Abstract
On the basis of analysing the structural characteristics and performance of CWM additive derived from coal (hereafter called ADC) in CWM preparation, this paper described the relationship between structure and property of ADC using bonding factor and hydrophobic/hydrophilic factor of CWM additive's structural activity, propounded two kinds of characteristic parameters for determining structural activity of CWM additive, and discussing their effects on the performance of additive in CWM preparation. As a result, the theoretical approach for designing or selecting more effective additives for CWM preparation has been developed.
