Cost‐effective in‐mine seismic experiments to image platinum deposits and associated geological structures at Maseve platinum mine, South Africa

Silicosis at autopsy in platinum mine workers.

BACKGROUND South Africa is the largest producer of platinum group metals in the world. Platinum is found in the Bushveld Complex in the north-east of the country. This volcanic intrusion contains many other minerals, including crystalline silica. Little is known about the health risks in the platinum mining industry. AIMS To explore the potential for platinum mine workers to develop silicosis...

South African platinum mine employees reduce smoking in 5 years.

BACKGROUND South Africa adopted comprehensive tobacco control policies in the 1990s. Smoking has since declined in the general population, but there is little information on the effect of the campaign in labour-intensive industries, especially the mining industry where workers are exposed to dust, which may interact with tobacco smoke to cause respiratory disease. OBJECTIVES To determine the ...

Investigating the health-related quality of life (HRQOL) of surface and underground mine workers at a South African platinum mine.

To the Editor: Health-related quality of life (HRQOL) in the workplace is receiving increasing attention, probably because of findings that better functioning, general health and wellbeing and lower levels of pain are associated with higher productivity, dependability and creativity, overall higher work quality and lower absenteeism.1-2 However, no research has been conducted on HRQOL in the So...

The seismic velocity distribution in the vicinity of a mine tunnel at Thabazimbi, South Africa

Analysis of the refracted arrivals on a seismic reflection profile recorded along the wall of a tunnel at an iron mine near Thabazimbi, South Africa, shows variations in P-wave velocity in dolomite away from the de-stressed zone that vary between 4.4 and 7.2 kmrs, though values greater than 5.8 kmrs predominate along most of the profile. The seismic velocities at the tunnel wall, however, vary ...
