MEASUREMENT OF CRUSHING STRENGTH OF COAL

2011-5-9 crushing strength of coal agglomerates and agglomerates diameters show that coal diameters have effect on its compressive (crushing) strength. As the coal agglomerate diameter increases, the coal strength decreases which implies that crushing strength is dependent on the agglomerates diameter and crushing strength is indirectly proportional to

2019-3-1 The results show that one of the traditional statistical models that receives little attention is more suitable than the others to describe the size effect on particle crushing strength. The intact coal strength, i.e., the strength when particle size d → 0, is in the range 10–88.79 MPa, and the coal mass strength, i.e., the strength when d → ∞, is in the range 0.92–8.03 MPa. The tensile strength of the matrix is 0.7 times the intact coal strength.
