Abstract: Preparation Plant in the blending process,the need for blending complex coal quality accurately predict.Based Coal Quality,the composition of complex nonlinear relationship between a single coal,according to the Elman neural network model can approximate any nonlinear function features and has the ability to reflect the dynamic characteristics of the system,using the Elman neural network to establish blending coal quality prediction model.The results show that the Coal Quality prediction model can accurately predict the Coal Quality,has a certain reference value and guiding significance in practical work.
