oa Civil Engineer in South Africa - Optimum economic allocation of mine water subject to quality constraints



A general co-ordinated optimization planning policy for the distribution of mine service water is described. The optimization is aimed at minimizing the non-linear cost functions which include the procurement, desalination and distribution of the water. Constraining parameters include : yields of the sources, requirements of the demand zones, qualities at the sources and the demands and desalination requirements. Non-linear functions are mathematically handled using the separable programming technique. Computer solutions using linear programming and separable programming are discussed. The technique is applied to a mine on the Witwatersrand Reef, South Africa.
