South African authorities say 31 illegal miners killed in explosion in May, only now coming to light

JOHANNESBURG —  At least 31 people were believed to have died in a gas explosion in a disused mine shaft in South Africa that happened last month but was only now coming to light, authorities said Friday.

The suspected illegal miners were believed to have been killed on May 18 and most of their bodies were still underground, South Africa’s Department of Mineral Resources and Energy said.

Authorities were being prevented from sending a search team into the mine to retrieve bodies because there were still dangerously high levels of methane gas in the shaft, the department said in a statement.

It said it was considering various options to “speedily deal” with what was “a unique and strange situation.”

Illegal prospecting is rife in South Africa’s old gold-mining areas, where miners go into closed and often dangerous mine shafts to dig for deposits.

The government department said it had received information that three bodies had been recovered after they were brought to the surface by other illegal miners. Another 16 suspected illegal miners who were also in the shaft have handed themselves over to authorities, police said.
