孔内轴向不耦合聚能装药爆破参数研究

Investigation in Blasting Parameters of Discrete Shaped Charge in Small Diameter Boreholes

介绍一种孔内轴向不耦合聚能爆破方法，给出了聚能药包及爆破参数的设计原理和方法，实验结果说明轴向不耦合聚能装药爆破技术是一种实用、方便的岩石切割爆破方法．

A new kind of rock blasting technique with the discrete shaped charges in small diameter boreholer is developed. According to the Principles of fracture mechnics, the formulas of the blasting parameters are provided and the optimal method for the discrete shaped charge parameters is also described in detail. The results of the typical blasting experiments show that the blasting technique with the discrete shaped charge is a practical method for rock cutting blasting in small diameter boreholes.
