 Upon mine closure and mine reclamation a steel headframe is easier to demolish and may have value as scrap metal.A recently erected steel headgear in the Zambian copper belt town of Chililabombwe at the Konkola number 4 shaft has a total height of 81 metres to the top of the maintenance crane rail, with the centre-line of the head sheaves at 71 metres above the collar, making it the highest steel headgear in Africa.Concrete headframes require less maintenance and are less susceptible to corrosion than steel headframes.
