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...

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...

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...

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...

All sheet metal forming processes occur after permanent plastic deformation resulting in the material properties changing and therefore it is necessary to determine the extent to which a material can further be deformed for subsequent forming operations. Traditionally, experimental trial and...

This research work was to provide a locally produced electric motor to drive the UNZA pump.The work was carried out by using the UNZA pump parameters and electric motor material from published works on the electric motor design and manufacture and real experience from examining electric motors in...

Recent developments in the design of variable-speed drives have been aimed at the control of a standard squirrel cage induction motor because of its many attractive features including robustness, reliability and low maintenance requirements. This dissertation demonstrates the design of a drive...

This dissertation describes an investigation carried out at Baluba Mine to assess the quality of rock mass and support requirements in haulage drives developed in the -footwall quartzite -Formations. The rock mass o-F the -Footwall Formation is geotechnicallv quantified using the Modi-Fied Basic...

Combustion Efficiency Improvement in a Rotary Furnace using a Post Combustion Chamber. Luwaya Edwin. Department of Mechanical Engineering, University of Zambia.Geometric parameters, of a rotary furnace, necessary for the improvement of combustion efficiency are analysed using Computational Fluid...

This project describes the digital control of a radar that is ideally insensitive to alien disturbance signals. The key factor in this project comprises the design and realisation of a wide range of digital techniques combined into one digital controller consisting of several elements.The project...
