the zambian cities series: mufulira part one β history and the night the mine flooded
the city and the mine: mufulira is located approximately 37km north of kitwe and 22km northeast of chingola, close to the DRC border. mufulira mine began operations in 1933, developed by the rhodesian selection trust β the mining house controlling the eastern copperbelt. at its peak in the 1960s and early 1970s, one of the most productive copper mines in africa, producing copper that represented a significant proportion of zambia's national output.
the warning signs: in the two years preceding the disaster, sinkholes and minor mud ingress incidents had occurred around the no. 3 tailings dam β inadequately investigated by mine management.
the night of 25 september 1970: at approximately 2:55 in the morning, large quantities of mud entered the peterson section of the mine between the 434-metre and 580-metre levels. the no. 3 tailings dam β holding approximately 18 million tonnes of slimes β had experienced an underground collapse, creating a sinkhole through which approximately 1 million tonnes of water and tailings rushed into the mine workings below.
there were 1,500 miners on duty that night. the deluge reached them in fifteen minutes or less. 89 miners were killed β trapped underground, drowned or asphyxiated by mud and water that flooded the workings too fast for them to escape. rescue teams came from every copperbelt mine. after three days, rescue operations were called off. 89 men were still missing underground, presumed dead.
it remains the worst mining disaster in zambia's history.
the national impact: the flooding led to a cut of as much as 50% in the nation's copper production. the reduction had a severe impact on zambia's national finances at a moment when the country was only six years old. the aftermath set new standards in mine safety on the copperbelt β a painful form of progress whose cost had been 89 lives.
the zambian cities series continues. πΏπ²π
