关于瞬时爆破中岩石破碎的机理问题,目前尚有争议。弄清这个问题,对于预裂爆破、光面爆破等实际工程是有意义的。本文应用动态有限元数值计算的一些结果,探讨岩石破碎过程中开裂部位及方向。
There are still controversies about the mechanism of rock fragmentation during instantaneous blasting. To clarify this issue, for the pre-cracking blasting, smooth blasting and other practical projects is of great significance. In this paper, some results of dynamic finite element numerical calculation are used to investigate the location and direction of cracking during rock crushing.
