Paper Title:
Corrosion Mechanism of Anti-Seepage Curtain Corroded by Acid Mine Drainage
  Abstract

The acid mine drainage pollution is the worldwide difficult problem induced by mining industry. Based on the investigation and analysis of acid sewage quality component in some mine wastewater reservoir, the interaction and corrosion mechanism are studied between acid mine drainage and anti-seepage curtain, the technological ideas about how to improve and enhance the corrosion resistance of curtain are put forward, providing reference for predicting engineering durability and reinforcement. The corrosion mechanism research shows that the cement frequently take place the decompose and polyreaction because of the double action of solventing out and chemical dissolution during the AMD corroding, it changes the molecular structure inside the curtain and the composition of its framework, so as to lead to the structure loosing, the permeability increasing, and the cement strength reducing, and thus affecting the anti-seepage property and durability of the curtain seriously.
