Evaluation of structural properties of coal seams

Conference ·
OSTI ID:5833439
A correlation between the rank, ash content and coal seam discontinuities and coal strength/stiffness is discussed. Rebound hammers were used to evaluate the strength properties of two coal seams. The coefficient of variability of the rebound tests are compared with those of laboratory compressive strength tests by other investigators. 8 references, 6 figures, 6 tables.
