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...

It is estimated that over three quarters of a million people are killed and tens of millions are injured on the roads in low-income countries each year* and Zambia is no exception. Many, if not most, will come from poor households particularly vulnerable to the risk of road trauma and its...

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...

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...

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...

This study is aimed at making an attempt to address the real problem that faces the Mining Industry today - Mine accidents. Apart from the academic obligations that had to be fulfilled in putting up this work together, the writer's passion to address this problem also emanates from his twelve...

When a modulated beam of 1ight impinges on a solid, elastic waves are produced as a result o-f the surface motion due to thermal expansion. In semiconductors, in addition to this thermal expansion effect, there is also mechanical strain induced in the material due to the photogeneration of excess...

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...

Disputes in the construction industry are often inevitable. Disputes arise from the interpretation and application of any part of ambiguous, unplanned and conflicting contract documents. There are many methods which can be used to resolve disputes. The study in this dissertation examined the...
