Model Test Study on Cylindrical Blasting Stress Wave Propagation across Jointed Rock Mass with Different Initial Stresses

Table 1

Physicomechanical parameters of prototype used in the model test.

Type	Rc (MPa)	σt (MPa)	E (GPa)	φ (°)	c (MPa)	μ	ρ (kg/m^3)
Prototype	120	12	50	30	30	0.223	2600

R_c, σ_t, E, φ, c, μ, and ρ are the uniaxial compressive strength, tensile strength, elastic modulus, internal friction angle, cohesion, Poisson ratio, and density of the prototype and similar material, respectively.
