The system of monitoring, control and optimization of coking coal blend fuel will be designed and implemented. The specialised software for simulation of coke quality will be core of the system. Results of analysis of coking coal blends samples downloaded from fuel prepared for coking will be the input data. The programme output will be indications for the blend preparation for the best coke production. The system designing will be realised by Czech company Autel. The implementation will be done by Czech coke producing company.
