Abstract

Abstract: Based on the investigation of the leakage causes of the wastewater reservoir in a mine in Jiangxi, the mechanism of acid mine water erosion on the earth-rock dam is analyzed and the anti-seepage technique which adopts a vertical seepage-proof wall built with coal ash-concrete is proposed. The practice has proven that such seepage-proof wall can effectively increase the density and reduce the expansibility of the concrete wall so that the durability of earth-rock dam in an acidic environment can be improved. It can be reference to similar projects.

Key words: Leakage, Acid wastewater, Concrete seepage-proof wall, Anti-seepage measure
