SYNOPSIS

Flyrock issues had been in the newspapers and other media regularly every year sometimes with fatalities and other times caused serious damages to properties and also serious injuries to people. Rock blasting at quarries and construction sites is actually an essential part of development work and can be done safely even at location very close to properties. However, highly qualified blasting engineers and experience shotfirers are needed to ensure compliance with safety requirements imposed by the authorities. Low vibration limit and almost no airblast are required to ensure minimum disturbance to the public. Only when blasting is not permitted alternative means such as expansive cement and pyrotechnics materials are considered. The talk will discuss the flyrock issues and mean to tackle it and the alternative means to blasting when and where it is possible. The talk can be useful to project managers or engineers who are likely to be responsible for blasting at their sites.
