300kN Rocks Tensile,Compression and Flexure Testing Machine DETAIL 1. Application → uniaxial compressive strength test of coal and rock, measuring uniaxial compressive strength and softening coefficient of coal and rock. → uniaxial compression deformation test of coal and rock, measuring elastic modulus, secant modulus, deformation modulus and poisson's ratio of coal and rock. → tensile strength test of coal and rock, fracture strength test of coal and rock, load strength test of coal and rock. → shear strength test of coal and rock, shear force test of variable Angle plate, double-sided direct shear test and single-side direct shear test. → rock frost resistance test, measure rock frost resistance coefficient. → compressive strength test, tensile strength test, flexural strength test, shear strength test and point load strength test of highway engineering rock, hydropower engineering rock and engineering rock mass. - coal and rock test load of 300 kN / 500kN / 1000kN / 2000kN. → loading rate of coal and rock is 0.2mpa /s ~ 1.0mpa /s. → the loading speed recommended by the international association of rock mechanics is 0.1mm/min for axial displacement and 0.5-1.0mpa /s for axial load. 2.
