摘要
介绍了PVC(聚氯乙烯)管装药预裂爆破技术在吕梁地区石灰石矿山露天开采的应用。在节理发育的地质条件下,经过精心设计,在近20次的露天深孔预裂爆破试验中,不断优化爆破参数与装药结构,达到了保护最终边坡稳定的效果。
This article introduces the application of PVC pipe charge pre-splitting blasting technology in open-pit mining of limestone mines in the Lvliang area.Under geological conditions with well-developed joints,after careful design and nearly 20 open-pit deep hole pre-splitting blasting tests,the blasting parameters and charging structure were continuously optimized,achieving the effect of protecting the final slope stability.
