Photoelectrocatalytic Treatment of Waste Originated from Gold Mines

Silicosis on the Witwatersrand Gold Mines.

Silicosis is an incurable non-infectious occupational disease. It is one of the pneumoconioses, a generic group of long diseases associated with dusty occupations. Silicosis is caused by continuous inhalation of microscopic particles of free silica (quartz) dust measuring from one to three microns in diameter (a micron is equivalent to 0,0001 centimetres). If these particles penetrate to the de...

Eligibility for Isoniazid Preventive Therapy in South African Gold Mines

SETTING The "Thibela TB" cluster randomised trial of community-wide isoniazid preventive therapy (IPT) to reduce tuberculosis incidence in the South African gold mines. OBJECTIVES To determine the proportion of participants eligible for IPT and the reasons and risk factors for ineligibility, to inform the scale-up of IPT. DESIGN Cross-sectional survey of participants in intervention cluster...

Occupational Respiratory Diseases of Miners from Two Gold Mines in Ghana

Objective: This study investigated respiratory disorders among gold miners in Ghana, a sub-Saharan African country. Material and Methods: A cross-sectional exploratory design that employed quantitative methods was conducted among 1001 male workers from the Obuasi and Tarkwa mines from December 2015 to April 2016. A total of 1001 workers, consisting of 505 and 496 underground and surface miners,...

Broadband Records of Earthquakes in Deep Gold Mines and a Comparison with Results from SAFOD, California

For one week during September 2007, we deployed a temporary network of field recorders and accelerometers at four sites within two deep, seismically active mines. The ground-motion data, recorded at 200 samples/sec, are well suited to determining source and ground-motion parameters for the mining-induced earthquakes within and adjacent to our network. Four earthquakes with magnitudes close to 2...
