Historically, mining has been an enormous contributor to the development and sustainability of several societies. The industry despite being a source of wealth is not without risks and challenges, including environmental and operational hazards. These pose a huge challenge to the safety and...

The mining industry is one of the key economic drivers in Zambia and has tremendously grown since its genesis in the early 1900’s. Zambia is one of the largest copper producers in Africa and the world and this translates to thousands of tonnes of mining waste accumulated over the years. Mine...

This study sought to investigate the cause of the frequent drill rig breakdown at Lubambe Copper Mines (LCM) in Zambia. A multimethod approach was adopted. The result of the study showed that human factors, environmental factors, maintenance factors and Supply Chain related factors were the cause...

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...

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...

Among the various risks on the road, driving second hand tyres is a contributor to accidents. Roadway is a dominant mode of transportation in Zambia and records the highest number of deaths and injuries caused by accidents in the country. An analysis of the traffic accidents recorded over a...

Rock slope stability is a very important research area for many geo-engineers concerned with civil or mining works. Slope stability of pits, roads, tailings dams and other embankments is very cardinal as it directly impacts on the working or utilisation of these facilities. The Nchanga Open Pit...

This study was undertaken to develop an optimum production plan for an underground mine using Renco Mine, an underground gold Mine in Zimbabwe,as a case study.A detailed structural analysis of the orebody's grade distribution has been done to establish technical parameters for production...

In hard rock mining, drilling and blasting still remain the main method of fragmenting rock. In mining methods involving the use of long holes, extra costs are incurred as a result of consequences associated with hole deviations.The consequences include build-ups, hang-ups and poor rock...

The decline is a major excavation in metalliferous mining since it provides the main means of access to the underground and serves as a haulage route for underground trucks. However, conventional mining of the decline to access the ore body poses economic and technical challenges that require...
