为了改进沿挖掘周边的岩石挖掘面的平整性,用控制爆破这一术语来说明几个爆破技术问题。杜邦公司已出版了一本优秀的小册子,给出了四种主要的控制爆破方法的一般说明。本报告讨论的大多数问题都选自该出版物。通过多年的现场试验和计算确定了推荐尺寸范围。对于特定的爆破最佳值与地质情况有
In order to improve the smoothness of the rock excavation surface around the excavation, the term blasting is used to describe several blasting techniques. DuPont has published an excellent brochure that gives a general description of the four major methods of controlled blasting. Most of the issues discussed in this report are selected from this publication. The recommended size range has been determined through years of field trials and calculations. For the specific blasting the best value and geological conditions have
