(一)引言本文讨论了几种爆破方法,其目的是要使已确立的边坡角在保持边坡稳定的前提下达到最陡。尤其以澳大利亚两个大型铁矿山下盘软弱页岩内或附近的爆破为依据,相当详细地讨论爆破能够影响边坡稳定性的几种方法,以及为减少这些影响能够改进的爆破方式。本文讨论了爆破机理、量测方法、以及最终境界区岩石性质的变化。为使对岩石破坏达到
(A) Introduction In this paper, several methods of blasting are discussed, the purpose of which is to reach the steepest slope with the established slope angle while keeping the slope stable. In particular, based on the blasting in or near the weak shales of the two large iron mines in Australia, a number of methods of blasting that can affect slope stability are discussed in considerable detail, together with the blasting methods that can be improved to reduce these effects. This article discusses the mechanism of explosions, methods of measurement, and the changes in rock properties in the final realm. To achieve destruction of the rock
