Abstract

Eccentric decoupling blasting is commonly used in underground excavation. Determination of perimeter hole parameters (such as the blasthole diameter, spacing, and burden) based on an eccentric charge structure is vital for achieving an excellent smooth blasting effect. In this paper, the Riedel-Hiermaier-Thoma (RHT) model was employed to study rock mass damage under smooth blasting. Firstly, the parameters of the RHT model were calibrated by using the existing SHPB experiment, which were then verified by the existing blasting experiment results. Secondly, the influence of different charge structures on the blasting effect was investigated using the RHT model. The simulation results indicated that eccentric charge blasting has an obvious pressure eccentricity effect. Finally, to improve the blasting effect, the smooth blasting parameters were optimized based on an eccentric charge structure. The overbreak and underbreak phenomena were effectively controlled, and a good blasting effect was achieved with the optimized blasting parameters.

摘要

偏心不耦合爆破是地下开挖中常用的爆破方法。基于偏心装药结构的周边孔参数(如炮孔直径、 间距、装药量等)的确定对获得良好的光面爆破效果至关重要。本文采用Riedel-Hiermaier-Thoma (RHT)模型研究了装药结构对岩体爆破损伤的影响。首先, 利用已有的SHPB实验对RHT模型的参数 进行了标定。其次, 通过室内爆破实验结果对标定参数的合理性进行了验证。然后, 利用RHT模型研 究了不同装药结构对爆破效果的影响。模拟结果表明, 偏心爆破具有明显的压力偏心效应。最后, 为 提高爆破效果, 在偏心装药结构的基础上对光面爆破参数进行了优化。通过优化爆破参数, 有效地控 制了超欠挖现象, 取得了良好的爆破效果。
