摘　　要：预裂爆破技术通过控制爆炸能量在岩体中的释放,有效保护保留区岩体的完整性和稳定性。本研究针对导爆索预裂爆破的局限性,提出了采用电子雷管替代导爆索的新预裂爆破方案。文章通过理论分析和现场试验,对比了新旧两种方案在爆破效果、装药方式、爆破器材成本等方面的差异。结果表明,新方案不仅实现了良好的爆破效果,还降低了常规预裂爆破方案的爆破器材成本。本研究为预裂爆破技术的优化提供了新思路,证明了采用电子雷管替代导爆索的新预裂爆破方案的技术可行性。Presplitting blasting technology effectively protects the integrity and stability of the reserved rock mass by controlling the release of explosive energy.This paper proposes a new presplitting blasting scheme that uses electronic detonators instead of deto⁃nating cords to address the limitations of presplitting blasting with detonating cords.Through theoretical analysis and on-site experi⁃ments,the differences between the new and old schemes in terms of blasting effect,charging method,and blasting equipment cost are compared.The results show that the new scheme not only achieves good blasting effects,but also reduces the cost of blasting equipment for conventional presplitting blasting schemes.This study provides a new approach for optimizing presplitting blasting technology and demonstrates the technical feasibility of using electronic detonators instead of detonating cords in a new presplitting blasting scheme.
