect costs to the mining industry resulting from occupational ... Read more
The noise-induced hearing loss milestones: past and future

Author: Edwards, AL ; Kritzinger, D Date: Oct 2012 At the 2003 Mine Health and Safety Summit, the milestones for elimination of Noise-induced Hearing Loss (NIHL) in the mining industry were agreed on. The first milestone, December 2008, has passed and the next one in 2013 is looming. The study ... Read more
The physical properties of coal

Author: Van Schoor, Michael ; Mare, L Date: Jan 2015 This chapter explains why geophysicists usually want to know as much as possible about the physical properties of the different lithological units in an area before embarking on a geophysical survey. We also highlight some of the common ... Read more
A preliminary investigation of workplace stress in platinum miners using subjective and objective measures

Author: Edwards, A Date: Apr 2011 Workplace stress in the mining environment will affect health and safety outcomes in the workforce that could result in accidents and injuries, as well as poorer worker health. Increased knowledge of the specific characteristics and incidence ... Read more
