Interactive system for substantiating and determining the maximum efficiency coal processing, regardless of the technology applied

摘要

For an operative control of a macro system and for establishing scientifically proved likely maximal indicators, an interactive system has been worked out. It enables us to determine the criteria of technical efficiency in accordance with the economic one, imposed by market economy laws. The proposed interactive system gives us the possibility of finding the optimum combination of several raw coal grades of various, dressing, which supply the processing plants in the Jiu Valley, the only coal basin of Romania where coking and semi-coking coal is being mined. The system structure combines 3 programs enabling: selecting the blend of row coal coming from several mines, determining the theoretical weight extractions, function of the terminal product quality and the calculation of probable results by the Fournol method for establishing the maximum achievable weight extraction by taking into account the equipment flaws and the products separation densities.
