Context

Illegal mining in abandoned shafts around Johannesburg continues amid high gold prices, poverty, unemployment and the failure of mining companies to seal disused shafts, according to The Guardian. Police regularly announce arrests, but researchers say illegal miners number in the tens of thousands.

Politicians have pointed to illegal miners as the cause of sinkholes ahead of 4 November local elections, while experts cited by the Guardian attribute them largely to industrial dewatering of dolomitic rock.

Conflicting Reports

  • Johannesburg council member Kenny Kunene attributes sinkholes to illegal miners; Columbia University's Rosalind Morris says formal industrial mining is the biggest cause.
