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 de-sign 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.
