摘　　要：井下矿山爆破开采作为矿产资源开发的重要手段,面临爆破振动、冲击波、飞石及有毒有害气体等安全隐患。本文分析了不同装药结构(连续装药、分段装药、不耦合装药)对爆破安全性的影响,对比了不同装药结构的爆破效果。结果表明分段装药和不耦合装药结构在降低爆破振动、冲击波、飞石及气体产物危害方面表现优异,为优化井下矿山爆破开采技术提供了理论支持和实践指导,以供业界参考。As an important means of mineral resource development,underground mining blasting faces safety hazards such as blasting vibration,shock waves,flying stones,and toxic and harmful gases.This article analyzes the impact of different charge structures(continuous charge,segmented charge,uncoupled charge)on blasting safety and compares the blasting effects of different charge structures.The results show that segmented charge and uncoupled charge structures exhibit excellent performance in reducing the hazards of blasting vibration,shock waves,flying rocks,and gas products.This provides theoretical support and practical guidance for optimizing underground mining blasting and mining technology,and serves as a reference for the industry.
