在确定露天矿大爆破地震危险边界时,往往未考虑岩体的各向异性,且危险边界多呈圆形。在实际条件下的研究表明,视岩体各向异性和离爆破震中距离的不同,此边界形状会发生变化。在爆破怍业中,偏离地震危险区的实际边界,往往会导致备采矿量不能全部采出,缩小大爆破规模,甚至要迁移本无必要迁移 When determining the seismic hazard boundary of big blasting in open pit mine, the anisotropy of rock mass is often not considered, and the dangerous boundary is mostly round. The research under actual conditions shows that the boundary shape will change depending on the anisotropy of rock mass and the distance in the process of detonation and detonation. In the blasting industry, deviations from the actual boundaries of the seismic danger zone often result in the total amount of reserve mining not being able to be fully recovered, reducing the scale of large explosions, and even moving the unnecessary migration
