Heterogeneity of Rock Corroded by Acid Mine Drainage Based on Fractal Theory

Article Preview

Abstract:

Heterogeneity has been considered as a critical character of the rock structure. Fractal dimension makes it applicable to describe the complexity structure quantitatively. The evolution of rock heterogeneity has been investigated by surface fractal dimension parameter and covering projection method. The fractal behavior of meso-structure of the rock corroded by acid mine drainage was obviously observed. The fractal dimension of the rock structure was chosen to describe the heterogeneity of the rock structure attacked by Acid Mine Drainage. It observed that the fractal dimension of the rock structure increased and the rock heterogeneity became more distinctive during the process of attack.
