Application of Hole by Hole Blasting Technique in the Foundation Pit Excavation

Article Preview

Abstract:

The excavation blasting is required for the rock pit of a steel plant in Huangshi city. Due to the chimmey and pool of in-situ concrete foundation are close to the complex environment blasting area, the small hole bench blasting, hole by hole blasting technique were adopted, the reasonable network parameters and millisecond delay time were investigated. Meanwhile the blasting hole was covered for protection. It is shown that the proposed solution can decrease blasting vibration but also control the fly-rocks. The rock blasting effect is favorable and the blasting purpose is achieved.
