Abstract

Hundreds of coal refuse impoundments are constructed each year to dispose of coarse and fine coal refuse. As the need for more sites develops, the suitability of available sites decreases. This creates the need for alternative construction practices such as upstream tailings dam construction methods. These methods raise the question of how to analyze the seismic and liquefaction stability of these structures. The use of down hole nuclear density and moisture probes provides a reliable method for assessing the potential stability issues for these types of structures.

Evaluation of Liquefaction Potential of Coal Slurry

St. Louis, Missouri

Hundreds of coal refuse impoundments are constructed each year to dispose of coarse and fine coal refuse. As the need for more sites develops, the suitability of available sites decreases. This creates the need for alternative construction practices such as upstream tailings dam construction methods. These methods raise the question of how to analyze the seismic and liquefaction stability of these structures. The use of down hole nuclear density and moisture probes provides a reliable method for assessing the potential stability issues for these types of structures.
