Abstract

Abstract

The quality characteristics of mine drainage with high turbidity were described on the basis of investigating the particle size distribution, the characteristics of suspended particle surface, and the coagulating characteristics in mine drainage, and the influencing factors on the affinity between coagulants and suspended particles in mine drainage treatment were analyzed. The results show that the suspended particles in mine drainage mainly consist of coal and rock grains with small size and negative electric charge which make them hard to naturally subside. As the coal rank goes to higher, the wettability of coal grains and the affinity between coal and coagulants decreases gradually.
