Abstract:Using the equivalent wave impedance method, the numerical analyses were given about uncoupling coefficient’s effects on transfer course of explosive pressure and energy on hole wall in water coupling blasting. The result was verified by the experiments of blasting fragmentation and fracture law on water coupling blasting at different coupling coefficients. This result is valuable to the project design on water coupling blasting under different conditions.
Key words: water coupling blasting equivalent wave impedance method match of explosive and rock fragmentation experiment fracture law experiment
