摘要
岩石爆破块度预测是岩石爆破研究中的一个重要内容,针对以往爆破块度预测方法的不足,提出了一种新的岩石爆破块度预测方法——数值流形方法。该方法通过对裂纹产生与扩展的处理,能够自动计算出爆破后岩石块体的大小,这为估计岩石爆破块度的大小提供了一条新的思路。最后通过一个数值算例阐述了该方法的应用。
The Fragmentation forecasting of rock blasting is one of the important subjects in study of rock blasting. In light of the shortcomings of the conventional forecasting methods of blasting fragmentation, this paper brings forth a new method for the fragmentation forecasting of rock blasting - numerieal manitold method. Through dealing with the occurrenee and propagation of cracks, this method ean automatically calculate the size of the rock block after blasting, which supplies a new thought for correctly forecasting the fragmentation size of rock blasting. In the end, the application of this method is illustrated by a ease of numerical calculation.
