Assessment of Blasting-Induced Ground Vibration in an Open-Pit Mine under Different Rock Properties

Table 1

Mechanical parameters of rock masses.

Rock type	UCS (MPa)	TS (MPa)	(g/cm^3)	(GPa)		(m/s)	(m/s)
Dolomite	95.73	16.48	3.53	87.62	2.1	5247	2471
Shale	58.21	5.84	2.69	55.85	0.9	3813	2895

Note. UCS: uniaxial compression strength; TS: tensile strength; : dry density; : Young’s modulus; : wave velocity of rock; : wave velocity of rock mass; : number of joints per 10 m.
