Abstract
Coal is often processed near coal mines to remove some impurities before it is transported to its users. Each year, millions of tons of refuse are generated and need to be stored in the coal producing regions. A typical coal-waste storage facility is a tailings dam which includes an embankment made of coarse refuse and impoundment slurry of fine refuse. Because of the high water content and low shear strength of the fine refuse, coal-waste tailings dams are vulnerable to earthquake induced failure. This article reports on a project to study the seismic response of coal-waste tailings dams using centrifuge modeling. Three tests were conducted on small scale models constructed by the down-stream or up-stream methods. The results of the model tests were used to study the mechanism of response and to compare with available design procedures.
