摘要
基于ANSYS有限元模拟软件,通过定义煤体爆破的裂隙扩展模型,建立深孔预裂爆破影响范围物理模型,计算不耦合系数、控制抽采孔等爆破参数条件下爆破裂隙的扩展形态。
Based on ANSYS finite element simulation software,by defining the crack expansion model of coal blasting,establishes the physical model of the influence range of deep hole pre-splitting blasting, and calculates the expansion form of blasting fracture under the condition of blasting parameters such as uncoupling coefficient and controlled extraction hole.
