Experimental Research into the Ultrasonic P-Wave Velocity of Coal Slime Based Backfill Material

To study the influences of different mix proportions of materials on the ultrasonic p-wave velocity of coal slime based backfill materials, influences of four factors on the p-wave velocity of specimens were investigated by designing orthogonal tests and taking coal slime as the principal raw materi...
