Coal tailings dams and waste piles are the garbage of coal production, but their volumes make them major structures. Without adequate engineering design, they are like bombs waiting to be exploded. Mine waste embankments may fail for several reasons: weak foundations, very steep slopes or excessive heights, high piezometric water levels, overtopping of the pond water, and piping of fine materials by seepage. Essentially the same engineering principles that are used in earth dam design also apply to mine waste embankments. Yet the adaptation of these techniques is often severely hampered and even modified by the peculiar constraints of waste piles, such as economics, material properties, site availability and lack of instrumentation. The construction techniques employed also necessitate that the water flowlines and potential boundaries be treated differently.
