The area of northeastern Zambia, between Chama and Lundazi towns, is underlain by rocks belonging to the Irumide Fold Belt, a Mesoproterozoic orogenic belt whose geology is dominated by biotite gneisses, which often show incipient migmatisation, that belong to the Kampemba Group. Less common...

In practice, cured concrete strength may exhibit strength variation from batch to batch and within batch despite the mixes being of the same proportions and with quality control. On the other hand, structural concrete elements are designed to meet specific characteristic strength. In order to...

The world population continues to grow, with Africa projected to reach 2.4 billion people by the year 2050. This increase in population has resulted in a high demand for goods and services, which has subsequently triggered an increase in demand for mineral resources. Zambia, being a mineral rich...

Despite playing a key role in most economies, building construction contributes significantly to climate change. Buildings consume energy, water, and raw materials, generate waste, and emit potentially hazardous air emissions during the course of their lives. These facts have prompted the...

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...

The university of Zambia’s electricity provides power to operate campus infrastructure such as hostels, lecture rooms, library etc. While telecommunication utilities provide telephone, intranet and internet services. The power and communication utilities are supplied by underground cables....

In any company, the planning and scheduling process is unavoidable. This research investigated its effects in the electrical section of Anvil Mining Congo SA. In this company, the focus of planning and scheduling, particularly on equipment, is on preventative maintenance rather than actions such...

Natural-convection solar tunnel dryers capable of achieving greater drying rates when drying products. The increased temperature decreases the relative humidity of the air, thereby allowing the air to more efficiently dry the product. However, it is necessary to provide an appropriate solar air...

Mining at Kansanshi is currently conducted in two pits namely Main and North West pit. Mining at both pits is conducted by conventional open pit methods involving 18 hydraulic excavators and a mining fleet of haul 86 trucks.There has a been a general concern on the mined material tonnes...

The design and development of ytterbium-doped fibre lasers (YDFLs) operating around 1018nm laser wavelength and pumped around 976nm has advanced in technology since the first ytterbium laser was tested in 1988. The fiber lasers are used in various sectors such as communications, material...
