Nchanga Underground Mine applies a variant of block cave mining to exploit the massive copper ore deposits with generally low ore grades fairly distributed within the orebody. Mining activities date as far back as 1937 when underground production commenced. Traditional block caving mining method...
Download PDF ↓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...
Download PDF ↓The objective of this research was to characterise the rockmass to determine appropriate support system for the decline with the 4.5m height and 4m wide in highly aquifer strata, recharging the water flow of 18, 000 cubic meters per day. As a result production targets reduced due to excessive...
Download PDF ↓In the Chisamba area, some lithologies hitherto mapped as quartzites and dolomitic marbles are quartz mylonites and interbanded calc-silicate, marble and amphibolites, respectively. Both meso-and microstructural fabrics in the Chisamba area indicate that deformation associated with shearing was...
Download PDF ↓An empirical assessment of the peak shear strength of rock discontinuities occuring in the hangingwall rock formations at Nchanga Open Pit is presented in this dissertation. A brief history and geology of the open pit including its structural and geometrical setting are outlined. Some recent...
Download PDF ↓The use of backfill in underground mines has increasingly become an integral part of overall mining operations all over the world. This has largely been driven by the need to increase ore recovery and productivity. The underground mining activities have given rise to creation of large volumes of...
Download PDF ↓The Kaseba-Katota area is part of the Mesoproterozoic Irumide fold belt trending in a northeast - southwest direction and covers part of the Eastern and Central provinces of Zambia. Outcrops in the area include metasediments, which have been subjected to intense deformation resulting in strong...
Download PDF ↓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...

Download PDF ↓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...
