Mining method selection is one of the most critical activities of Mining engineering with the ultimate goal of maximizing profit, mineral recovery and arrive at a method with the least problems among feasible alternatives. The geology at the Synclinorium is complex with four main lithologies i.e....

Nchanga Underground mine uses a block caving variant to extract the lower ore body of the Nchanga syncline. The deepest part of the ore body, the H Sub-Incline complex, is thin with 4.39m average thickness, 5.27% weighted average grade of Copper and hosts 1,219,314t in-situ. Operational...

Mopani Copper Mines Plc. (MCM) is sinking a vertical rock and man shaft. The rock hoisting winder will handle 2.0 million tonnes of ore per annum. The project will significantly boost the current productivity of Mindola Mine, as it will enable the company to increase ore production from 800...

Backfill is described as waste material that is used to refill the underground voids left during mining for technical or safety purposes. Backfilling has several applications underground and the use of backfill has increasingly become a fundamental part in the entire underground mining activities...

Konkola Copper Mines Plc (KCM) is undergoing full mechanization drive aimed at increasing levels of production from the current 2.4 million tonnes to 7.5 million tonnes per annum. The mechanization of the mines will provide a large potential for reduced costs and improved profits, while at the...

Nchanga Open Pit (NOP) is facing a critical equipment planning decision after undertaking improvement projects at the processing plant namely Elevated Temperature Leaching, Heap Leaching and Cobalt/Copper separation. Elevated Temperature Leaching has resulted in 20% increase in the recovery of...

Temperatures and humidity at Mindola Sub-Vertical (MSV) shaft have been rising with depth as mining of lower lying copper reserves is achieved. This rise in temperature has been catalysed by a number factors notably the increase of diesel equipment, geothermal gradient (increase in depth), auto...

Blasting is the process of fracturing material through the detonation of industrial explosives placed into drilled holes suitably located to a free surface. Every blast hole containing a calculated amount of explosive charge undergoes impulsive loading when detonated and results in the dynamic...

Konkola Mine of Konkola Copper Mines Plc comprises of Number 1 and 3 Shafts located on the northern most part of the Zambian Copperbelt. The mining licence area is characterised by the Kirilabombwe anticline dividing the West and North Limbs striking generally in the northwest to southeast...
