The creep characteristics of coal and rock under confining pressure in Songzao, P.R. China were studied. The experimental data were analyzed and discussed in detail. The characteristics of creep could be described by the generalized KB model after the experimental data were fitted. The parameters of the model were obtained. The results show that when the creep load was σ≥σs, the curve of coal and rock under confining pressure displayed three typical phases. In the first and second phases, the fitted curve was consistent with the test curve. Thus, the generalized KB model can describe the whole process of coal creep under confining pressure.
