Blasting is a widely used technique for rock fragmentation in opencast mines and tunneling projects. Ground vibration is one of the most environmental effects produced by blasting operation. Therefore, the proper prediction of blast-induced ground vibrations is essential to identify safety area of blasting. This paper presents a …
Blasting is a major component of the construction and mining industries in terms of rock fragmentation and concrete demolition. Blast designers are constantly concerned about flyrock and ground vibration induced by blasting as adverse and unintended effects of explosive usage on the surrounding areas. In recent years, several …

Compared to blasting work at quarries and mines, construction blasting needs to be more precise. The blaster needs to take more care because, in most cases, the blasting work is carried out near areas accessible to the public such as residential areas, factories, major roads, railways, etc, where flyrock is not tolerated at all.
