Effects of Shock and Vibration in Blasting
Description
The stress disturbance caused by an explosion in rock mass or other solid media is called an explosion stress wave. The stress wave induced in the rock under blasting mainly includes the shock wave, the compressive stress wave, and the explosion seismic wave (blasting vibration). With the development of engineering techniques, blasting has become a necessary means of construction and has brought great benefits in civil, mining, military, nuclear infrastructure, and other engineering fields. However, the disasters induced by blast shock and vibration are common and severe at the same time, including rock mass instability, damage and collapse of buildings and structures, etc.
In order to meet the demand in the process of rapid social and economic development, scholars from around the world have carried out a lot of research on rock breaking mechanisms and corresponding safety control technology under the influence of blasting shock and vibration. Many new theoretical, numerical, and experimental methods have been proposed and developed to study, predict, and reduce the related adverse effects caused by blasting. This is the key to put forward more reasonable blasting design schemes in the process of rock blasting engineering and demolition blasting engineering, and better develop the blasting effect evaluation index and blasting safety control index reflecting the impact of the explosion stress wave.
This Special Issue provides a forum for researchers to present and discuss the latest theories and methods related to dynamic characteristics of engineering materials and blasting safety control standards from a multidisciplinary perspective, including tunnel blasting, demolition blasting, mining blasting, urban blasting, etc. Original research as well as review articles that describe the current state of the art are welcome.
