Abstract：it is found that when bi-linear cumulative charge column is constrained to charge holes by spacer, the explosion energy of charge presents a linear shaped beam and plays a role of cutting along the fracture surface. High blasting stress wave, high pressure gas expansion and cumulative cutting function together and bring a fracture in to existence on the rock. And all mentioned above, combines cumulative blasting and pre-splitting blasting together, realizes the application of bi-linear cumulative pre-splittingg blasting in the mine. Moreover, it played a role in weakening vibration caused by rock blasting and enhances stability of rock slope.
