摘要
作者运用岩石力学、断裂力学及爆炸力学的基本原理，建立了预裂爆破准静载成缝力学模型，导出了每孔装药量及炮孔间距的计算公式，并通过现场试验证明了模型的合理性．
The authors established a mechanical model for presplitting rock by utilizing fundamental principles of rock mechanics,fracture mechanics and mechanics of explosion,derived formulae for calculating the amount of explosive per hole and spacing between holes.and verified the validity of the model through field trials.
