The mechanical shearings of SRC and coal were investigated at room temperature up to 5 GPa load pressure by using a self made high pressure apparatus capable of generating simultaneous shear deformation. All shearing curves reached an equilibrium value after rapid increase of shear stress and these values and the subsequent variations were depended upon the coal type. The shear strength of coal was estimated from the corresponding shearing curve and the mechanical behavior of coal at high pressure was analysed from a viewpoint of mineral-matter content. Effect of pressure on the macroscopic shear strength of coal was not so large different from that of rigid polyvinyl chloride resin. The erosion of letdown-valve is discussed.
