Uniaxial compression, uniaxial tension and indirect tension (Brazilian) tests were carried out for coal (anthracite) obtained in a coal mine located about 26 km west of Beijing.<BR>Complete stress-strain curves not only in uniaxial compression test but also in uniaxial tension test were successfully obtained. In post-failure region of uniaxial tension test, the curve showed Class I characteristics accompanied with small amount of residual strength. The peak strength obtained by the uniaxial tension test was far less than the indirect tensile test frequently conducted.<BR>The strain rate was alternatively increased and decreased to obtain the loading-rate dependency. When strain rate was increased, stress increased abruptly by a certain amount depending on the loading-rate dependency of the rock. The experimental results showed that loading-rate dependency of the coal both under the uniaxial compression and tension stress was relatively smaller than the most rocks that had been tested by the authors.
