Collapse of the Fines Ore Storage Building at the Nkana Division of Zambia Consolidated Copper mines

During February 1982 a steel arch structure belonging to the Nkana Division of the Zambia Consolidated Copper Mines Ltd. collapsed, fortunately without injury to anyone. The building had stood for 46 years, and it was used to store crushed ore before the ore was conveyed to the copper concentrator for the next stage in processing. In his capacity as Chief Engineer Civil, of the then Technical Servi.ces Unit, the author investigated the cause of the collapse. R.G. Allaway
