This paper introduces a variant of Artificial Bee Colony algorithm and compares its results with a number of swarm intelligence and population based optimization algorithms. The Artificial Bee Colony (ABC) is an optimization algorithm based on the intelligent food foraging behavior of honey bees. The proposed variant, Artificial Bee Colony Algorithm with Balanced Explorations and Exploitations ...
this study was carried out for the purpose of investigating the issue of tailings dams as a potential source of contamination by trace elements in soils at the sidi bou othmane mine in the marrakech region, morocco. soil samples taken from depths of up to 15 cm and within a radius of 50 m from the tailings dams, were analyzed for cd, cu, pb and zn using atomic absorption spectrometry. average c...
Metal price is one of the most important parameters in the calculation of cut- off grade. The cut- off grade has the main role in determination of mine layout. Mine layout actuates mineable reserve, mine life and economic profitability. Not considering the uncertainty in metal prices can lead to a non-optimal layout. In this paper optimum underground mine layout is determined by expected utilit...
