Liberation properties of middling coking coal under shear

Sep 01, 2017 Abstract. The relationship between shear force and selective liberation of middling coking coal was investigated by crushing the coal at different shear angles (15 , 30 , 45 , 60 , and 75 ). Subsequent analysis of the middling coking coal revealed that as the ash content of coal increased, the shear strength and cohesion increased, while ...
