The study is part of a research project entitled Strength and Consolidation Characteristics of Coal Refuse for Design and Construction of Disposal Facilities supported by the Office of Surface Mining, Department of Interior. Information presented in the report will be used for the design and construction of disposal facilities. Fine coal refuse, which is the waste product washing through a no. 28 (0.589 mm) sieve, can be disposed in two different forms: solid or liquid. To be disposed as a solid, the moisture content of fine refuse must be reduced. The investigation on the undrained shear strength of partially saturated fine refuse proceeded in the same manner as that of the combined refuse, and similar equations and charts were developed. These equations and charts can also be used to estimate the undrained shear strength of consolidated fine refuse when disposed as a slurry. To be disposed as a slurry, the fine refuse must be pumped into a lagoon or behind a dam and let settle.
