Because of the danger of blasting to local underground rock-breaking engineering, the construction under complex environment is realized by using prefabricated crack drilling and static crushing technology. In order to predict the crushing effect, based on the cohesion element method, different hole spacing, prefabricated fissure length and surrounding rock are selected to carry out the numerical simulation study of static crushing prefabricated fissure borehole, the prediction models of fracture pressure and initiation pressure are established.
