Numerical Simulation and Theory Study of Rock Blasting without Interaction Charge

This paper analyzes the domestic and international research of presplit blasting Air-deck Charge technology, and put forward the necessity and urgency of using this technology in the highway construction which through the mountains.

论文分析了国内外预裂爆破空气间隔装药技术的研究现状，并提出了在山区公路修建中使用该技术的必要性和迫切性。

After the theoretical analysis, the numerical modeling determined the best lengthways decoupling coefficient of the presplit blasting Air-deck Charge.

在理论分析的基础上，数值建模研究了空气间隔装药预裂爆破中最佳纵向不耦合系数。

In virtue of the wave solution of plastic dynamic response of plate and the dynamic fracture theory, the critical blasting charge was derived theoretically when onset of initial circumferential crack namely critical damage happened in thin plate subjected to explosions.

应用塑性动力响应波动解及动态断裂理论，从理论上推导了薄钢板在爆炸冲击载荷作用下产生初始环向裂纹即发生临界破坏时的装药量，并得出板的临界位移理论表达式。

The blasting charge, blasting notch high and blast-hole pattern are carefully designed, and the design project of blasting is strictly implemented. Prospective aim of safe production is realized and collapse of chimney is precise.

在装药量、烟囱切口高度，炮孔布置等方面精心设计，并严格按爆破设计方案施工，最终实现了预期的安全生产目标，爆破烟囱精确倒塌。
