Johannesburg succumbs to sci-fi sinkholes

Written by Sunday, 28 September 2014 06:21

The ground shudders and heaves, then slowly rips apart, pulling whatever is nearby — houses, trees, cars, factories — into a newly-formed, gaping hole.

It sounds like a scene from a science fiction film, but over the last several decades, this scenario has played out thousands of times — entirely unscripted — near South Africa’s largest city.

The city's landmark Top Star Drive-in site is a shadow of its former self, after the mine dump it perched atop was levelled and re-mined for gold.

Fears that a facility to treat acid mine drainage could contaminate plants, animals and people. Government is forging ahead with a R1-billion project for the treatment of acid mine drainage in Ekurhuleni – despite a fierce backlash by residents and environmental experts over the millions of cubic metres of toxic, and possibly radioactive, sludge the project will churn out.

The 19th century gold rush that built Johannesburg left many abandoned mines in the city that still lure hundreds of people every day who enter them illegally searching for what little gold that remains.

THE Gauteng agriculture and rural development department launched a five-year plan this week, to treat the problem of acid mine drainage (AMD) in the province.
In the past few years people living around Johannesburg have become aware, thanks to environmental activists and visible evidence, that highly tainted water from old gold mines, dubbed AMD, is rising to surface and polluting water sources.

Kagiso uprising

Written by Friday, 18 April 2014 20:59

In this four part series we begin with the protest action in Kagiso early this year. The residents of Kagiso on Johannesburg's West Rand are calling for the complete shut down of Mintails Mogale Gold. This mining operation began unrestrained blasting only 100m's away from their homes late in 2013. People describe an earthquake type effect which cracked their walls and foundations. The community then mobilised to have the mine shut down stating in their list of grievances various laws that had been contravened by the Department of Mineral Resources (DMR) Mogale City and the mining company.

"..in the light of the continuing pollution of one of our country's major river systems and one of our countries largest aquifers, and given the inadequacy of the current treatment plant, it does notmake any sense that several new opencast mine pits could have been authorised right on top of the recharge zone of the Western Basin Mine Void".

Expert opinion on situation in West Rand

Mintails continue to contribute to the recharge (and subsequent decant from) of the Western Basin Mine Void water (by increasing the number of opencast areas through which recharge occurs), which [FSE] rightly say flow at about 20-30 Ml/day form the 17 and 18 Winze shaft areas. However, currently it is probably flowing at double that rate, due to the huge recharge surface area of the new opencast mine pits.

TACKLING the lethal and unsightly legacy of abandoned gold mines around Krugersdorp is not a task for the faint-hearted. But Australian-listed Mintails believes it can play a major role, at the same time as making money for its shareholders.
It is going to cost a lot of money and require some controversial decision-making to address the complex social and environmental problems on the West Rand that reflect illegal mining, communities encroaching on toxic mine tailings, and poisoned water.
