Abstract

A simple but quite reliable evaluation method for the stability of coal-water mixtures was proposed. The change of internal structural stress based on the phenomenological thixotropy model was measured by means of a rheometer. The final strength of internal structural stress was well correlated with the experimental results of stability tests. Empirical correlation equations to evaluate both the static and dynamic stabilities of CWM were proposed. These empirical equations enable us to evaluate the stability of CWM by means of a rapid thixotropy test alone.
