Analysis of Effect of Shock-absorption in Presplit Blasting

Cheng Zhang

Abstract

Presplit blasting was applied to an excavation blasting in Zhouning Hydropower Station. In order to monitor its effect of shockabsorption, two series of sensors on the side of wall were patterned to test and measure the vibration, the relevant theory was applied to describe the process of rock blasting and presplit blasting ,a series of data were recorded to analyze its effect of reducing blasting vibration and influential factor.
