On-lien forecast of raw coal washability curves

摘要

To specific coal preparation plat,the ash content of raw coal is related to its density.The density,in turn,is related to elementary ash content.Based on these relations an on-line forecast system of raw coal washability curves was develoed.It uses Windows with C++.The system can define the washability curves automatically and in real-time.The experiments demonstrate that for cumulative yield,forecast error is less than 0.4 and for cumulative ash,forecast error is less than 0.7.
