-
摘要: 本文简要地描述了断裂控制爆破技术的基本原理,然后着重介绍了第一次在国内将该法用于巷道掘进的现场试验结果及其与其他爆破方法的比较和效果评价。结果表明,断裂控制爆破对获得良好的周界控制爆破效果具有重要的工程实际意义。Abstract: Basic concepts of fracture control blasting is described briefly. Field test results with this technique, conducted firstly in tunnelling in China, as well as the comparision with that of other methods of blasting and the evaluation of effectiveness are presented. It is shown that the fracture control blasting is of great importance in engineering practice to achieve a good perimeter control.
