A 23-year-old man died on the spot after a heap of Copper concentrates collapsed on him at Kansanshi Mine in Solwezi.
The incident happened as the miners were loading the commodity on a front hand loader using shovels on Thursday night around 21 hours.
One other miner escaped unhurt.
Both Northwestern Province Commanding Officer, Fabian Katiba, and a brother to the deceased, James Nyumbula, confirmed the death of David Nyumbula, of Mushitala compound in Solwezi.
Mr Katiba said Police have launched investigations into the cause of the accident.
He said the body of the deceased is in Solwezi General Hospital mortuary awaiting postmodern and burial on Monday next week.
This is the second death recorded at Kansanshi mine, within 12 months.
Last year, a spotter was crushed by a truck in the mining area.
