Sommaire: The file is a zipped PDF document.The combination of a predictive reliability assessment model and discrete-event simulation can be an effective methodology to study the impact of equipment failures on the capacity of production systems in mines. In this study, a predictive reliability assessment model using genetic algorithms is combined with a discrete-event simulation model to analyze mine equipment systems.Discrete-event simulation studies the evolution of a system as variables change...

Sommaire: The file is a zipped PDF document.Thirty per cent of the electrical energy in Turkey is provided by coal-fired thermoelectric power plants. Five per cent of the demand is met by the Soma power plant’s six 165 MW generators. The plant is fed by lignite from open pit and underground mines in the Soma region that are operated by the government. With a nationalized mining policy in place, recently no investment has been made at these mines, as mining activity is generally considered by the...

Sommaire: The file is a zipped PDF document.Experience shows that energy management is successful when the energy is managed like a resource, i.e. continuously, systematically, and in an organized manner, not like an expense (e.g. worrying about and paying the bills once a month). This requires the development and implementation of an energy management program (EMP).Following is a summary of guidelines for setting up a successful EMP, plant- or corporation-wide. The main driving forces of a successful...

Sommaire: The file is a zipped PDF document.No person can properly work without sufficient lighting and this is especially so in mines where conditions are difficult. Artificial lighting is very important for the night shift to provide a safe and efficient working environment. Haul roads within the pit are one of the critical areas in surface mines where lighting installations are not permanent due to regular advancement of the working face. The illumination design should fulfil the minimum lighting...
