摘要
在弹性模型的假定下,编制了台阶爆破三维动应力场计算程序,采用最大拉应力等值图分析高台阶爆破中超前压缩填塞方法的动态应力场,讨论了超前压缩法的合理上部药量和填塞长度,为该方法的应用提供了参考依据。
With the hypothesis of elastic model, a computational program of three-dimensional dynamic stress field for bench blasting was developed. This paper, with maximum tensile stress isogram, analyzed the dynamic stress field of leading compressed-tamping method for high-bench blasting and discussed the reasonable upper-part charge quantity and the tamping length of leading compressed-tamping method so as to provide a basis of reference for the application of this method.
