采用 TYJ-500 kN 电液伺服岩石剪切流变试验机，从煤散体物理参数测试与直剪试验两方面，研究了不同剪切速率下煤散体的抗剪强度，指出随着剪切速率的增加，煤散体的抗剪强度呈先增大、后减小趋势。%Applying TYJ-500 kN electric hydraulic serving rock shearing flow testing machine,starting from two aspects of coal dispersion physi-cal parameters test and direct shear test,the paper studies the coal dispersion shear strength with different shear rate,and finally points out that:the coal dispersion shear strength will firstly increase and then reduce with the shear rate increasing.
